[[iPi Mocap Studio]] is a software program provided by [http://www.ipisoft.com iPi Soft LLC] for tracking an actor's motion by analyzing multi-camera (or depth sensor) video recordings. Input videos are recorded with another tool — [[iPi Recorder]].

For storing project data, the proprietary [[.iPiMotion File Extension|'''.iPiMotion''']], [[.iPiCalib File Extension|'''.iPiCalib''']], [[.iPiLocked File Extension|'''.iPiLocked''']], [[.iPiScene File Extension|'''.iPiScene''']] file formats are used which can be handled only by iPi Soft products.

As an output, [[iPi Mocap Studio]] produces a skeleton animation, that then can be applied to an arbitrary target humanlike character. The software includes features for tuning the final animation, such as jitter removal and trajectory filtering. A number of popular formats is supported for target character import and animation export including '''FBX''', '''BVH''', '''Collada''', '''DMX''' and '''SMD'''.

The software comes in [http://ipisoft.com/store/compare-editions/ several editions] which differ by kind and number of cameras supported for tracking. You can [https://files.ipisoft.com/iPiMocapStudioSetup.exe download 30-day trial version] of software for evaluation purposes. In case of any difficulties during installation process please [[iPi Mocap Studio Installation|read the installation instructions]]. If you've decided to purchase, [https://ipisoft.com/store/ go to the Store page] and follow the instructions. After purchase, you will get a license key, which enables you to upgrade the trial version to a selected edition of the software.

* Replaced viewport repaint on every frame during tracking / refine / jitter removal to repaint by timer. May lead to slight speed increase on powerful GPUs.
* Improved tracking / refine / jitter removal speed calcualtion and changed formatting for speed values.
* Using FBX SDK 2017.1 for handling FBX files.
* Fixed speed degradation issue during calibration using board for depth projects.
* For multiple GPU configuration the old tracking algorithm is set to be used in case number of cameras is over 6. In most cases this is faster than using default tracking on single GPU.

 N E W    F E A T U R E S:
* Increased speed of tracking operations.
** Maximum speed increase (up to 3-4 times) is achieved at high-performance video cards for projects recorded with 1 or 2 Kinect sensors.
** For 4 or more Sony PS3 Eye cameras speed gain is lower and can reach 10 – 50% depending on particular tracking options and hardware configuration.
** For slow video cards speed increase is substantially lower.
** For projects recorded with many cameras tracking speed can even be lower compared to previous version on particular hardware configurations. You have the option to use the old tracking algorithm then (you can select this option in Advanced Tracking Settings section of the Tracking tab)
** For multiple GPU configuration the new algorithm will be used if number of cameras / sensors is not more than 4 (in this case only the primary GPU is used). In most cases this will still be faster than using multiple GPUs with the old tracking algorithm. For more than 4 cameras the old algorithm on multiple GPUs will be used, as a faster option.

[[iPi Mocap Studio]] is a software program provided by [http://www.ipisoft.com iPi Soft LLC] for tracking an actor's motion by analyzing multi-camera (or depth sensor) video recordings. Input videos are recorded with another tool — [[iPi Recorder]].

For storing project data, the proprietary [[.iPiMotion File Extension|'''.iPiMotion''']], [[.iPiCalib File Extension|'''.iPiCalib''']], [[.iPiLocked File Extension|'''.iPiLocked''']], [[.iPiScene File Extension|'''.iPiScene''']] file formats are used which can be handled only by iPi Soft products.

As an output, [[iPi Mocap Studio]] produces a skeleton animation, that then can be applied to an arbitrary target humanlike character. The software includes features for tuning the final animation, such as jitter removal and trajectory filtering. A number of popular formats is supported for target character import and animation export including '''FBX''', '''BVH''', '''Collada''', '''DMX''' and '''SMD'''.

The software comes in [http://ipisoft.com/store/compare-editions/ several editions] which differ by kind and number of cameras supported for tracking. You can [https://files.ipisoft.com/iPiMocapStudioSetup.exe download 30-day trial version] of software for evaluation purposes. In case of any difficulties during installation process please [[iPi Mocap Studio Installation|read the installation instructions]]. If you've decided to purchase, [https://ipisoft.com/store/ go to the Store page] and follow the instructions. After purchase, you will get a license key, which enables you to upgrade the trial version to a selected edition of the software.

Information about the latest updates of [[iPi Mocap Studio]] can be found in the [[iPi Mocap Studio Release Notes|release notes]].

Animation Export

2025-05-20T10:57:52Z

Andrew: /* How to Loop Animation */

=== Animation Export ===

To export tracked motion, follow simple steps below.
# Select '''Export''' tab
# Select rig from the list of available rigs or import your custom model
#:{{Note|The motions will be automatically transferred to selected rig (except ''Default iPi Rig'', that does not require motion transfer). See details on motion transfer [[Animation_Export#Motion_Transfer| below]])}}
# Press '''Export button''' or use '''File > Export Animation''' menu item to export all animation frames from within Region of Interest (ROI).
#:{{Note|To export animation for specific take, right-click on take and select '''Export Animation''' item from pop-up menu.}}
# Select output file format

[[Image:ExportTab-1.png|thumb|600px|center]]

=== Motion Transfer ===
==== Default iPi Character Rig ====

The default skeleton in [[iPi Mocap Studio]] is optimized for markerless motion capture. It may or may not be suitable as a skeleton for your character. Default iPi skeleton in T-pose has non-zero rotations for all joints. Please note that default iPi skeleton with zero rotations does not represent a meaningful pose and looks like a random pile of bones.
<table border=0><tr>
<td>[[Image:default rig 1.png|thumb|350px|Default rig]]</td>
<td>[[Image:default rig with names 1.png|thumb|350px|Bone names]]</td>
</tr></table>

By default [[iPi Mocap Studio]] exports a T-pose (or a reasonable default pose for custom rig after motion transfer) in the first frame of animation. In case when it is not desired switch off '''Export T-pose in first frame''' checkbox.

