Currently when stopping a video/gif from upscaling the temp folder where the frames are located is not deleted, i guess this is to implement the resume feature. I'd suggest to expose a option that ignores this behaviour and does cleanup regardless
Set the noResume property to true and it will always delete the frame folder, thus making it impossible for it to resume, but that's what you asked for.
