not sure if this is in the right place but here goes...
i have a pulsating orb, and i want to have an image rotating around it, that part im ok with
the effect i want the image to have is
-complete a full cycle in 10secs (i can do)
-as the image begins to reach the front of the orb i want to gradually slow
the image so you can see it and let it continue rotating at a faster pace until it comes round again (im struggling to complete)
no magic involved. Just add more keyframes and adjust the timing. As an alternative you can also tie in other effects like Transform or Motion Tile before the cylinder to get an extra layer of control.
Keyframe interpolation is the key to slowing things down. I'd suggest that you type "animating keyframes" in the Search Help field at the top right corner of AE and study up on the techniques used to control animation. The first link is a good place to start.
