Re: [Avid-L2] which seq to DVD

This is probably a good time to ask; does anyone know of a 'compression cookbook' that's relatively up-to-date? I currently export pretty much everything as H264, with only the occasional client who says he can't open it, but there are probably other codecs that would work better under certain circumstances/on other platforms, etc.

I have a compression book kicking around, though it's about ten years old, and probably a little dated now.
