About AV1 and AVIF codec on Linux
AV1: video codec with MIME type video/mp4; codecs="av1" or video/mp4; codecs="av01.0.05M.08"
AVIF: still image with MIME type image/avif
Suggested Use Cases
If hardware encoding/decoding is available, the AV1 codec is a good way to store videos with smaller size, compared to H.264, and even smaller than H.265.
The noise suppression is great, but this also means loss of fine details and overall fidelity here.
AVIF images and AV1 videos are supported by the following Linux applications (and more):
AVIF
Gimp since 2.10.22, ImageMagick, vlc, ffmpeg, mpv, exiftool, Firefox, Chrome, and others.
