Description ITicDigger 2019-09-26 16:07:04 UTC

SUMMARY
If you lock a track that has a “Composite and transform” transition, save the project, close the application and open the project again, you will get a message like this: Invalid composition transition1 found on track 3 at 589. And the transitions disappear from the track.

STEPS TO REPRODUCE
1. create color clip and add it on track
2. add to this clip “Composite and transform” transition
3. lock track
4 save project
5 close kdenlive
6 open project again


OBSERVED RESULT
 you will get a message like this: Invalid composition transition1 found on track 3 at 589. And the transitions disappear from the track.

EXPECTED RESULT
There should be no error messages and all transitions must be in place

This bug is a show stopper indeed. Spent hours on not.an edit. I do not even recall locking a track or whatnot.

Until there's a fix, is there any workaround, perhaps somewhere in the kdenlive file to edit to cut away the transition whatever cancer blocking kdenlive from loading? Hours if not days are gonna be lost here, if no workaround exist.

It's just sad and unfortunate.

Comment 5 Jean-Baptiste Mardelle 2019-10-29 04:45:13 UTC

Thanks for your report and sorry for this. It is now fixed in git. The transition were indeed correctly saved in the project file, problem was on opening. With the fix, transitions will appear correctly when re-opening the initial project file.

Fix will be in 19.08.3 and I can publish an updated AppImage tomorrow morning as a fix if that helps you.

Comment 6 Jean-Baptiste Mardelle 2019-10-29 08:12:39 UTC

Or easier, you can open the .kdenlive project file in a text editor. Then search for:
kdenlive:locked_track

You should find a line like:
... "kdenlive:locked_track">1</property>

Replace the 1 with a 0 in that line and transitions should load correctly (it will disable the track locking that caused the issue).
