I read here (http://tuxrip.free.fr/faq_en.html) that when encoding to xvid, having a qf over 0.30 is overkill and 0.20-0.22 for 1CD and 0.26-0.28 for 2 CDs is optimal (quality/size). What is a good qf to shoot for when encoding to x264?

A "good" starting point would be QF(xvid) * 3/4. But beware of QF : It doesn't take the complexity of the movie into account, and that matters a lot. Furthermore, it doesn't take subjective tastes into account. For example, I tend to prefer a large resolution with some artifacts, than a smaller artifact-free resolution. Other people can't tolerate any artefacts. All that to say you'd better make some tests on your own.

QF simply means nothing... do a real comp.test if you are concerned about quality...

I'm sorry for bothering you, but when I wanted to send you a PM, it came back with this error:

Sharktooth has exceeded their stored private messages quota and can not accept further messages until they clear some space.

Maybe you have the quota exceeded on purpose, but if this is not the case, you might want to know.

Others please don't be :mad: at me, I don't know where to post this.
