Hello I recently tried to reencode a certain video with the following command:

ffmpeg -y -i test.mkv -vf scale=720:-2 -c:v mpeg4 -vtag xvid -b:v 969k -pass 1 -an -f avi /dev/null && ffmpeg -i test.mkv -c:a libmp3lame -b:a 48k -ac 1 -vf scale=720:-2 -c:v mpeg4 -vtag xvid -b:v 969k -pass 2 output.avi

It apparently worked without any issues. Nonetheless, when I try to hear it, it became clear that the video-audio synchronization was gone for some reason.

And what is worst, it did not emitted any unusual messages. Usually when that kind of stuff happens, messages in red or yellow are printed in screen, but this time there is none related to audio.

So what can I do to solve the issue and to figure out the cause?

One possibly relevant observation is that the lack of synchronization seems to became worst as the video progress (not 100% certain about it)
