Maybe dumb question: If JPEG XL beats avif, and both are royalty free, shouldn't the AV group create a new video format based on av1 that for I-frames uses JPEG

Maybe dumb question: If JPEG XL beats avif, and both are royalty free, shouldn't the AV group create a new video format based on av1 that for I-frames uses JPEG XL?
I mean, it feels like the same static image codec should be used in whatever free standard is being pushed for both video I-frames and images, since the problem is basically the same.
- rhn_mk1 3y agoIIRC, JPEG XL beats avif on high-quality images, and avif is better on low quality. For typical vieo encoding, you don't care about perfection that much.
- formerly_proven 3y agoSpecifically, the biggest users of video codecs are video streaming websites/services where bitrate, not quality, is king. Logically, their codecs of choice are optimized toward the low bitrate, "sorta acceptable, but I thought I bought a 4K TV?" quality corner.
- The_Colonel 3y agoYeah, while in the case of images, the quality requirements are usually way higher.
