Last week, I encoded a bunch of images into AVIF. For the same dimensions and roughly same file size, AVIF images are dramatically clearer than JPEG. I wish I could start using them right now, but: 1. The AVIF encoder I was using[0] is based off libaom, which means a 1080p image takes almost 30 seconds to encode. rav1e is supposedly much faster, so I wonder how well it would do for AVIF. 2. Almost no viewer or browser support, and what does is usually some kind of beta or preview.

> Almost no viewer or browser support For browser support it should be possible to implement a poly-fill similar to https://github.com/UprootLabs/poly-flif https://github.com/UprootLabs/poly-flif which renders images in the FLIF format (https://flif.info/ https://flif.info/) into canvas elements. FLIF as a format might be worth looking at while you are reviewing the area.

  There is an AVIF polyfill, but it has lots of important edge cases. https://github.com/Kagami/avif.js https://github.com/Kagami/avif.js I'd rather keep it simple and not deal with more JS, and I'm OK with using JPEG for now. (I've been using mozJPEG for years)

> which means a 1080p image takes almost 30 seconds to encode. As you mention, rav1e would help, but HEVC/HEIF is only acceptable in speed due to hardware support. AV1 is slowly making its way into silicon, though. I'm personally interested in seeing this make its way into cameras - even when I shoot in RAW, I often just use the off-camera JPG. I'd love for that to be AVIF instead.
