A transition using an image (slide an image across the screen)

Question

Hi everyone,
Hopefully a good question I am about to ask.  I have 2 clips, and wish to use an image as the transition between those 2 clips.  I've seen this sometimes
on TV, where you'll see a clip playing, then a graphic is used - like a side swipe for example, coming in from the left, a graphic slides in from the left, passes
through the middle of the screen, and exits on the right, as it exits, the 2nd clip is now playing.
Does anyone know how to accomplish this ?  I thought perhaps there would be a canned video transition available, but none of them allow me to
add an image to any of those effects ( for example in "slide" category under "Slide" in the video transition effect panel.
Thanks for your time !
Dave.

When you unpin it, you can go past the beginning and the end of the clip in the Effect Controls Panel.
As for getting them to run at the same speed, consider this...
You have to wait to start the wipe until the graphic is in the frame and you have to end the wipe before the graphic leaves the frame.
So, figure out the exact middle, and work both forwards and backwards from there. To find the middle of the wipe should be easy, it is generally right at the cut. And finding the middle of the graphic should be easy because it usuaaly starts there.  So force a keyframe at that point by clicking on the diamond.
As I write this I realize you need to know where the center of the graphic is so that you can start the wipe when exactly half of the graphic is on screen and end it when exactly half is off screen. So start with the middle, then go to the beginning of the wipe and make sure that the graphic is half on and half off on the left. Then go to the end of the wipe and make sure the graphic is at that halfway point on the right.
The math shoulf force this to work.
