Re: VB: Film for DVD
The real killer in DVD land is that it is a 4:2:0 vertical compression scheme so any real advanage of progressive vs. interlace is gone in the compression pass. I would guess that it looks better on the PC display because of the higher refresh, not because it is a native progressive format.
This brings up the issue of broadcast DTV vertical compression. Is it 4:2:0 also? or is someone planning ahead and forcing 4:2:2 into the picture (so to speak) Is the bit rate so valuable that 4:2:0 pays off in overall picture quality and therefore we let vertical resolution slide???
Hmmm, I wonder?

Thanks to Kodak for support in 1998.
