DGPulldown changing movie length...Help!

[BerserkerTails]

Okay, so I've been following FulciLives' PAL to NTSC guide, which is a godsend, but I've come to a critical error right near the end. I've ran my movie though TMPGEnc and now have the NTSC size but 25 fps video. I've run it through DGPulldown twice, using the 25 -> 29.97 option, yet each time I do, the movie gets about 20 minutes shorter, thus making the audio out of sync.

I've opened up both the movie.m2v (Before pulldown) and the movie_pulldown.m2v (After pulldown) in VirtualDubMod, and the lengths are indeed 20 minutes off. The movie.m2v is the right length, 1 hour, 49 minutes and 3 seconds, but the pulldown one is roughly 20 minutes shorter. I'm sure I've followed the guide exactly, so could anyone have any ideas about what's causing the problem?

The movie itself was progressive, if that makes any difference at all.

Any help would be much appreciated, thank you!

Is the output running faster, or being truncated ? While pulldown should not actually change the running time, even if it did cause the movie to play back at 29.97, this would not account for a 20 minute difference over such a short source file.

So check the output and make sure that it is all there. Also, try opening it in virtualdubmpeg2 and looking at the framerate that it shows. I suspect you have a fundamental problem with your source somewhere.

Hi-

I've opened up both the movie.m2v (Before pulldown) and the movie_pulldown.m2v (After pulldown) in VirtualDubMod, and the lengths are indeed 20 minutes off.

Since you followed his guide, you have DGIndex also. When you open the before-pulldown M2V and run the preview, the framerate says 25fps? And when you do the same with the after-pulldown M2V, it says 29.97fps?

...thus making the audio out of sync.

Have you actually muxed/authored it yet to confirm out-of-synch audio?

And for the 64 thousand dollar question, when creating the D2V in DGIndex, are you sure you used "Honor Pulldown Flags" instead of "Forced Film"?

Okay, so when I opened the pulldown file with VitrualDubMpeg, it told me it was the right length. I tried muxing it, despite it looking out of sync, and it worked flawlessly. So it turns out I did everything right, I just need to find better authoring software, haha. (I use DVD Composer, just incase anyone was wondering)

Thanks for the help guys, even though I didn't really have a problem.
