I had the same problem with AVIF. My platform allows users to “scrub” through a video file they’ve uploaded by hovering over the thumbnail. To achieve this it creates a grid of 100 representative frames, up to 480px in width per frame. So the images are pretty large and take up a lot of space in JPEG format. File size is important because it reduces lag time before the thumbnail is scrubbable.

We tried AVIF and file sizes were much better but it would take multiple minutes just to generate. We also got feedback from our self-hosted customers that it was using way too many of their system resources.

So we’re now using WebP which generates in about 10 secs using much less CPU. I’m open to JPEG XL if it can improve on those metrics.
