Vapoursynth can handle high bit depth way better than Avisynth and is faster for multi core systems (4+ cores).
Since your encoding is already so slow Vapoursynth might not be an improvement.

Only way to speed things up on your hardware is probably to use a faster preset.

i use Avisynth for encoding i never use Vapoursynth before

yeah put it in hibernation mode is the only best thing.
thx man!

RE: hi - encoding really slow - x265 - 01.02.2018

Hi selur. I have a laptop with i7 3678u cpu. Will the encoding process be faster with this cpu if i use vapoursynth instead of avisynth?

RE: hi - encoding really slow - Selur - 01.02.2018

Probably depends on the filters you use.
Vapoursynth has better multi threading support thus more cores help more, but for single threaded stuff it is sometimes slow.
-> best try Smile

RE: hi - encoding really slow - hbb - 02.02.2018

i'm having same problem here. getting average 20fps on 4k ending about 3 hours both nvenc gxt 1080 ti and p4000
does hybrid uses Vapoursynth by default? how can i check and how to speed up things?

RE: hi - encoding really slow - Selur - 02.02.2018

Yes, Hybrid uses Vapoursynth as the default fiter option.
I need more details. If you provide me with a debug output of a typical Job creation I can look at it an suggest possible speedups,...

where do i get that? is there a log file?
