I think this is definitely the most common response. AVIF, as a video intra-frame based codec, works best at very low bitrates. JPEG XL is considerably better at high bitrates.
- WithinReason 3y agoI'm guessing the reason is that for predicting video frames hallucinating detail is undesirable, so you would rather remove detail than add non-existent detail. AVIF also seems to have some kind of deblocking filter which JXL lacks, to my surprise.
- worldofmatthew 3y agoYou can also adjust that deblocking in AVIF.
- JyrkiAlakuijala 3y agoAVIF deblocking filter is one axis at a time whereas JPEG XL is doing an axis-non-separable filter, 2d selection at once. It is not clear that AVIF can be parameterised to do similar filtering to JPEG XL -- at least it hasn't been done yet.
