How do you count field pictures?
It's a good question. Is there a way to indicate that raw video is interleaved fields and not frames? Michael?
There are (at least) three cases to consider:
1. Progressive frame pictures. 2. Interlaced frame pictures containing interleaved fields. 3. Field pictures containing only odd or even lines.
For case 2, the field order must somehow be signalled.
I've never heard of anything using more than two fields per frame, and I hope I never will.
Indeed, I can't envision someone creating NEW evil forms of interlacing, just struggling to hold onto the existing ones for irrational reasons... Rich
