Created attachment 184322 [details] Journal starting at the moment of clicking "create squence from selection" SUMMARY If I select several video clips, compositions and at least one audio clip from one of my audio tracks, Kdenlive will segfault. If I select the same without audio clips, it works. I tried this several times with different clips and audio clips on different positions within the time line and the result was always the same. STEPS TO REPRODUCE 1. Select some video clips in the time line. 2. Select one audio clip (e.g. some effect sound) from an audio track 3. Choose "Create sequence from selection" from the context menu. OBSERVED RESULT Some log output will generated (see attachment) and finally it segfaults. EXPECTED RESULT New sequence in the project bin. SOFTWARE/OS VERSIONS Operating System: Kubuntu 25.04 KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.3 ADDITIONAL INFORMATION Kdenlive is compiled from source from the latest tag 25.08.0 and everything else works fine. I'm working on very large projects with 100s of clips, 22 tracks, filters, color correction and so on and everything else seems to work fine. Sequences also work btw as long as I do not include audio.
Thanks for your report. I cannot reproduce the issue following your steps. Can you also reproduce with a new project having only 2-3 clips, or is it specific to your project ?
I managed to reproduce it in a new project but I'm not sure yet what exactly causes it. I will try to work out the exact steps.
Ok, here I did a screen recording of a simple example where you can see exactly what I did: https://drive.google.com/drive/folders/1J9_lPSNO0adL0729QKOEejAqB5UyIRRu?usp=drive_link
Thanks a lot for the recording! I was able to reproduce and will work on it!
