I have a 9.5 GB MKV file, and I want to convert it a mpg or avi file using AVConv.

How can I accomplish this?

  • see ffmpeg (which comes out of the box in Ubuntu 14)

  • first install "sudo apt-get install ffmpeg" then show the manual with "man ffmpeg"

avconv -i infile.mkv -c:a copy -c:v copy outfile.avi

This will not modify the quality.

avconv -i infile.mkv -c:a ac3 -ab 96k -ac 2 -c:v mpeg4 -s 640x352 -b 800k -bufsize 20M outfile.avi

This should change size to 'ripped' avi of medium quality (not tested).
