I completely agree with you. But let's not forget another key factor: the size of the resulting file is 2 to 4 times smaller.

I don't agree with your opinion.
Is it based on your experience? Or just theoretical knowledge?
Because my experience says otherwise...

Re: H.265 (AMD VCE) encoding problem

Hi.
After installing the Radeon latest drivers (v.19.4.1) the average FPS has dropped to 80 f.p.s.
I needed to go back to the previous version (18.5.1) in order to keep above 300 f.p.s.
I suppose that some internal change in the code does not allow HandBrake to work so efficiently.

Re: H.265 (AMD VCE) encoding problem

I'm impressed by the work with my RX580 from the latest release of HandBrake (1.2.1). It seems that all the previous problems have been solved, but in addition the conversions to H.265 using the AMD codec gets the 370 f.p.s. (H.264 to H.265 720p) on average. Not below 180 f.p.s. when I convert to H....

H.265 (AMD VCE) encoding problem

Description of problem or question: I have an AMD RX580 graphics card running with an AMD Ryzen 1700x. I encoded some video files with the new H.265 (AMD VCE) codec and I think I found a bug. The resulting files look perfect and the encondig times are now a third of what they were before (around 80...
