Re: composing for video

[Danni Coy <danni.coy@xxxxxxxxx>]

You would be suprised. RGBA32 is used quite commonly in the compositor world, usually stored as a sequence of images, with even higher precisions available. Raw RGB24 is reasonably common with the video professionals I know, when I questioned them about it they said that they could acheive more film like colour grading than they could in any of the YUV colour spaces. 

It's probably not the best format for realtime work given the amount of data that needs to be transmitted (or maybe it is), I have previously worked with piping raw YUV (yuv4linux) between applications and having something like jack to manage the connections would be a godsend.

Why RGBA32 RAW? Who in the professional video world would use such a format?
