==== Framerate ====

It is recommended that you record all videos at maximum available framerate. High framerate helps reduce motion blur and capture fine details of the motion.

Maximum possible framerate for Sony PlayStation Eye camera is 60 frames per second. Sony advertises PlayStation Eye camera as capable of capturing at 120 frames per second but framerates over 60 FPS result in too much noise in PlayStation Eye camera sensor and are not usable for motion capture.

Framerate lower than 30 frames per second is not recommended for motion capture.

==== 4 cameras at 320 by 240 resolution ====

A dual-core CPU should be fast enough for recording a 4-camera video at 320 by 240 resolution at 60 frames per second.

==== 4 cameras at 640 by 480 resolution at 60 frames per second ====

A quad-core CPU is recommended for recording at 640 by 480 resolution at 60 frames per second. If you have a dual-core CPU you may need to configure a lower framerate and/or lower compression quality to be able to record video at 640 by 480.

==== 6 cameras at 640 by 480 resolution at 60 frames per second ====

A quad-core CPU clocked at 2.0 GHz (or better) is recommended for recording at 640 by 480 resolution at 60 frames per second. You will also need to get additional [[Cameras and Accessories#USB controllers|USB controller]].

==== USB controllers ====

All modern computers (e.g. dual-core and better) based on Intel, AMD and Nvidia chipsets have two high-speed USB (USB 2.0) controllers on board. That should give you enough bandwidth to be able to record with 4 cameras at 640x480 (raw Bayer format) at 60 FPS, or 6 cameras at 640x480 (raw Bayer format) at 40 FPS.

Under certain circumstances you may need to get additional [[Cameras and Accessories#USB controllers|USB controllers]].

 ==== Performance Tips ====
-Recording with multiple cameras is a very resource consuming operation. If the system does not provide sufficient resources, you may experience different problems like frame drops, unstable frame rate, premature ending of recording. All these end up in poor quality records that cannot be successfully processed in [[iPi Mocap Studio]]. Below are some recommendations which help you to avoid problems with hardware performance during recording.
