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?

If you want to save what you have, you'll have to render your masked video and THEN slow it down. That's the easiest way.

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.

Go to AE's Online Help. Look up the topic of prerendering. The search function works very well.

... 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.
