Okay - this is actually not terribly difficult to do directly in Final Cut (only because of the "natural greenscreen"!)
Here's what I did with that clip on youtube:
Here's what my storyline looks like:
Here's my explanation:
In the storyline is the original clip.
Notice there are 3 "blades" - starting with the playhead at the beginning of the clip, I held down the shift key and typed the right arrow 3 times (advanced 30 frames - or in this project 1 sec.)
At the advanced playhead position, I typed Option-F to create a still frame.
I moved the still frame up over the storyline and set the start of the still at the beginning of the storyline clip and the end at the "cut". [edit:] I set the END of the still at the blade line. During playback, it *ends* at this point.
To make this a little quicker, the next step is to apply Keyer to the still frame. For this particular clip, the grass regions are a perfect green screen. Without it, then rotoscoping or combination masks/keys would be necessary.
If you look closely at the top of the compound images, you'll notice trees and such. The next thing you need to do is keyframe the still image to match (track) those items (trees and columns) at the top. REMEMBER you have to set the keyframes to LINEAR (they will be smooth by default).
To the OP, if you don't know how to do this: turn on the Transform tool in the Viewer. Select the clip that is keyframed and you'll see a red "track" with end points. Right click on the end points and change from "Smooth" to "Linear".
Repeat this process for however many copies you need to use.
You will notice that the stills will "bleed" outside the frame. This will be useful while you are keyframing the position "tracks".
When you have finished, apply a Shape Mask on an "Adjustment Layer" over the entire arrangement of clips and stills and mask out the overlaps.
If you run into trouble, let me know — I'll try to sort it out for you.
