FastFlix VS QSVEnc

Oh, I've used QSVEnc by Rigaya for fastflix. That's good that Rigaya had done that then.

Yeah I’ll for sure check out fastflix I think they have Nvidia AV1 although you need to add this to the settings so it can be used. Though I don’t know enough about the dual Nvenc encoders unfortunately. Though it’s worth a try to use.

I've been ripping my 4K movies again (to transcode them again using FastFlix, which I heard actually supports 10-bit HDR, unlike HandBrake), and I've noticed MakeMKV failed to rip a few of my 4K discs at some point, even though I had tried to clean the bottom of the disc several times. "2001: A Space Odyssey", "Back to the Future Part 3", and "Star Trek: The Motion Picture Director's Edition" started to rip but then failed. With Back to the Future 3, I remember MakeMKV saying it was a hash check failure or something similar (it was enough to make MakeMKV stop ripping it and fail).

If you have something reproducible and know it's an issues with FastFlix would love an issue on github https://github.com/cdgriffith/FastFlix/issues !

For GUI (shameless self plug) FastFlix wraps around it to make life easier https://github.com/cdgriffith/FastFlix

Well i have to recommend FastFlix as I literally coded it lol. It wraps around ffmpeg as well as Rigaya's hardware encoders (have to download and link them in settings panel).

Have you looked at rigayas hardware encoders instead of ffmpeg to see if issues is also present in QSVEncC ? https://github.com/rigaya/QSVEnc

Not quite what you asked for but I would highly recommend Rigaya's hardware encoder with AV1 support. Has more features (like hdr10+ / dolby vision) and I like using them more. https://github.com/rigaya/QSVEnc

I ended up playing with rigaya's QSVEnc (or NVEnc) and got it working for HEVC, for example using the "--master-display" flag, but according to the documentation this doesn't work with AV1 yet. https://github.com/rigaya/QSVEnc

But I actually got through it and found a great solution for myself using StaxRip and an updated QSVEnc by Rigaya. Replace StaxRip's outdated QSVEnc with the updated Rigaya QSVEnc.

The only one I know of that can take advantage on Intel's hardware av1 encoder currently is qsvenc, which is some random Japanese encoder that I'd never heard of until recently.
