SUMMARY I haven't tried to reproduce this yet, but it's something I'll start looking out for. I've noticed the slowed-down clips in my timeline are mysteriously missing a few times now. I'm not using Time Remap, just "Change Speed". I usually put the clip in an empty space, Change Speed, type "1" and let it autocorrect me to the slowest speed that fits within its gap. STEPS TO REPRODUCE 1. Have clips with slow speed 2. save project 3. load project? OBSERVED RESULT Empty gaps in my timeline EXPECTED RESULT Slowed-down clip to plug the gap SOFTWARE/OS VERSIONS Operating System: Kubuntu 25.10 KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.17.0 Qt Version: 6.9.2 Kernel Version: 6.17.0-6-generic (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 2600 Six-Core Processor Memory: 16 GiB of RAM (15.0 GiB usable) Graphics Processor: NVIDIA GeForce RTX 2080
I'm almost done with my current project and then I can close Kdenlive and start a small test project. But my current theory is this might be a rounding issue? If I'm setting the clip to a speed of 11.642346% so it fills the gap perfectly and save the project. Maybe something goes wrong in the serialization/deserialization of the file? Maybe when I load the file it comes back as 11.642345% (slightly slower) and thus it no longer fits in its gap? Just a theory.
I've been trying to reproduce this issue, but I managed to reproduce a different issue instead that's maybe related: https://bugs.kde.org/show_bug.cgi?id=511851
