Side tangent here, do modern video cameras have an equivalent to RAW for picture cameras? I know there are lossless codecs used for preserving quality while editing, but I've never looked to see if that is to preserve the existing compression quality coming in from the camera, or if it's to preserve the uncompressed level while applying some data reduction.

The Red cameras appear to do lossy compression, but not sure if these are truly representative of what one might find across the board.
