- You mention the preferred resolution and audio sample rate, but are there any restrictions on frame rate?
- For MPEG-1/-2 files, are both interlaced and progressive acceptable?
- For MPEG-2 files, is 23.976fps with the "3:2 pulldown upon playback" flag acceptable?
- For MPEG-2 files, is the anamorphic 16:9 flag acceptable, or should we encode a widescreen AMV as 4:3 letterboxed?
No matter what I am sent, it all gets stuffed into a DVD sausage - take that into consideration. Make it progressive, don't feel like de-interlacing your old DVD footage, and anyway, who the hell submits an interlaced video digitally? Frame rate is no big deal, but I will probably shove it all down to 29.97, so if you're worried that your video will look janky given my conversion, give it to me at that rate. I'm not playing it back off of an MPEG playback card or anything, so bear that in mind.
I get so many different formats that I end up having to make compromises in the content each year, but it is safe to send 16:9, as I prefer to have a timeline in 16:9. Think about it logically, though, like if you were running a contest - if you get some 16:9, some 4:3, what do you do? Hint: The answer is that you don't try to shoehorn 4:3 footage into 16:9 frame, you shoehorn 16:9 into 4:3.
Also, correcting the grammar of posted contest rules does not ingratiate you to judges. For the record, nowhere in the rules does it say your video will be judged independently of estimations of your politeness.
