So it seems mencoder can just drop video frames.
That's good to know. For references sake, what was the commandline that
you ended up using?
I wrote it in another post in this thread already, but here it is again:
1) Figure out the position at which the offset starts using mplayer.
2) Get the faulty part in a separate file, delay audio as necessary:
mencoder -ss 02:47:55 -oac copy -ovc copy -delay -9.55 file.avi -o
fileb.avi
3) Get the good part into another file:
mencoder -endpos 02:47:55 -oac copy -ovc copy file.avi -o
filea.avi
4) Put the parts back together again:
mencoder -oac copy -ovc copy filea.avi fileb.avi -o
filefixed.avi
filefixed.avi is the resulting fixed file.
What I noticed though is that it's limited in granularity, maybe it has
something to do with keyframes. In my previous case I had 13 seconds cut
out instead of 9.55, but it seems like it can be more. I know far too
little about video or mencoder to tell what's really going on.
Well, it's ok for me to loose a couple of seconds and have synced audio.
I suspect you're not the only person who feels this tradeoff is a
reasonable *default* choice.
It's functionality like this that could be relatively easily added to
existing software and would make a huge difference to a lot of people over
the years. The problem is knowing how to achieve the goal and automating
that process. Seems like you have figured out a useful commandline method.
Hopefully that will get picked up and integrated into a GUI solution at
some point.
