Creative Labs YUVOriginally designed for the Creative Labs Video Blaster, the Creative CYUV video codec stores frames in a DPCM coded YUV411 format. Encoding and decoding of frames was originally performed by the vblaster.drv Windows driver. This codec looks to have been designed for simplicity and speed.
The CYUV codec is a very simple predictive coder. A video frame is coded in the YUV colour space, with the chrominance components subsampled by four in the horizontal direction (YUV411).
