Pulldown 25fps to 29.97fps possible????

[durieux]

Hi

This a tricky one here....

I have been trying to encode frame based footage for NTSC & PAL. The source is a music video, now it seems that the original film footage was shot with TV in mind because the video footage derived from that film is at the right pitch and the right length when played in PAL at 25fps. So encoding it in PAL isn't a problem at all, on the contrary it's even better than having a film at 24fps speeded at 25fps because you get the right pitch & length.

No converting this to NTSC is very tricky because even though I could convert the footage back to 24fps progressive and run a 3:2 pulldown with rrf flags (Which does work), the audio is then too slow and too long (Although the pitch can be corrected).Does anyone know if there a way to encode 25fps progressive source and add pulldown flags so the DVD player playback at 29.97 fps???? Now that wouldn't be a 3:2 pulldown per se but a pulldown noneless. Pulldown.exe doesn't seem to be able to perform this...

Sorry for the long post but I thought this is an issue that's never been addressed... Thanks in advance in anyonme can solve this!

durieux,

Found this site with a guide that could help you. You need Adobe Premiere and a lot of space on your harddrive as what I read though.

You could probably do this with a frameserving script that counts two frames, then splits the third and fourth frames, then creates a frame between them with the top field from the third and the bottom field from the fourth (or vice versa), then repeating this pattern once every five frames. This will give you the 30fps that you need, then you could slow down the resulting video with an ASSUMEFPS(29.97) statement. This might be interesting to try.
