Hi, mates! Need help here:
I've got two different versions of the same material, encoded in differrent software/hardware/parameters and time in the past. Don't have original anymore.
Well, now I'm trying to create a third version w/ video from Version1 and audio from Version2. Result: audio synching issue!
See attached the properties of the two files.
Thanks in advance!!!

How is it out of sync ? Constant offset? Progressively worsening ? In and out of sync ?
In theory you should be able to use mkvtoolnix, load the videos, checkmark streams you want, uncheckmark streams that you don't want
But version2 is variable frame rate according to mediainfo - that might give you problems. You might have to play with timecodes or check the video frames and audio duration more closely
I think you're right: variable frame rate of Version2 is the problem. I have never seen it! All methods I tried gave me out-of-synch result. And it's not time shift or duration issues.
How do I deal w/ timecodes?
I'll try, thanks! Little busy now, but will post results here.