==== Other rigs ====
[[iPi Mocap Studio]] has integrated motion transfer technology that allows to automatically transfer motion to a custom rig.
# Select '''Export''' tab
# Select rig from the list of available rigs or import your custom model
#:{{Note|The motions will be automatically transferred to selected rig (except ''Default iPi Rig'', that does not require motion transfer). You will be able to see the transferred motion in the viewport}}
# You may need to assign bone mappings on the '''Export''' tab for motion transfer to work correctly.
# You can save your motion transfer profile to XML file for future use.

{{Tip|[[iPi Mocap Studio]] has pre-configured motion transfer profiles for many popular rigs (see below).}}

{{Note|If you export animation to format different from format your target character was imported in, only rig will be exported. If you use the same format for export, skin will be exported as well.}}

[[Image:ExportTab-2.png|thumb|600px|center]]

Starting with version 3.5, iPi Mocap Studio supports rotation of imported character into proper orientation. This is useful for many popular characters, including Unreal Engine standard character.

[[Image:Animation-Export-Orientation-1.png|center]]

Starting with version 3.5, iPi Mocap Studio can map hips motion either to ''Root/Ground'' or to ''Hips/Pelvis''. This is useful for game engine characters, including standard Unity 3D Engine and Unreal Engine characters.

[[Image:Export-Root-1.png|thumb|600px|center]]

==== Multiple Target Bones ====

Bone mapping allows to specify multiple target bones. This can use used if:

* Target character is more detailed so one bone in default iPi character rig corresponds to multiple bones in target character (i.e. your character has more spine bones)
* Your character has separate bones for swing and twist rotation channels

To map source character bone to multiple target bones you need to use ''Add a target bone'' item in a ''Manage target bones'' context menu. You then set weights for splitting the source rotation.

{{Note|The default values are equal rotation split. Weights are specified separately for swing and twist rotation channels.}}

[[Image:Animation-Export-Multiple-Targets-1.png|center]]

=== How to Loop Animation ===

[[iPi Mocap Studio]] can seamlessly loop animation on export. To get perfectly looping animation, turn on '''Loop animation''' option in '''Export Options''' dialog:

[[Image:loop-animation-option.png]]

{{Note|'''Store removed translation to root''' option is available only when '''Loop animation''' option is turned on and target character has the '''root''' joint.}}

=== Export Pipelines for Popular 3D Packages ===

==== MotionBuilder ====

Select ''Motion Builder'' target character on '''Export''' tab and export animation to BVH or FBX.

[[Image:export mb.png]]

==== 3D MAX Biped ====

# Select ''3ds Max Biped'' target character on '''Export''' tab and export animation to BVH or FBX.
# Create a Biped character in 3D MAX ('''Create > Systems > Biped''').
# Put your Biped character to your 3d scene.
# Go to '''Motion''' tab. Click '''Motion Capture''' button and import your BVH or FBX file.

<table border=0><tr>
<td>[[Image:export 3dmax step1 1.png|thumb|400px|Step 1]]</td>
<td>[[Image:export 3dmax step2.png|thumb|300px|Step 2]]</td>
</tr></table>
<table border=0><tr>
<td>[[Image:export 3dmax step3.png|thumb|500px|Step 3]]</td>
<td>[[Image:export 3dmax step4.png|thumb|200px|Step 4]]</td>
</tr></table>

Our user '''Cra0kalo''' created an example [https://www.ipisoft.com/forum/viewtopic.php?f=2&t=4928 Valve Biped rig for use with 3D MAX]. It may be useful if you work with Valve Source Engine characters.

==== Maya ====

Latest versions of Maya (starting with Maya 2011) have a powerful biped animation subsystem called "HumanIK". Animations exported from [[iPi Mocap Studio]] in [[Animation_Export#MotionBuilder|MotionBuilder-friendly format]] should work fine with Maya 2011 and HumanIK. The following video tutorials can be helpful:

* [http://vimeo.com/57823600 Maya HumanIK Mocap retarget with iPi Mocap Studio, by Wes McDermott]
* [http://www.youtube.com/watch?v=l1hV8BqsCEA Non-Destructive Live Retargeting — Maya 2011 New Features]
* [http://vimeo.com/24351989 Motion Capture Workflow With Maya 2011]

For older versions of Maya please see the [[#Other_rigs]] section. Recommended format for import/export with older versions of Maya is FBX.

==== Unreal Engine ====

[[iPi Mocap Studio]] has built-in motion transfer profile for ''UE4 Unreal Mannequin'' (default Unreal character) and ''MetaHuman'' character. So select the corrensponding target character, export animation to FBX and then import it into Unreal.

==== FBX ====

[[iPi Mocap Studio]] supports FBX format for import/export of animations and characters. When exporting animation, you are presented with several options:
* Which version of FBX format to use, ranging from 6.1 (2010 product line) to 7.4 (2015 product line)
* Produce text or binary file
The default values are defined by an imported character (if any), otherwise set to recently used values.

Some applications do not use the latest FBX SDK and may have problems importing FBX files of newer versions. In case of such problems, your can use Autodesk's free [http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=10775855 FBX Converter] to convert your animation file to an appropriate FBX version.

==== COLLADA ====

[[iPi Mocap Studio]] supports [http://collada.org COLLADA] format for import/export of animations and characters. Current version of [[iPi Mocap Studio]] exports COLLADA animations as matrices. In case if you encounter incompatibilities with other applications' implementation of COLLADA format, we recommend using Autodesk's free [http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=10775855 FBX Converter] to convert your data between FBX and COLLADA formats. FBX is known to be more universally supported in many 3D graphics packages.

==== LightWave ====

Recommended format for importing target characters from LightWave to iPi Studio is FBX. Recommended format for bringing animations from [[iPi Mocap Studio]] to LightWave is BVH or FBX.

