@MusicalBox, have you tried the Glaxnimate program that was added in Shotcut in the recent beta release here?
It would be better to do these kinds of animation presets in Glaxnimate for use in Shotcut because the animations are scalable to any resolution. That means the image quality won’t degrade no matter how high you go in resolution. So you can just do them one time and not have to prepare new animations for other resolutions.
