After Effects CS 4 help needed - duplicating man skiing

[jonford]

Hi
Just got Above AE CS4 and am after learning to do 1 particular effect - the effect would be for a skiing video - imagin the skier doing a jump. The original video shows the man skiing off the jump and landing. The FX I want to do is to duplicate the man jumping and have 3 or 4 different images of him at that stage of the jump, and that duplicate of hum would be a still at that particular split second. I know it can be done, I just cant find an example of tutorial
Hope above makes sense
thanks

You have to use motion tracking and masking. This tutorial should help: After Effects - Motion Tracked Snapshots Tutorial. - YouTube
Masking: Adobe After Effects CS5 & CS5.5 * Create a Bezier shape or mask using the Pen tool
Motion Tracking: Adobe After Effects CS5 & CS5.5 * Motion tracking overview and resources

thanks Kevin - will give it a go. Thurston Lang - I think that video used the Echo FX. Very similar. but the video is "duplicated" and played next to it...I think (Im new to this)
thanks again
