Changing Framerate AFTER Exporting - Audio Sync Issue

Postby Angelyco » Fri Oct 16, 2009 8:17 pm

I wasn't sure whether to put this in this forum or the Audio forum, but here we go:

I'm working on a track for an MEP that requires 23.97 fps. I edited the project at 29.97 fps, since I was able to reuse a ton of clips I already had prepared from a different project. When I went to convert to MP4 with the ZarxGui, I changed the framerate in the script, but I forgot about how that would effect the audio. After I realized what I did, I used BeSweet to change the audio framerate to 23.97, and now it sounds AWFUL. I definitely can't use it like that.

I really don't want to have to redo all the clips and redo the entire project at 23.97, is there any other way to change the framerate and keep the audio intact and in sync? Any suggestions would be more than welcomed.

Thanks, I did read that one already but it wasn't quite what I needed. Going from 30 to 29.97 isn't so bad to change the audio framerate for, but this is too big of a change for the audio.

Let me understand: you have a 29.97 export and want to make it 23.976?
Code: Select all
tdecimate()

But how will that affect the audio sync?

It might be one frame off in some places. That's about it. No speed change tho.

WOW that worked! Not even a single (noticeable) frame out of place.

Now that I think about it, that function makes sense, since it's getting rid of the extra frames instead of just slowing everything down.

Thanks so much Mirko, you're turning into my hero :)
