Encoding to HEVC, what to use?

hyperseven · 17 Jan 2016 at 17:49

Want to re-encode some films to reduce file size side my dads tablet is only 16GB and has no microSD slot.

What software is any good for this task, preferably with CUDA acceleration.

x265 - Handbrake.

doesn't seem to use hardware, GPU, acceleration only CPU.

True. I know of no CUDA-based x265 encoders but if you require assured quality then x264 and x265 encoders are your best choices.

These days it appears that Nvidia is more focused on its NVEnc hardware encoder solution, although this is more tailored for online streaming rather than quality video capture.

cheers, I give it a go on a folder of films, have 8 oc'd threads going at it so it should be OK.

Handbrake is the fastest seen it use 32 cores in person great software

Mind blowing app ,

https://github.com/stax76/staxrip/releases
with NVENC Hevc hardware acceleration using cuda
on gtx 980Ti 1080p 30 minutes movie has been encoded to Hevc within less than 15minutes

You'll only get about a 25% reduction in file size between x265 and x264 (for example). Surely not worth the faff of re-encoding?

NVENC is probably your best bet.

I've used the nightly builds of Handbrake and quick sync to hardware encode using the GPU in my CPU
