| + | ==== 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. | ||