==== SoftImage|XSI ====

Our user Eric Cosky published a tutorial on using [[iPi Mocap Studio]] with SoftImage|XSI:

https://www.ipisoft.com/forum/viewtopic.php?f=13&p=9660#p9660

==== Poser ====

# Export your poser character in T-pose in BVH format ('''File > Export''').
# Import your Poser character skeleton into [[iPi Mocap Studio]]. Your animation will be transferred to your Poser character.
# Export your animation to BVH format.
# Import exported BVH to Poser

{{Tip|Poser 8 has a bug with incorrect wrists animation import. The bug can be reproduced as follows: export Poser 8 character in T-pose in BVH format; import your character back into Poser 8; note how wrists are twisted unnaturally as the result.<br>A workaround for wrists bug is to chop off wrists from your Poser 8 skeleton (for instance using BVHacker) before importing Poser 8 target character into [[iPi Mocap Studio]]. Missing wrists should not cause any problems during motion transfer in [[iPi Mocap Studio]] if your BVH file is edited correctly. Poser will ignore missing wrists when importing resulting motion so the resulting motion will look right in Poser (wrists in default pose as expected).}}

==== DAZ 3D Genesis 8 ====
# Just select built-in ''Genesis 8 Male'' or ''Genesis 8 Female'' rig as target character.
# Export your animation to BVH format.
# Import exported BVH to DAZ Studio.
#* Turn off limits and locks for all joints.
#** Right click the root node of figure > Select > Select children.
#** Edit > Figure > Limits > Limits Off.
#** If you need to unlock nodes, use Edit > Figure > Locks > Unlock Selected Node(s).
#* Import BVH file you exported from [[iPi Mocap Studio]].

==== iClone 8 ====

If you use default iClone character, our users recommend this simple workflow:
# Select ''Motion Builder'' target character on '''Export''' tab and export animation to BVH.
# Select ''Mixamo Default Character'' profile when importing BVH to iClone.

==== iClone 3 ====

{{Note|Modern versions of iClone work smoothly with iPi Soft. Instructions below are only for iClone 3}}

{{Note|Current version of iPi Studio can only export animation in iClone-compatible BVH format. The iMotion format is not supported. That means you will need iClone PRO to be able to import the motion into iClone. Standard and EX versions of iClone do not have BVH Converter and therefore cannot import BVH files.}}

Workflow for iClone is straightforward.
# Select ''iClone'' target character on '''Export''' tab and export animation to BVH.
# Go to '''Animation''' tab in iClone and launch BVH Converter.
# Import your BVH file with Default profile, click '''Convert'''
# Save the resulting animation in iMotion format. Now your animation can be applied to iClone characters.

{{Tip|iClone expects an animation sampled at 15 frames per seconds. For other frame rates, you may need to create a custom BVH Converter profile by copying Default profile and editing '''Frame Rate''' setting.}}

{{Note|BVH Converted in iClone 4 has a bug that causes distortion of legs animation. [[iPi Mocap Studio]] exports an iClone-optimized BVH correctly as can be verified by reviewing exported BVH motion in BVHacker or MotionBuilder or other third-party application. No workaround is known. We recommend that you contact iClone developers about this bug as it is out of control of iPi Soft.}}

==== Valve Source Engine SMD ====

[[Animation_Export#Other_rigs|Transfer motions]] to your Valve Source Engine character (stored in .smd file) and export your animation in Valve Source Engine SMD format.

Our user '''Cra0kalo''' created an example [https://www.ipisoft.com/forum/viewtopic.php?f=2&t=4928 Valve Biped rig for use with 3D MAX]. It may be useful if you wish to apply more then one capture through MotionBuilder or edit the custom keyframes in MAX.

==== Valve Source Filmmaker ====

===== DMX =====

First, you need to import your character (or its skeleton) into [[iPi Mocap Studio]], for motion transfer.

There are currently 3 ways of doing this:

# You can import an animation DMX (in default pose) into [[iPi Mocap Studio]]. Since it has a skeleton, it should be enough for motion transfer. To create an animation DMX with default pose, you can add your character to your scene in Source Filmmaker and export DMX for corresponding animation node:
#* open '''Animation Set Editor Tab''';
#* click '''+''' > '''Create Animation Set for New Model''';
#* choose a model and click '''Open''';
#* export animation for your model, in '''ASCII''' DMX format;
#*: ''There is a checkbox named '''Ascii''' in the top area of the export dialog.''
# Alternatively, you can just import an SMD file with your character into [[iPi Mocap Studio]]. For example, SMD files for all Team Fortress 2 characters can be found in your SDK in a location similar to the following (you need to have Source SDK installed): C:\Program Files (x86)\Steam\steamapps\<your steam name>\sourcesdk_content\tf\modelsrc\player\pyro\parts\smd\pyro_model.smd).
# If you created a custom character in Maya, you should be able to export it in DMX model fromat. (Please [https://developer.valvesoftware.com/wiki/Maya see Valve documentation] on how to do this).

Then you can import your model DMX into iPi Mocap Studio. Current version of [[iPi Mocap Studio]] cannot display character skin, but it should display the skeleton. Skeleton should be enough for motion transfer.

To export animation in DMX, press '''Export Animation''' button on the '''Export''' tab in [[iPi Mocap Studio]] and choose '''DMX''' from the list of supported formats. You may also want to uncheck '''Export T-pose in first frame''' option on the '''Export''' tab in [[iPi Mocap Studio]].

Now you can import your animation into Source Filmmaker. There will be some warnings about missing channels for face bones but you can safely ignore them.

===== Old way involving Maya =====

This was used until [[iPi Mocap Studio]] got DMX support. And still may be useful in case of any troubles with DMX. Please see the following video tutorial series:

Evolver offers several different skeletons for Evolver characters. Here is an example motion transfer profile for Evolver "Gaming" skeleton: [https://www.ipisoft.com/downloads/motion_transfer_profiles/evolver_game.profile.xml evolver_game.profile.xml]

==== Second Life ====

[[Animation_Export#Other_rigs|Transfer motions]] to your Second Life character (stored in BVH file) and export your animation in BVH format.

[https://wiki.secondlife.com/wiki/How_to_create_animations#Setting_up_Poser SecondLife documentation] contains a link to useful [http://static-secondlife-com.s3.amazonaws.com/downloads/avatar/avatar_mesh.zip SL avatar files]. The ZIP file includes a BVH of the "default pose". Be sure to have that.

