I remember back in 2018 we used do FFmpeg split clips into frames, hit each with GoogLeNet gradient ascent on layers thenn blended prev frame for crude smoothing

SOTA for frame interpretation today is probably RIFE (https://github.com/hzwer/ECCV2022-RIFE) as far as I know, which is fast as hell as well, and really good results still. But it's already 4 years old now, anyone know if there is anything better than RIFE for this sort of stuff today?
