Hello Daniel, this won’t help you, but i recently had a similar “unexpected” behavior with applied filters. Mute doesn’t mute - Help/How To - Shotcut Forum
I never had this issue before, and maybe it is becauseof you told me herethat there is a function called “apply copied filters” on the timeline. My Mute-Filter, whicht didn’t mute, was applied by timeline, not pasted by the filter-window, as i normally did before. Because of you mentioned “add a bunch of filters to a clip in timeline”, i stumbled over it.
Maybe it has something to do with each other?