Andrew: How to Loop Animation

=== Animation Export ===

To export tracked motion, follow simple steps below.
# Select '''Export''' tab
# Select rig from the list of available rigs or import your custom model
#:{{Note|The motions will be automatically transferred to selected rig (except ''Default iPi Rig'', that does not require motion transfer). See details on motion transfer [[Animation_Export#Motion_Transfer| below]])}}
# Press '''Export button''' or use '''File > Export Animation''' menu item to export all animation frames from within Region of Interest (ROI).
#:{{Note|To export animation for specific take, right-click on take and select '''Export Animation''' item from pop-up menu.}}
# Select output file format

[[Image:ExportTab-1.png|thumb|600px|center]]

=== Motion Transfer ===
==== Default iPi Character Rig ====

The default skeleton in [[iPi Mocap Studio]] is optimized for markerless motion capture. It may or may not be suitable as a skeleton for your character. Default iPi skeleton in T-pose has non-zero rotations for all joints. Please note that default iPi skeleton with zero rotations does not represent a meaningful pose and looks like a random pile of bones.
<table border=0><tr>
<td>[[Image:default rig 1.png|thumb|350px|Default rig]]</td>
<td>[[Image:default rig with names 1.png|thumb|350px|Bone names]]</td>
</tr></table>

By default [[iPi Mocap Studio]] exports a T-pose (or a reasonable default pose for custom rig after motion transfer) in the first frame of animation. In case when it is not desired switch off '''Export T-pose in first frame''' checkbox.

==== Other rigs ====
[[iPi Mocap Studio]] has integrated motion transfer technology that allows to automatically transfer motion to a custom rig.
# Select '''Export''' tab
# Select rig from the list of available rigs or import your custom model
#:{{Note|The motions will be automatically transferred to selected rig (except ''Default iPi Rig'', that does not require motion transfer). You will be able to see the transferred motion in the viewport}}
# You may need to assign bone mappings on the '''Export''' tab for motion transfer to work correctly.
# You can save your motion transfer profile to XML file for future use.

{{Tip|[[iPi Mocap Studio]] has pre-configured motion transfer profiles for many popular rigs (see below).}}

{{Note|If you export animation to format different from format your target character was imported in, only rig will be exported. If you use the same format for export, skin will be exported as well.}}

[[Image:ExportTab-2.png|thumb|600px|center]]

Starting with version 3.5, iPi Mocap Studio supports rotation of imported character into proper orientation. This is useful for many popular characters, including Unreal Engine standard character.

[[Image:Animation-Export-Orientation-1.png|center]]

Starting with version 3.5, iPi Mocap Studio can map hips motion either to ''Root/Ground'' or to ''Hips/Pelvis''. This is useful for game engine characters, including standard Unity 3D Engine and Unreal Engine characters.

[[Image:Export-Root-1.png|thumb|600px|center]]

==== Multiple Target Bones ====

Bone mapping allows to specify multiple target bones. This can use used if:

* Target character is more detailed so one bone in default iPi character rig corresponds to multiple bones in target character (i.e. your character has more spine bones)
* Your character has separate bones for swing and twist rotation channels

To map source character bone to multiple target bones you need to use ''Add a target bone'' item in a ''Manage target bones'' context menu. You then set weights for splitting the source rotation.

{{Note|The default values are equal rotation split. Weights are specified separately for swing and twist rotation channels.}}

[[Image:Animation-Export-Multiple-Targets-1.png|center]]

=== How to Loop Animation ===

[[iPi Mocap Studio]] can seamlessly loop animation on export. To get perfectly looping animation, turn on '''Loop animation''' option in '''Export Options''' dialog:

[[Image:loop-animation-option.png]]

=== Export Pipelines for Popular 3D Packages ===

==== MotionBuilder ====

Select ''Motion Builder'' target character on '''Export''' tab and export animation to BVH or FBX.

[[Image:export mb.png]]

==== 3D MAX Biped ====

# Select ''3ds Max Biped'' target character on '''Export''' tab and export animation to BVH or FBX.
# Create a Biped character in 3D MAX ('''Create > Systems > Biped''').
# Put your Biped character to your 3d scene.
# Go to '''Motion''' tab. Click '''Motion Capture''' button and import your BVH or FBX file.

Our user '''Cra0kalo''' created an example [https://www.ipisoft.com/forum/viewtopic.php?f=2&t=4928 Valve Biped rig for use with 3D MAX]. It may be useful if you work with Valve Source Engine characters.

==== Maya ====

Latest versions of Maya (starting with Maya 2011) have a powerful biped animation subsystem called "HumanIK". Animations exported from [[iPi Mocap Studio]] in [[Animation_Export#MotionBuilder|MotionBuilder-friendly format]] should work fine with Maya 2011 and HumanIK. The following video tutorials can be helpful:

* [http://vimeo.com/57823600 Maya HumanIK Mocap retarget with iPi Mocap Studio, by Wes McDermott]
* [http://www.youtube.com/watch?v=l1hV8BqsCEA Non-Destructive Live Retargeting — Maya 2011 New Features]
* [http://vimeo.com/24351989 Motion Capture Workflow With Maya 2011]

For older versions of Maya please see the [[#Other_rigs]] section. Recommended format for import/export with older versions of Maya is FBX.

==== Unreal Engine ====

[[iPi Mocap Studio]] has built-in motion transfer profile for ''UE4 Unreal Mannequin'' (default Unreal character) and ''MetaHuman'' character. So select the corrensponding target character, export animation to FBX and then import it into Unreal.

==== FBX ====

[[iPi Mocap Studio]] supports FBX format for import/export of animations and characters. When exporting animation, you are presented with several options:
* Which version of FBX format to use, ranging from 6.1 (2010 product line) to 7.4 (2015 product line)
* Produce text or binary file
The default values are defined by an imported character (if any), otherwise set to recently used values.

