This is pretty cool. There’s a dearth of higher bit depth formats that are also compressed.

EXR and TIFF are really the only ones most people use but this opens up a fairly interesting option now for use cases where size is important.

Does this extend to the video codec? This would be pretty amazing for media reviews if so.

So when will support come to libavif, libaom, aom-tools and concerned packages? Are they pushed on to Arch already? Or still just upstream github for now?

The layering reminds me a bit of opus 1.6 which similarly maintains backwards compatibility while laying in better audio for newer decoders, (and as a scalable decoding for those who don't want to use as much decode compute). https://opus-codec.org/demo/opus-1.6/ https://news.ycombinator.com/item?id=46284313
