CRF Slider - Half Steps

Post by Bjomesphat » Sun May 12, 2019 5:41 pm

A few weeks ago there was a nightly build that introduced half steps on the constant quality slider (ie. 25.5, 26.5, 27.5). I ran some testing on it and it seemed like the half steps were giving me near identical quality as the full step right below it, but with slightly reduced filesizes. However, I just downloaded the latest nightly and the half steps are gone.

So was this a feature or a bug? And I'm curious why it's gone now.

It should be in the preferences.

Depending on which GUI you're using, x264 CRF granularity has been in the preferences for a long time, and wasn't "just introduced".

Ah, that's what granularity means. I've been using Handbrake for years, but never bother to look into that setting.

I'm glad that Nightly defaulted to .5 for whatever reason, because I'm finding it very useful. Thanks all.
