What is your operating system?
Windows 10 x64
What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
22.10.25, also on beta and some older versions, this is not really new
Can you repeat the problem? If so, what are the steps?
After reaching a point in the project where there’s quite a bit of cuts, the undo function starts to take unbearably long to the point that it’s basically faster to close and reopen the file (I save very often).
I am aware that my project is arguably a bit more complex than average but my thinking is this: if I cut a clip (Ctrl+X) and then paste it in place (Ctrl+V), it should basically take the same processing as Ripple delete (X) then Undo (Ctrl+Z) barring some hidden housekeeping (in my case the nearby marker got deleted, undo would have fixed this) - but the first action is basically sub second yet undo takes about 33s so something doesn’t look right here.
If I undo something at the begining of the timeline it takes longer than something at the end.
If I undo a Lift (so no need to ripple all the timeline) it is very fast.
This is my 36 min timeline with 493 clips over 4 video tracks (actually 2 video and 2 photo only) and 1 audio
This is the duration with undo:
And cut + paste:
I’ve searched the forum and it doesn’t seem to be a lot of discussion around this, maybe it is just me but it’s been happening to all my project files proportionally to their length/complexity.
Edit: just realised a way better report would have been the reverse: undo-ing an insert with ripple enabled, basically the “ripple delete” action of a clip when done by undo takes 30s in this situation.