Some applications do not use the latest FBX SDK and may have problems importing FBX files of newer versions. In case of such problems, your can use Autodesk's free [http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=10775855 FBX Converter] to convert your animation file to an appropriate FBX version.

==== COLLADA ====

[[iPi Mocap Studio]] supports [http://collada.org COLLADA] format for import/export of animations and characters. Current version of [[iPi Mocap Studio]] exports COLLADA animations as matrices. In case if you encounter incompatibilities with other applications' implementation of COLLADA format, we recommend using Autodesk's free [http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=10775855 FBX Converter] to convert your data between FBX and COLLADA formats. FBX is known to be more universally supported in many 3D graphics packages.

==== LightWave ====

Recommended format for importing target characters from LightWave to iPi Studio is FBX. Recommended format for bringing animations from [[iPi Mocap Studio]] to LightWave is BVH or FBX.

==== SoftImage|XSI ====

Our user Eric Cosky published a tutorial on using [[iPi Mocap Studio]] with SoftImage|XSI:

https://www.ipisoft.com/forum/viewtopic.php?f=13&p=9660#p9660

==== Poser ====

# Export your poser character in T-pose in BVH format ('''File > Export''').
# Import your Poser character skeleton into [[iPi Mocap Studio]]. Your animation will be transferred to your Poser character.
# Export your animation to BVH format.
# Import exported BVH to Poser

{{Tip|Poser 8 has a bug with incorrect wrists animation import. The bug can be reproduced as follows: export Poser 8 character in T-pose in BVH format; import your character back into Poser 8; note how wrists are twisted unnaturally as the result.<br>A workaround for wrists bug is to chop off wrists from your Poser 8 skeleton (for instance using BVHacker) before importing Poser 8 target character into [[iPi Mocap Studio]]. Missing wrists should not cause any problems during motion transfer in [[iPi Mocap Studio]] if your BVH file is edited correctly. Poser will ignore missing wrists when importing resulting motion so the resulting motion will look right in Poser (wrists in default pose as expected).}}

==== DAZ 3D Genesis 8 ====
# Just select built-in ''Genesis 8 Male'' or ''Genesis 8 Female'' rig as target character.
# Export your animation to BVH format.
# Import exported BVH to DAZ Studio.
#* Turn off limits and locks for all joints.
#** Right click the root node of figure > Select > Select children.
#** Edit > Figure > Limits > Limits Off.
#** If you need to unlock nodes, use Edit > Figure > Locks > Unlock Selected Node(s).
#* Import BVH file you exported from [[iPi Mocap Studio]].

==== iClone 8 ====

If you use default iClone character, our users recommend this simple workflow:
# Select ''Motion Builder'' target character on '''Export''' tab and export animation to BVH.
# Select ''Mixamo Default Character'' profile when importing BVH to iClone.

==== iClone 3 ====

{{Note|Modern versions of iClone work smoothly with iPi Soft. Instructions below are only for iClone 3}}

{{Note|Current version of iPi Studio can only export animation in iClone-compatible BVH format. The iMotion format is not supported. That means you will need iClone PRO to be able to import the motion into iClone. Standard and EX versions of iClone do not have BVH Converter and therefore cannot import BVH files.}}

Workflow for iClone is straightforward.
# Select ''iClone'' target character on '''Export''' tab and export animation to BVH.
# Go to '''Animation''' tab in iClone and launch BVH Converter.
# Import your BVH file with Default profile, click '''Convert'''
# Save the resulting animation in iMotion format. Now your animation can be applied to iClone characters.

{{Tip|iClone expects an animation sampled at 15 frames per seconds. For other frame rates, you may need to create a custom BVH Converter profile by copying Default profile and editing '''Frame Rate''' setting.}}

{{Note|BVH Converted in iClone 4 has a bug that causes distortion of legs animation. [[iPi Mocap Studio]] exports an iClone-optimized BVH correctly as can be verified by reviewing exported BVH motion in BVHacker or MotionBuilder or other third-party application. No workaround is known. We recommend that you contact iClone developers about this bug as it is out of control of iPi Soft.}}

==== Valve Source Engine SMD ====

[[Animation_Export#Other_rigs|Transfer motions]] to your Valve Source Engine character (stored in .smd file) and export your animation in Valve Source Engine SMD format.

Our user '''Cra0kalo''' created an example [https://www.ipisoft.com/forum/viewtopic.php?f=2&t=4928 Valve Biped rig for use with 3D MAX]. It may be useful if you wish to apply more then one capture through MotionBuilder or edit the custom keyframes in MAX.

==== Valve Source Filmmaker ====

===== DMX =====

First, you need to import your character (or its skeleton) into [[iPi Mocap Studio]], for motion transfer.

There are currently 3 ways of doing this:

# You can import an animation DMX (in default pose) into [[iPi Mocap Studio]]. Since it has a skeleton, it should be enough for motion transfer. To create an animation DMX with default pose, you can add your character to your scene in Source Filmmaker and export DMX for corresponding animation node:
#* open '''Animation Set Editor Tab''';
#* click '''+''' > '''Create Animation Set for New Model''';
#* choose a model and click '''Open''';
#* export animation for your model, in '''ASCII''' DMX format;
#*: ''There is a checkbox named '''Ascii''' in the top area of the export dialog.''
# Alternatively, you can just import an SMD file with your character into [[iPi Mocap Studio]]. For example, SMD files for all Team Fortress 2 characters can be found in your SDK in a location similar to the following (you need to have Source SDK installed): C:\Program Files (x86)\Steam\steamapps\<your steam name>\sourcesdk_content\tf\modelsrc\player\pyro\parts\smd\pyro_model.smd).
# If you created a custom character in Maya, you should be able to export it in DMX model fromat. (Please [https://developer.valvesoftware.com/wiki/Maya see Valve documentation] on how to do this).

Then you can import your model DMX into iPi Mocap Studio. Current version of [[iPi Mocap Studio]] cannot display character skin, but it should display the skeleton. Skeleton should be enough for motion transfer.

