    How to make an effect stop and start again?


      How do I make an effect start stop and than start again?


      I'm trying to blur faces (I finally figured out how to do that---copy the video to a 2nd layer and use the mosiac and crop effects) but how do I make the effect only appear when the face is in the screen as multiple times throughout the video clip the subjects face goes off camera.  In the effect controls window it doesn't give me an option to add a blank keyframe.


      Any advice on how to have this effect start/stop multiple times in one clip??
