In the next update, the "Speed boost" and "Scene Shift Detection" features in Frame Analysis will be optimized for faster processing. The code for these two features has been refactored, and I'm running tests to ensure there are no bugs.
And regarding the "auto downscale" feature in the last beta: to clarify, this only auto-downscales super high-res images that would crash the engine. It resizes them to the max supported size to preserve detail, so your images won't be downscaled for no reason. (Plus, it's quite unlikely to trigger this feature for most people, since these kinds of images usually don't require super-res.)
I'm really sorry I didn't write a post to explain this beforehand, recently I just moved to another city for reliable water and electricity supply.
Thank you for supporting this project!❤️ I'm also working on more updates for super-res models, so stay tuned!
