    Posted by Deepak Adhikary on May 31, 2010 at 11:14 am

    Hey, I have a problem that I hope someone can help me with. I rotoscoped a mask around a person in a video that I’m making. I remapped the time of the footage to make it slower, however its now too jerky and I want to put it back without messing up all the keyframes of the mask. Is there a way to extend the keyframes, but keep them relative to each other so that I don’t have to rotoscope all over a gain?

    The problem is though that I also have a lot of particle layers on top of the video as well that I want to keep the same speed.

    … or you could precomp the offending layers, then time-stretch the precomp in the main comp by using the stretch column (like Modes or Parent) in the timeline.

    Yes; select all the keyframes, from first to last. Hold Option/Alt while dragging the last keyframe, and all keyframes in between will adjust proportionately. See Move keyframes in time from the help system for more.
