But suppose I have a moef that's 10 seconds long and I apply it on a 1-second clip. Motion will fudge all the timing numbers so keyframes and relative position in the clip basically work out right, but if I try to calculate absolute times, it will appear to my effect as though 10 seconds have elapsed, instead of 1. > > If the effect relies on clock time, everything is going to move 10x faster than it should. There are lots of effects that work this way -- flicker, camera shake, simulated clouds, etc. This could be a show-stopper problem for a lot of people. At this time, I don't think there's a way to do what you want. It will be time-stretched. Please file a bug.
