-------------------------------------+-------------------------------------
When converting to webm with a "-q 9" argument, avconv instead uses the
lowest quality conversion. As it is encoding, it says "q=0.0" and the
resulting file is small in size and has bad quality.
"avconv -i vid.mkv -q 9 vid.webm"
