Hi I was wondering if somebody could help me.
I have two versions of the same film, one with good video, one with good audio.
MediaInfo tells me they're both 25 fps. Yet, it seems as though the audio tracks' frame rates are different, as when I muxed the video from one to the audio from the other, the audio begins in sync, then steadily gets worse, as one would expect when the frame rates are not the same.
Can anyone help explain this, and help me combine the video and audio tracks with them in sync?
Below are the details from MediaInfo for the two files.
I want to use the video if the below file, which has great video but the audio track has a Russian interpreter dubbed over the original Italian AC3 track, so it's useless.
So I want the video from this:

lengths don't match 2h24 vs 2h34
154 min vs. 144 min isn't the same ratio as 25 / 23.976 so they could be different cuts, different theatrical releases, etc.. -
Oh - I was wondering about that, too - but wasn't sure how to calculate whether it was a frame rate issue.
Darn - they may well simply be different cuts. Though I was sure there was only one.
Thanks for you response, poisiondeathray. -
Do you understand what I'm saying? If it was a simple PAL<=>NTSC issue, the difference multiple would be ~1.0427 (Pal framerates are 25, Film framerate is 23.976 ) . The Pal version should be shorter in duration because it runs 25fps .
If it was that simple issue, then you could speed up or slowdown either the audio or video to match. This is very common and easy to fix. Programs even have presets to do this sort of thing
You probably have extra stuff in one , like more credits or extra scene
The only way to know is to line them up in an editor and compare , trim out the extra stuff
Probably be easier to rip the original source.