To export animation in DMX, press '''Export Animation''' button on the '''Export''' tab in [[iPi Mocap Studio]] and choose '''DMX''' from the list of supported formats. You may also want to uncheck '''Export T-pose in first frame''' option on the '''Export''' tab in [[iPi Mocap Studio]].

Now you can import your animation into Source Filmmaker. There will be some warnings about missing channels for face bones but you can safely ignore them.

* Increased speed of tracking operations.
** Maximum speed increase (up to 3-4 times) is achieved at high-performance video cards for projects recorded with 1 or 2 Kinect sensors.
** For 4 or more Sony PS3 Eye cameras speed gain is lower and can reach 10 – 50% depending on particular tracking options and hardware configuration.
** For slow video cards speed increase is substantially lower.
** For projects recorded with many cameras tracking speed can even be lower compared to previous version on particular hardware configurations. You have the option to use the old tracking algorithm then (you can select this option in Advanced Tracking Settings section of the Tracking tab)
** For multiple GPU configuration the new algorithm will be used if number of cameras / sensors is not more than 4 (in this case only the primary GPU is used). In most cases this will still be faster than using multiple GPUs with the old tracking algorithm. For more than 4 cameras the old algorithm on multiple GPUs will be used, as a faster option.

== 3rd Party Libraries Installation ==

To be able to use AI-based features, you should download and install [https://github.com/NVIDIA/MAXINE-AR-SDK#readme NVIDIA Maxine AR 0.8.2] runtime by your own. It can be done either by downloading appropriate version of AR 0.8.2 runtime from the following page [https://www.nvidia.com/broadcast-sdk-resources], or via the following dialog that [[iPi Mocap Studio]] automatically shows when AI-based detectors are required but [https://github.com/NVIDIA/MAXINE-AR-SDK#readme NVIDIA Maxine AR 0.8.2] runtime cannot be found in the system:

<center>[[File:maxine-ar-0 8 2-required-dlg.png]]</center>

== Limitations of Current Version ==

Currently, AI-based features are only available for the following types of projects/videos:
* Multi camera RGB video, single actor
* Single or multi depth sensor video with color data, single actor

''That is, if your project contains multiple actors or it is recorded with the aid of depth sensor(s) without color data (only depth maps, no RGB images) then you are unable to use new AI-based features.''

== How to Use ==

=== Detect Pose (AI) ===

This feature is available on two Tabs: '''Actor''' and '''Tracking'''.

<center><table border="0">
<tr><td>[[File:actor-detect-pose-ai.png]]</td><td>  </td><td>[[File:tracking-detect-pose-ai.png]]</td></tr>
</table></center>

In both cases, AI pose detector is applied to all available RGB images in the current frame, after that detection results are combined from all cameras, post-processed and Inverse Kinematics (IK) is used to produce pose of 3D character. This functionality is very useful to set initial pose before tracking or to fix tracking errors.

{{Tip|You can visualize raw output of AI detector for each camera by selecting '''View > Raw AI Skeleton''' item in the main menu. ''Raw AI Skeleton'' is shown as green balls connected with yellow sticks. Switch between cameras to see results for each camera.}}

<center>[[File:view-raw-ai-skeleton.png]]</center>

After that, you can apply Refit Pose in most cases to refine 3D character position based on iPi proprietary tracking algorithms. However, please remember that correct actor parameters must be specified before using of Refit Pose.

=== Detect Pose and Height (AI) ===

'''Detect Pose and Height (AI)''' is available on '''Actor''' tab as an item in drop-down menu under '''Auto Adjust Actor Pose''' button. This feature works similar to the previous one but in addition to pose detection, it estimates actor’s height. The accuracy of such detection depends on pose, cameras views, etc. In most cases, it is better to set height manually if you know it. However, you can try it and decide for your own is it useful or not.

<center>[[File:actor-detect-pose-and-height-ai.png]]</center>

=== AI-based feet tracking ===

Now there are three options for feet tracking:
# '''Do not track'''. Feet are not tracked and have default position (zero rotation) in all frames. Corresponds to unchecked state of '''Enable foot tracking''' checkbox in previous versions of [[iPi Mocap Studio]].
# '''Track'''. Proprietary iPi algorithms are used to track feet. Corresponds to checked state of '''Enable foot tracking''' checkbox in previous versions of [[iPi Mocap Studio]].
# '''Track (AI-based)'''. AI detectors are used to determine feet positions in each frame during tracking pass. First introduced in version '''4.6.0.'''

''In some cases, iPi proprietary algorithms work better for feet, but for other videos AI-based tracking can be really useful.''

<center><table border="0">
<tr><td>[[File:tracking-settings-feet_4_6_0.png]]</td><td>  </td><td>[[File:tracking-settings-feet_4_5_8.png]]</td></tr>
<tr><th>v.4.6.0</th><th></th><th>v.4.5.8</th></tr>
</table></center>

{{Tip|AI-based tracking is very noisy. For this reason, please do not forget to apply aggressive [[Automatic_Refinement_and_Filtering|Jitter Removal]] for body parts tracked with the help of AI.}}

=== AI-based head tracking ===

Similar to feet tracking, head position can be tracked with the aid of iPi proprietary algorithms or based on AI detectors. Again, for some videos (especially depth ones) AI-based approach can be more accurate than iPi one.

=== AI-based hands tracking ===

In addition to feet and head, AI-based tracking can be applied to hands. Currently, only rotations for hands is supported. Neither thumb nor fingers positions are tracked. Use key framing for fingers, as before. In addition, accuracy of hands rotations determined by AI-based algorithms depends on hands visibility in cameras.

<center>[[File:tracking-settings-hands-ai.png]]</center>

=== Applying only AI-based tracking ===

When one chooses AI-based tracking for Head/Hands/Feet, it applies during standard Tracking Forward/Backward pass along with iPi incremental tracking for full body. But when tracking has already performed and there is no need to re-track frames in ROI, one can apply only AI-based tracking for Head/Hands/Feet (depending on selected settings for them). To do it, click on down arrow in the right part of '''Track Forward/Backward''' buttons and choose '''AI-based Only''' item in drop-down menu. This could be helpful during experiments with different AI options because it allows applying changes fast.

