I've recently upgraded from Movie Edit Pro Plus 2015 to Movie Edit Pro Premium 2022. I never had this issue on the old version but only had it on the new version, making me think that I may just be missing something.
But when I'm editing a still image in a film, and I'm trying to use key frames to make it move from one position to the next (which I was able to do easily with the old version) the button to add a new key frame is always greyed out. Furthermore, with the other video options, such as rotation and camera zoom, it ISN'T greyed out, and I can key frame as normal. So I'm confused as to why I can't do this for 'Size/Position/Rotation.
I have tried updating my software and restarting the program but the problem continues to persist. I may just be misunderstanding something as it is a new software, but I don't see what I'm doing wrong.
