[FFmpeg-user] Syncing stereo videos - what method?

Thanx for your input. I did not know the -itsoffset flag.

I think my problem was that I was trying to save the recoding via the copy
class. What ended up working for me was this.

/usr/local/bin/ffmpeg -y -loglevel panic  -ss 1.161397 -i 3.mp4 -t 15 _3.mp4

I could not make the itsoffset flag do the trick.

Kind regards