<center>[[File:tracking-ai-based-only.png]]</center>

{{Note|If AI-based tracking is not selected for any body part, or tracking is turned off for all individual body parts that requires AI-based tracking, then '''AI-based Only''' option is not available in the drop-down menu.}}

=== Automatic tracking errors fixing ===

As was stated before, AI-based pose detection can help in fixing of tracking errors:
* Choose frame with erroneous pose after tracking
* Click '''Detect Pose (AI)''' button to set pose roughly based on AI detectors
* Then click '''Refit Pose''' button to refine detected pose

In most cases, it should fix pose in the selected frame. But what to do when there are many sequential frames with erroneous poses? First, it is worth to try re-tracking in different direction from the fixed pose. It could help. If not then new '''Auto Fix Pose (AI-based)''' tracking option should be applied.

<center>[[File:tracking-auto-fix-pose-ai.png]]</center>

This option applies '''Detect Pose (AI)''' followed by '''Refit Pose''' actions for each frame in Forward/Backward directions, starting from the current frame.

{{Note|This approach is applicable even when AI-based tracking is not selected for any body part.}}

How to Build Synced Multi-Camera Video

2023-09-05T16:29:41Z

Andrew: /* Synchronization */

== Introduction ==

To process video recorded by action cameras (or other standalone camcorders) in [[iPi Mocap Studio]] you have to create multi-camera [[.iPiVideo File Extension|.iPiVideo]] file from separate MP4/MOV/AVI/MPEG video files recorded by these cameras:

<center>[[File:build-combined-video-workflow-schema.png|1000px|link=]]</center>

== Preparations ==

First of all, copy MP4/MOV/AVI/MPEG video files from each camera to computer.

There are two hints here:
# It's better to use microSD-card reader to copy files because it provides much higher speed of this operation in comparison with USB-connection.
# To distinguish files from different cameras it is convenient to create a sub-folder for each camera. And name of such sub-folder should contain label/nickname of corresponding camera.<br/>For example: if you have cameras with labels/names "cam1", "cam2", "cam3" and "cam4" then you can create the following structure of folders and files on your local disk:
YYYY-MM-DD-session-name
cam1
video files from "cam1" camera
cam2
video files from "cam2" camera
cam3
video files from "cam3" camera
cam4
video files from "cam4" camera
:: Alternatively you can rename video files right after copying (or even during copying) to local disk while you still remember which camera has produced those files. Such approach is used in the following sample: [[Sample Videos and Projects (four GoPro)]].

== Overall Procedure ==

* Run [[iPi Recorder]] and click '''Build Combined Video''' button in the toolbar at the home screen.
<center>[[File:build-combined-video-tool-button.png|500px|link=]]</center>
* For each camera:
** add video from this camera by clicking '''Add Video''' button in the toolbar — see mark '''(1)''' on screenshot below
** choose this camera by clicking on the image from this camera — '''(2)'''
** in the left panel '''(3)''' set camera parameters by clicking on '''Load''' button in '''camera parameters''' section — '''(4)'''
*** choose appropriate '''.iPiCam''' file you saved for this camera during [[How to Calibrate Camera Optics|camera optics calibration]]
* Now videos from all cameras are added.
* Define synchronization between cameras:
** automatically:
*** if you're using flashes as sync events then simply click '''Sync by Flashes''' button on toolbar — '''(E)'''
*** and check correctness of automatic synchronization
** or manually:
*** for each camera, click button '''Edit''' in '''sync frame''' section of the left panel '''(3)''' and choose a frame with synchronization event — '''(5)'''
** for details see [[#Synchronization|below]]
* Now all required parameters (camera optics parameters and synchronization frames) are defined for all source videos.
<center>[[File:build-combined-video-workflow.png|900px|link=]]</center>
* Evaluate background:
** using markers '''(6)''' and '''(7)''' select an interval on the timeline where there is no actor and moving objects (the length of this interval should be about a couple of seconds)
** alternatively, to set an interval on the timeline you can use controls in section '''INTERVAL''' of the toolbar — '''(8)'''
** click '''Evaluate Background''' button in the toolbar to evaluate background for all cameras simultaneously from the selected interval on the timeline — '''(9)'''
** alternatively:
*** you can evaluate background for each camera separately using button '''Edit...''' in section '''background''' in the left panel '''(3)''' — '''(A)'''
*** or you can even load background from file if you've already evaluated it before from different video — '''(B)'''
*** for details see [[#Background|below]]
* Now everything is ready to be saved into destination [[.iPiVideo File Extension|.iPiVideo]] file:
** using markers '''(6)''' and '''(7)''' on the timeline or controls '''(8)''' in the toolbar, select an interval you want to save to a resulting video
*** for a calibration video it could be an interval where the glowing marker is visible
*** for an action video it could be an interval with needed action sequence or movement
*** or you can save the whole video if you're not sure which exact interval will be used for processing in [[iPi Mocap Studio]]
** click '''Save Combined Video''' button in the toolbar and choose destination file name — '''(C)'''
** also before saving you can set compression quality for destination video — '''(D)'''
*** but in most cases the default value (70%) works very well providing a good balance between image quality and size of the resulting video
* Finally you can open the resulting [[.iPiVideo File Extension|.iPiVideo]] file in [[iPi Mocap Studio]] and process it.

== Important Aspects ==

Now let's discuss some aspects in details:

=== Cameras and Their Parameters ===

# It is strictly mandatory to add cameras in one and the same order for scene calibration and action videos. In other case results of scene calibration will not match action video(s). By the way, you can use drag-and-drop to reorder cameras in the builder.
# Don't forget to apply camera parameters by loading them from appropriate '''.iPiCam''' file. Remember that this '''.iPiCam''' file must be for this specific camera and for exactly the same resolution and view/FOV settings (FPS may differ). The thing is that camera optics parameters significantly vary from item to item (even when all items are of the same make and model) and depends on resolution and view/FOV settings.
# You can adjust [[How to Calibrate Camera Optics#Undistorting and Scale|the scale of undistort filter]] right in '''Combined Video Builder''':
<center>[[File:build-combined-video-scale.png|300px|link=]]</center>
:: Be aware that the same scale value must be used for scene calibration and action videos (per camera, of course). For this reason use this feature with a great care.

