ffmpeg hq parameter

[pieroxy]

When transcoding with ffmpeg, I see that there is an option "hq" that can take the values: simple, rd or bits .

My question is simple: Which one will give the best results? There seems to be no documentation on this, but for listing the possible values.

Thanks

Will depend on the source! Play with it.

Thanks... but could we have at least a rough idea of the difference between the three?
