 +==== 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.
