FCP 7 "slide wipe" transition problem

Please, please help me!
I am doing a music video with my two Dawn-syndrom kids from my School, and everything was OK, till the end scene. I try to do the same wipe transitions between the clips into the clip (picture frame on the wall), like I do wiping on my iPhone between screens.

I don’t know how to describe better my problem, so I found music video with the same Transitions effect, like I want to do.
Here is the link:
(Josh Turner - Find me a Baby)

You can see on 1:56 – 2:01, how he "slide wipe” the clips into the frame, like on iPad, or iPhone…
How can I do the same. My “ empty Picture Frame" will be on the wall, the actor will stand in front and do the same with her hand like Josh Turner did in his video. Inside Frame will change 3-4 pictures.

I try all transitions, but unfortunately…. Than I try with Keyframe motion, but….
I bought a Book from Michael Wohl - FCP 7 Advanced Editing, but couldn't found how to do it.
Should I re-record the final scene?


Please, please help!

Best regards from Slovenia!

Would all have to be done inside Motion. A plugin isn't going to do that for you in FCP7.

Thanks!

I solve the problem with BIG help from Larry Jordan - FCP expert. I did it with Green screen and Chroma Keyer!
