I think this also goes for the ffmpeg encoder, i.e. tweaking some flags
has great impact on quality, but makes the encoder somewhat relatively
slower. I know I had some tests done by one of the developers over at
ffmpeg-devel at one time, but seem to have lost them, I bet a
`performance test`|`quality test` query on the ffmpeg-devel list archive
would reveal them though.
