Theora's own quality CRF goes from 1 to 10, with higher being better quality.

I haven't used Theora a lot so I can't really say much about it. Historically, it competes with [[x264]] and [[Xvid]].

==== ffmpeg ====

Use ''qscale'' to set CRF.

<code>
ffmpeg -i dvd_track.mpg -codec:v libtheora -qscale:v 7 video.ogv
</code>

==== HandBrake ===

HandBrake accepts quality CRF from 1 to 63, with default of 45.
