I have been using an M1 Mac Mini to compress blu-ray mkvs.
I have been using a X265 lately. I had an error with one file and came to site and saw mention of VideoToolBox, so I read the faq and decided to try it.
VideoToolBox is massively faster.
Here are my settings: (both: mkv, frame rate: same as source, tune: none, level: auto)
X265 H265 10bit 20RF, slower, 15-20fps, generally over 2 hours to complete.
VideoToolBox H265 10bit, 20 CQ, quality preset, 250fps, about 12mins.
this test is with no filters, but I do use Denoise: HQDN3D Medium to reduce files size on grainy videos regularly.
My question is, what if any are the quality differences or anything I need to be aware of?
why wouldn't all Mac users use videotoolbox?
is there a reason why there are no presets made for videotoolbox?
I quickly looked at parts of the test video and it looks near perfect to me.
thanks to all the devs that make handbrake!!!
