All I can tell you, in fact, all I WILL tell you, is that I've been able to go from this baseline in x265 v1.9:Ayoross wrote:I've done a few tests, and it seems the grain tuning increases the file size quite a lot. However, it clearly enhance greatly all details.

If I ever want a lower-quality smaller file, I turn the speed up faster. If I want a higher-quality bigger file, I turn the speed down slower. That's IT!
I'm happy with this "discovery". If you're not, don't use it.
