You do get nervous maybe also because inter-frame/motion prediction residuals absolutely don't look like a natural still image.
Still image research is not done for motion prediction residuals, for example my wavelet codec (NHW) puts forward neatness of (natural) images, but I don't know if it'll work as-is with inter-frame residuals which have completely different properties.-It would be challenging (for me) to know if wavelet image codecs could be effectively tuned to work well with a motion prediction scheme and its residuals-... Btw, I'm also waiting eagerly to evaluate this new version of AV1 in AVIF.
