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.).

Containerizing AOM AV1 and encoding videos with FFmpeg in an Node.js app
I have recently had the opportunity to work and study the AV1 Codec by AOM (Alliance for Open Media). It is the state-of-the-art video codec for manipulating videos today, and it is stunning how it is able to compress videos producing files with reduced size and a pretty much untouched quality (I will later do a small comparison with the ancestor AVC/H.264 by MPEG). And since I am a big, better huge fan of FFmpeg I cannot step back from compiling a fully working FFmpeg binary within a container image. Later I will describe how I achieved that and how it can be used within a Node.js application.

Qualcomm announces AV1 chipset while at the same time rejecting AOM license
How so? The AV1 specification is available as an official download on the public internet. The specification points to https://aomedia.org/license/ for licensing information. There's no need to sign anything in order to make use of AV1, as permission is granted to make use of AV1 with conditions.
