23.976 fps to 29.97 for DVD

[joshbm]

I have a film 23.976 fps (progressive) video and would like to put it on a NTSC DVD (29.97 fps - progressive). How would I do this? I really know very little about telecine and inverse telecine.

Just run pulldown on it:

It will add flags to the stream, so that it is played back at 29.97 fps.

Wilbert,

Thanks for your reply! What are the specifications that I need to encode my MPEG-2 file at? Because I remember trying to run it through a pulldown process before and it gave me an error when I tried to import it. Something about GOP's?

PS- Does that utility have support via the command line?

I use Ulead Media Studio Pro and it can do a 2-pass VBR, but it cannot modify advanced things such as GOP structure. So I will probably move to TMPGEnc. Now, if I recall there is a 3:2 pulldown checkbox within TMPGEnc, so there is no need for an external utility such as DGPulldown, correct?

That's correct. It's called 3:2 Pulldown when playback. Frame rate must be 23.976fps (internally 29.97 fps)

You didn't tell us what your source file is...is it M2V video (from a DVD) or an AVI file with a 23.976 framerate?

You said it was progressive, so chances are it's an AVI (a lot of DVD's I have are interlaced, especially a lot of the PAL ones).

DGPulldown will open an M2V file (Progressive MPEG-2 video stream) and alter the flags to make it play at 29.97, and this is generally the last step before you build your DVD files (i.e. if you have your AVI, make your MPEG-2 file first and then apply the pulldown, make sure your MPEG encoder (TMPGEnc, Qenc or whatever) is making a progressive MPEG-2 file and not adjusting the framerate)

There are conflicting views on whether the 3:2 pulldown in TMPGEnc works correctly, but DGPulldown does for sure, and it takes only a few minutes. It will also work on 25 fps files if your original was PAL or from a video camera.
