If I export a video (specifically - I’ve copied timeline to source and exported a subset of the video), add the resulting video to the playlist, then try to drag it to the timeline, I get the message “You cannot add a project to itself”. But I’m not trying to add a project, I’m trying to add a video. In fact, if I save Shotcut, with the exported video still in the playlist, re-open Shotcut, then I can drag the video into the timeline.
So why do I get the message “You cannot add a project to itself” when in fact, I can add the offending video to the timeline (but in a roundabout way)?
I’ve tried this on version 20.10.31 and 20.11.28 (on Windows 10, 64bit, but I’d be surprised if my operating system matters).
