iPi Recorder Release Notes
Here you can find history of recent versions of iPi Recorder.
iPi Recorder has built-in auto update functionality. Auto update feature is configured so that checks for update are made once per day. It helps to reduce the start time of the application. If you want to update ASAP — you can use the Check for Update button on home screen.
Note that both of these features require Internet connection. Alternatively (in case of troubles with auto update), you can download and run the updated installation program from direct link.

N E W F E A T U R E S:
- Support for the new depth sensors:
- Intel RealSense D415 / D435
- Orbbec Astra / Astra PRO
- ASUS Xtion2
- Tool for precise calibration of cameras (this allows to determine camera internal parameters, including distortion)
- Powerful video builder, which allows to combine/edit video from different sources, (re)evaluate background, set/patch inter-cameras synchronization, etc.
- Support for workflow with action cameras like GoPro and Sjcam
- Real-time Tracking for Live Preview: live data streaming to iPi Mocap Studio
B U G F I X E S:
- Poor quality of Sony PS3 Eye video if Upside Down option set.
- Backround was not discarded in case of certain changes of the recording settings
ver. 3.3.2.57
B U G F I X E S:
- Сritical bug fix in depth sensors reinitialization after resetting of devices or returning from playback.
ver. 3.3.1.56
N E W F E A T U R E S:
- Workflow improvements for background evaluation in distributed recording:
- It is allowed to enter slave mode or connect to slaves without previously evaluating background.
- Running background evaluation on a master PC triggers evaluation on slave PCs as well. Thus there is no need to run background evaluation on slave PCs manually.
- Current percentage of background area is displayed in a status of a slave PC (minimum value among all cameras on this slave PC).
- Export of depth data from iPiVideo to series of PNG files. 16-bit grayscale colors represent depth values in millimeters.
- Note: For Kinect 2, a conversion table from depth space to camera space is exported into a TAB-separated text file along with depth data.
- Simple frame center marker introduced for alignment purposes has been replaced by a more useful alignment grid.
B U G F I X E S:
- Ensure PLAY tab is activated first when opening a record.
ver. 3.3.0.55
N E W F E A T U R E S:
- Improved performance with Logitech C922 cameras.
- Workflow for opening a record for playback from Recording Results dialog is improved. Instead of HOME button, there is a BACK button to return to recording without losing previous recording state (like evaluated background).
- Option to mark centers of camera frames on SETUP screen. This may help with positioning of cameras.
- Statistics overlay control is hidden the same way as other controls when collapsed to not cover the bottom area of a frame.
- Asking confirmation on closing the application when recording is in process.
- New event recording-started in Automation addon.
- Hover toolbar in Recent Records list. It was available as context menu (on right click) previously.
B U G F I X E S:
- Pressing PROPERTIES or CALIBRATE button in overlay controls now exits full screen mode automatically.
- Compatibility of supported compression modes is now considered when determining whether selected cameras are compatible.
- Fixed app crash when an error occurs on disconnecting web camera.
- Reset Devices command on RECORD screen now does not reset evaluated background.
U N D E R T H E H O O D:
- Using GPU (supporting DirectX 11) for rendering camera streams. This improves overall performance during recording.
- Improved performance of the Trace window.
ver. 3.2.11.53
B U G F I X E S:
- Calibration procedure did not finish with some PS Moves because they do not provide magnetic data. Now magnetic calibration can be skipped.

ver. 3.2.9.51
B U G F I X E S:
- Fixed app crash after background evaluation with Xtion/Carmine depth sensors.
ver. 3.2.8.50
N E W F E A T U R E S:
- Added support for 1280x720@90fps and 1920x1080@90fps modes of Logitech BRIO webcam.
- For depth sensors (Kinect, Kinect v2, Xtion, PrimeSense): checking floor detection quality during background evaluation, warning user about bad floor visibility.
- Making photo from web camera or depth sensor (copying of current image from video source to clipboard).
- Automation Add-on updated to manage Distributed Recording:
- Added discover-slaves command
- Added connect-to-slaves command
- Added disconnect-from-slaves command
- Added enter-slave-mode command
- Added exit-slave-mode command
- recording-stopped event has got a new argument slaveResults which holds some details about the results of distributed recording on slave PCs.
- Automation Add-on: ensure correspondence of devices/screens order in UI and items order in the result of get-devices-state command.
B U G F I X E S:
- Automation Add-on: argument selectedDevices of open-recorder command was ignored. Now it works and items order in selectedDevices defines devices/screens order in UI.
- Automation Add-on could hang in rare cases during events sending.
ver. 3.2.7.49
N E W F E A T U R E S:
- Added support for 1280x720@60fps mode of Logitech C922 Pro Stream webcam.
- Filtering out webcam device for Kinect v2 sensor which appeared after recent Windows updates. This prevents confusion when recording with a "Kinect" camera produces a video without depth data.
B U G F I X E S:
- Fixed incorrect handling of skeletal data while saving edited videos.
- Fixed storing of incorrect device parameters in record after hot-swapping Kinect v2 sensors while Recorder is running.
- Fixed some visual glitches of the ribbon in collapsed state.
- Fixed cropping of camera screens on window resize occurring under certain conditions.
U N D E R T H E H O O D:
