Created attachment 157407 [details] Timeline screenshot: original grouped clip (left), duplicated grouped clip with speed changed to 25 % (right) SUMMARY Changing the speed of a clip only works on the video and audio, not the title(s), causing titles to stay at their original place. STEPS TO REPRODUCE 1. add a video + audio clip in the timeline 2. add title(s) clip(s) on a video track above 3. group everything 4. select everything 5. right click on one of the pieces and select "change speed" 6. set speed to 25% OBSERVED RESULT Only the right-clicked clip has its speed changed, all of the rest stays in place, which means the titles are not at the right place anymore. EXPECTED RESULT Titles follow the speed change, staying at their correct relative position. SOFTWARE/OS VERSIONS FreeBSD 13.1 KDE 5.101.1 Qt Version 5.15.7 Kdenlive 22.12.2 ADDITIONAL INFORMATION
