30P is great for sports, music videos, DVD delivery, web delivery, etc. It is NOT good for going to PAL, dropping in a 24P timeline or a film bump. It CAN be done but gets messy. For the record, the XL2 does true 30P, not the frame mode...

I still want to know, does 30p uprez if you are using an upconverting DVD player that uses the faroudja chip set for instance?

Paul Leung June 30th, 2006 05:09 PM

yeah, I want to know how to make a 30P DVD as well. Do we have to trigger the progressive flag like 24p dvd when doing the compression?? I don't understand how we can play 30P videos smoothly with an interlaced tv.

All you need to do is tell the mpeg encoder you are using that the material it 29.97 but progressive, not interlaced.

I just took a job were I am shooting 30p. The subject matter is mostly stand up presentations were 24p wouldn't look right. 60i looks like everything else out there so I went with 30p. The last project I did like this got the "that looks really professional" comment in regards to the video quality.

DVD doesn't support 30p. But 30p in a 60i stream still looks like 30p.

Thanks David.

Does it mean that there is no difference to the viewer whether I flag the video as progressive or not as suggested by Bennis? I filmed and edit a travel video in 30P last year. However, the video is very jerky when viewed on TV.

The jerkiness could come from any number of factors, mostly in your render. If you watch your original tape on a TV, you're watching it in a 60i stream. If it looks fine from the tape, then the source video isn't the problem. Could be bad compression.
