I’m pretty sure there is an element in WebTools-NG that will tell you the ones that are already processed if you have anything that can open csv files.
Also if you go to the media info for any episode or movie
in that middle section called “part” there will be a further entry (called indexes I think) and the result will say “sd”
that means theyr’e generated.
Plus of course if there is anything you particularly want to generate them for immediately you can click analyse.