=== Synchronization ===

To build a combined video, source videos from individual cameras must be synchronized:
<center>[[File:build-combined-video-sync-schema.png|1000px|link=]]</center>

To do it, '''sync frame''' must be defined for each camera. '''Sync frame''' is an frame with some short and sharp visual event. For details see [[How to Record Video with Action Cameras#Synchronization Event]].

Example of synchronization using an external powerful on-camera flash:
<center><table border="0">
<tr><td></td><td align="center">'''Prev. frame'''<br/>(before sync)</td><td align="center">'''Sync frame'''</td><td align="center">'''Next frame'''<br/>(after sync)</td></tr>
<tr><td>cam1 </td><td>[[File:frame-before-sync-cam1.jpg|320px|link=]]</td><td>[[File:frame-sync-cam1.jpg|320px|link=]]</td><td>[[File:frame-after-sync-cam1.jpg|320px|link=]]</td></tr>
<tr><td>cam2 </td><td>[[File:frame-before-sync-cam2.jpg|320px|link=]]</td><td>[[File:frame-sync-cam2.jpg|320px|link=]]</td><td>[[File:frame-after-sync-cam2.jpg|320px|link=]]</td></tr>
<tr><td>cam3 </td><td>[[File:frame-before-sync-cam3.jpg|320px|link=]]</td><td>[[File:frame-sync-cam3.jpg|320px|link=]]</td><td>[[File:frame-after-sync-cam3.jpg|320px|link=]]</td></tr>
<tr><td>cam4 </td><td>[[File:frame-before-sync-cam4.jpg|320px|link=]]</td><td>[[File:frame-sync-cam4.jpg|320px|link=]]</td><td>[[File:frame-after-sync-cam4.jpg|320px|link=]]</td></tr>
</table></center>
<center>''(In the 3rd camera the flash is not visible directly, but you can see illumination it produces.)''</center>

Starting from version 4.2.0 of [[iPi Recorder]], '''Combined Video Builder''' supports two approaches to synchronization:
# fully automatic synchronization based on detected illumination produced by an external powerful on-camera flash
# manual synchronization based on any short/sharp visual event visible in all cameras simultaneously

==== How to synchronize automatically ====
* Just click '''Sync by Flash''' button in toolbar.
* In case of any troubles with automatic synchronization, you'll get appropriate message.
* In case of success, it is recommended to check synchronization (visually, approx.) to be on safe side.
* Also, you can see all detected flashes and selected '''sync frame''' for each camera on '''SYNC FRAME''' tab (click '''Edit...''' button in '''sync frame''' section of the left panel to call this tab):

<center>[[File:build-combined-video-sync-detected-flashes.png|600px|link=]]</center>

On this screenshot:
* '''(1)''' and '''(2)''' — detected flashes
* '''(3)''' — sync frames
* '''(4)''' — buttons for jumping to next/prev nearest frame with flash detected
* '''(5)''' — button to run automatic flash detector (for .iPiVideo files converted from regular videos like avi/mp4/mov, this detection takes place during conversion procedure).

==== How to synchronize manually ====
For each camera:
* Select a camera and click '''Edit...''' button in '''sync frame''' section of the left panel — see mark '''(1)''' on the screenshot below.
* Additional tab '''SYNC FRAME''' opens containing only video from selected camera.
* Using the timeline '''(2)''' choose a frame with synchronization event.
** it is convenient to use buttons '''Previous Frame''' and '''Next Frame''' to position precisely on required frame — see marks '''(3)''' and '''(4)''' on the screenshot below
* After that click '''Set to Current Frame''' button in the toolbar — '''(5)'''.
* Now switch back to '''BUILD''' tab by clicking on it — '''(6)'''.
* Also, you can adjust synchronization frame right in the builder using buttons '''(7)''' and '''(8)'''.
* Alternatively, you can set a synchronization frame to the current frame shown in the builder using button '''Current Frame''' — '''(9)'''.

<center>[[File:build-combined-video-how-to-set-sync-frame.jpg|1000px|link=]]</center>

=== Background ===

And the last but not the least thing in the way to combine video is background evaluation. Background is an image of clear scene without actors and moving objects:
<center>[[File:action-cameras-background-yes-and-no.jpg|1000px|link=]]</center>

There are three ways to evaluate the background:
# Simultaneously for all the cameras
#* this method is the easiest and described above in section [[#Overall Procedure]]
#* but it requires that clear scene is simultaneously visible in all cameras which can be problematic to achieve in real life conditions
# For each camera (source video) separately
#* select required camera and click '''Edit...''' button in '''background''' section of the left panel — see mark '''(1)''' on the screenshot below
#* additional tab '''BACKGROUND''' opens with a video from selected camera only
#* using triangles '''(2)''' on the timeline or controls '''(3)''' in the toolbar, select an interval on the timeline where there is no actor and moving objects (the length of this interval should be about a couple of seconds)
#* after that click '''Evaluate Background''' button in the toolbar — '''(4)'''
#* optionally you can save the result (evaluated background) to a file on disk to use later with different videos (see below) — '''(5)'''
#* now switch back to '''BUILD''' tab by clicking on it — '''(6)'''
#:<center>[[File:build-combined-video-how-to-evaluate-background.jpg|1000px|link=]]</center>
# Or you can evaluate background based on other video, save it to a file and then just load it when you need the background for appropriate camera.

In any case it is worth to check the background quality after evaluation using '''Hide Background''' button in the toolbar of '''Combined Video Builder''':
<center>[[File:build-combined-video-hide-background.jpg|753px|link=]]</center>
<center>''(In this particular case background subtraction is not ideal but good enough for motion capture needs.)''</center>
