Video Record Page
To capture a video stream press the Record button on the Toolbar(See 2.2.2).
NOTE: If Capture to RAM is unchecked, video is streamed directly to disk. The performance will depend on the speed of the hard disk and could result in dropped frames.
NOTE: The video formats are uncompressed and will take a significant amount of hard disk space.
NOTE: If Preview is disabled then the Color Pipe functions are skipped while live frames are accumulating. There will be no AE, nor any other Color Pipe processing.
You can save data in MPEG-4, AVI (2GB limit), WMV, or RAW format. RAW format requires no image processing and usually takes less disk space. If you don't have a compatible WMV codec installed, you'll be prompted with a URL to download one when you select that format.
You can also save data as "PNG Raw Files" or "PNG RGB Files", which is the ability to save a video as a sequence of PNG files in either Raw or RGB format. Note that Raw only supports Bayer or similar (not YCbCr).
You can use WMV instead of AVI for unlimited file length. DevWare does not use compression with AVI. Usually the codec is just RGB-24. WMV is compressed in software.
The compression quality for MPEG-4 or WMV recording can be controlled with the "VidCap Quality" STATE variable
RAW video files of 10-bit, 12-bit or 20-bit pixels are packed to conserve space. 10-bit is packed four pixels to five bytes, 12-bit is packed two pixels to three bytes, and 20-bit is packed two pixels to five bytes. The packing is like this:
