SUMMARY Group effect or effects applied to group, does not work properly on Flatpak version. STEPS TO REPRODUCE 1. Add audio clip to timline. 2. Cut clip into three pieces / clips of similar length. 3. Select three pieces / clips. 4. Add volume effect to all three clips. 5. Enable Group Effect. 6. Click on one clips to activate it. 7. Add keyframe to volume effect. OBSERVED RESULT Keyframe is only added to active clip and not to other two parts. Occasionally, keyframe might be added to two clips, keyframe is sometimes set to "discreet" interpolation mode. EXPECTED RESULT Keyframe to be added to all 3 three clips. SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Plasma Version: KDE Frameworks Version: 6.11.0 Qt Version: 6.8.2 ADDITIONAL INFORMATION This issue was observed in Kdenlive 24.12.1 flatpak as well. It was tested using Transform effect as well. The steps above rely on prior experience or knowledge of Group Effect feature.

> > It was tested using Transform effect as well. > Is this still the case for 25.12.1 ? Using Kdenlive 25.12.1 The issue persist when working with audio + volume effect. Working with images + Transform effects, the group effect works properly and adds keyframes for all images, with the same conditions as above, 3 images, same length. I tested it with video as well and it works. Conclusion, group effect keyframes work with images and videos (+ Transform effect), but not with audio (+ volume effect).
