Roto Question for 25 fps footage converted to 29.97
I’ve been given an NTSC digibeta of some footage that was origianlly shot in Europe as PAL, but then converted to 29.97. I’ll be doing some tracking and roto work. Normally I receive footage that was telecined from film so I’m used to removing pulldown and then doing my comp work in AE at 23.976. However, what is the process for working with 29.97 footage that originated at 25 fps? Removing pulldown obviously won’t work and I’m wondering if there’s anyway I can work on full frame images in AE. Any info is greatly appreciated.
Thanks,
Mike -

Depends on how the video was converted to 29.97.
Was it sped up to 24 frames per second and then telecined?
Can’t undo what you don’t know was done.

I’m assuming it wasn’t sped up to 24 and then telecined because none of my pulldown removal options provide me with a solid frame. I’m getting a lot of interlacing and frame blending no matter what cadence I use. What might be another process they used in converting this footage from PAL to NTSC?

I just had to do this for a DVD extras feature.
What I did was bring the footage in, with fields separated but WITHOUT any pulldown. I put this in a 59.97 comp. I then nested this comp in a 25 frame per second comp.
Sometimes I got lucky and it lined right up. But depending on what point the digitizing started, I had to nudge the footage in the 59.97 a frame or so forward in time.
It helped that the footage had keycode burned in.

59.94, right?

I need to go back out to 29.97 though. If I precomp at 59.94 and then comp at 25, what’s the best way to go back out 29.97? Should I just drop my 25 comp into a 29.97 comp and render?

woops 59.94… right Steve.
And Michael, you could compify again into 29.97, OR just set the render of the 25 fps comp to 29.97 interlaced.
