How to reproduce : 1- Create a new project and save it. 2- Import a PNG image sequence that is from the same location as the project file so that the path is set to relative in the project file. 3- So far so good, the image sequence clip is displayed correctly. 4- Save and Close the project. 5- Reopen the project. 6- Now the image sequence clip is displayed as "invalid".

Fix slideshow clips displayed as invalid when re-opening project M +17 -0 src/doc/documentvalidator.cpp M +7 -2 src/project/dialogs/slideshowclip.cpp https://commits.kde.org/kdenlive/0ce898669ab4efe6d2a6bf6ac2a1edf57c5e3c1f
This bug was triggered when using the "Filename pattern" method for slideshow (or the "import image sequence" checkbox from add clip). It will work correctly now with this patch. As a workaround for people using Kdenlive <= 16.12.1, you can open your .kdenlive project file in text editor and replace occurences of "?begin:" with "?begin=" (having = instead of : fixes the error).
