 +==== Encoding Quality ====
 +
 +With the defaults, vpxenc will create low quality encodes, its bitrate is too low. It will have to be bumped up to get some good quality.
 +
 +When using ffmpeg, pass ''-b 0'' (bitrate 0) so that it doesn't limit bitrate. Also use a CRF. For very high quality encodes, I'd say around 6 to 8.

 +<code>
 +ffmpeg -i video.y4m -vcodec libvpx -crf 6 -b:v 0 -y video.mkv
