This codec is very similar to JPEG. Every frame is independent and consists of VLC-coded DCT coefficients.

Header consists of many parts and may include quantization tables and 2048 bits of user data. Also each frame has two GUIDs and timestamp. All header is packed into big-endian dwords.

Actual frame data consists of packed macroblocks with technique almost identical to JPEG: DC prediction and variable-length codes with run length encoding for other 63 coefficients.
