[SUGGESTION] Cross-platform command-line AV1 / VP9 / HEVC / H264 / VVC encoding framework with per scene quality encoding

[MarcoRavich]

I just found this interesting framework that aims to:

Spliting video by scenes for parallel encoding because AV1 encoders are currently not good at multithreading, encoding is limited to single or couple of threads at the same time.

• PySceneDetect used for spliting video by scenes and running multiple encoders.
• Fastest way to encode AV1 without losing quality, as fast as many CPU cores you have :).
• Target Quality mode. Targeting end result reference visual quality. VMAF used as substructure
• Resuming encoding without loss of encoded progress.
• Simple and clean console look.
• Automatic detection of the number of workers the host can handle.
• Building encoding queue with bigger files first, minimizing waiting for the last scene to encode.
• Both video and audio transcoding with FFmpeg.
• Logging of progress of all encoders.

Hope that helps/inspires !

It's a really cool library with smart ideas. I really like the idea of per-scene quality detection, kinda like advanced CRF. That would be a cool thing to try to figure out long term.

Sadly can't directly incorporate their code as it is GPL licensed, so would have to use it as a library like I do FFmpeg. Then it also uses each raw encoder, so would turn into a cascading support issue to include all those / have support sections for each. So I don't think I will be looking to include it as another tool anytime soon, but it's a great tool that people should know about!

Oh, that's me :eyes:

Dunno if can help, but here's a GUI for it: https://github.com/natis1/qencoder

Fun tool, more stars than FastFlix, use it for speeding up your software AV1 folks!
