Actually, there is one Motion feature that I would like: the ability to stretch an image vertically. I have two current projects consisting of stills recording a scene which changes every few days or weeks. The stills are displayed in sequence with a dissolve or wipe transition. (An example is a country scene showing seasonal changes.)
Although each still is taken with the same camera in the same position and always at the full wideangle setting, I need to adjust the Scale and Rotation slightly in Viewer > Motion tab.
I also need to change the scale either vertically or horizontally (why I don't know) to get accurate superposition of the various objects in the scene. The only way that I can find to do that vertically is to reduce the Aspect Ratio and then increase the Scale, each to the degree necessary. A Vertical Scale feature would be easier and more accurate. (Of course, I can do that in Photoshop, but Photoshop is not suited to accurate superimposition of the type that I need.)
I will put it to Apple as a Wish.
