[Avid-L2] Re: MPEG2 Q

Can DX Nitris Export MPEG2 or is that better done with Squeeze 6? I can also recapture into FCP. I'm not sure which gives the best MPEG2 results. Time for some testing I guess.

So 29.97p is actually 29.97PsF and 25p would be 25PsF. Two identical fields to look like a progressive frame, but that still fits into an interlaced signal.
