[HELP] New to Hybrid - basic x265 encode abnormaly slow
#1
Hi Selur!

I'm new to Hybrid and exploring it, looking for more flexibility with denoising filters and the possibility of using QTGMC with CUDA eventually, etc.
I've started with a very basic x265 CRF20 slow preset encoding on a 4K HDR/DV source, without any filters activated, nothing else, and I'm surprised to have ultra slow fps (like 1-2 fps...).
Even the projected bitrate is crazy high, like 28000-34000kbit/s.  It was as if a placebo was selected!

When I run the same test with the same x265 settings using other tools like Staxrip or Handbrake, I get between 5-10 fps, bitrate 17000 kbit/s.

Note: I have a Ryzen 9950X3D + RTX 5080 - Windows 11, 

Obviously, I'm missing something.

Do you have any ideas of what I could be missing? Sad

If you use the same setting without any Vapoursynth or Avisynth filtering both StaxRip and Hybrid would be the same speed with Vapoursynth, Hybrid can be faster depending on the settings.
=> your settings must differ

Dev versions are in the 'experimental'-folder of my GoogleDrive, which is linked on the download page.
