iPiRecorder
For multi-camera video, you should use webcams (or other USB or Firewire cameras) and record a multi-camera video using iPiRecorder. Current release of iPi Desktop Motion Capture does not have other multi-camera options.
iPiRecorder works with Sony PlayStation Eye cameras and DirectShow-compatible webcams (USB and FireWire).
iPiRecorder is a stand-alone application and does not require a powerful video card. You may choose to install iPiRecorder on a notebook PC for portability. Since iPiRecorder is free, you can install it on as many computers as you need.
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.
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.
640 by 480 resolution
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.
Raw Bayer Mode
Sony PlayStation Eye camera supports special operation mode called “raw Bayer mode”. The name “raw Bayer mode” comes from the Bayer color filter array used in PlayStation Eye camera (filter array being named after Eastman Kodak researcher Bryce E. Bayer).
Raw Bayer mode is very efficient in terms of USB bandwidth usage and therefore is highly recommended.
Videos captured in raw Bayer mode look like multiple monochrome image planes. This is normal. You should not have any problems opening raw Bayer mode videos in iPiStudio.
