Converting big video library with av1
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.
- No library usage documentation for SVT-AV1?
- AOM or SVT-AV1 on 5950X? video is 8K 60fps 60Mbit/s

SVT-AV1 HDR Encoding (libsvtav1 with ffmpeg)
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
- Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder)
- AV1 Video Codec
- 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.).

- 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?

YouTube is now building its own video-transcoding chips
By now Intel has released an open source encoder (BSD-2 + patent grants), tuned for their Xeons:

How to set the speed mode in SVT-VP9 encoder ?
If you are using the SVT-VP9 binary it's -enc-mode https://github.com/OpenVisualCloud/SVT-VP9/blob/master/Docs/svt-vp9_encoder_user_guide.md Somehow it's per default on the fastest, but worst setting.
What are some alternatives?
obs-amd-encoder - AMD Advanced Media Framework Encoder Plugin for Open Broadcaster Studio
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.
