SVT-HEVC

SVT HEVC encoder. Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel® Xeon® processors. Using the open source SVT-HEVC encoder, it is possible to spread video encoding processing across multiple Intel® Xeon® processors to achieve a real advantage of processing efficiency.

I wrote a little script that uses ffmpeg with settings similar to those in the guide, and then another ffmpeg run to extract the subtitles as vtt. I would be happy to share more of my settings if you are interested. Of course, your needs and mine may differ.

How about use the parameter "HighDynamicRangeInput" with command line "--enable-hdr 1"? It's from the official page: https://github.com/AOMediaCodec/SVT-AV1/blob/master/Docs/Parameters.md

Seems like the SVT-AV1 documentation issue #1753 about missing presets explanation is fixed now. And it seems like the preset 0, 1 and 2 are the same thing. Plus tons of other useful encoding guidelines (like how to tune for animation etc.).

CTU sizes for HEVC_NVENC and libx265?
1 project | /r/ffmpeg | 24 Jan 2022

Try SVT HEVC https://github.com/OpenVisualCloud/SVT-HEVC/releases
I know it takes years of work to make new encoders, would it be worthwhile for developers to use techniques, work, or code from pre-existing encoders (like x264 or x265, ignoring legal issues)? If so, why doesn't videolan (devs of x264 and 5) make an av1 encoder?
