SUMMARY This may be similar to bug #447786 An image on V2 is rotoscoped and a transform effect is added (in order to move the image around). This changes the rotoscope area (apparently it squishes it horizontally). STEPS TO REPRODUCE 1. Put a color clip on V1, an image on V2 2. Add rotoscope effect to image on V2 and rotoscope an area 3. Add a transform effect to image on V2 OBSERVED RESULT Rotoscope area is deformed/squished horizontally and hence a different area of the image is visible. EXPECTED RESULT No change to the rotoscoped area SOFTWARE/OS VERSIONS Linux: Pop!_OS 22.04 LTS 64-bit GNOME: 42.5 Windowing System: X11 (available in About System) KDENLIVE: 22.08.3 (but replicated in 22.04.3 and 21.04.3) KDE Frameworks Version: 5.98.0 Qt Version: 5.15.5 MLT: 7.10.0 ADDITIONAL INFORMATION

This only happens if the rotoscoped image has a different resolution than the project. If the project has the same resolution than the image a transform effect does not change the rotoscoped area.

Thanks for your report. I started working on this issue and have an almost working patch. I hope to push the fix to MLT by the end of the week.

Ok, so I just pushed the fix in MLT. It will be included in today's daily development AppImage build. Would be great if you can test - it should be ready in 5 hours from now (ensure you download build number #427 or more) : https://binary-factory.kde.org/view/AppImage/job/Kdenlive_Nightly_appimage-centos7/
