[MEncoder-users] Audio/Video desync during conversion by mencoder

[Florian Sollinger]

Hi!

I'm a newbie myself, so let's see if I can help you...

[trying to rescale a Matroska video]

Sure you want to copy your Matroska File into a AVI Container without 
re-encoding?

> mencoder -o converted.avi -oac lavc -ovc lavc -vf scale=400:-2 original.mkv

As far as I can see this will use the MPEG2 audio codec and the MPEG4 
video codec. Is this what you want?

The rescaling is not the reason for the sync problem. It must be because 
of the re-encoding.

Another idea: Already tried the harddup option (-vf harddup,scale=...)?
