There are a number of ways to accomplish this. Animate the Motion effect for the pan, then use a Fade transition to dip between the clips.
Want a fade, but a different transition? Animate the pan plus a Transparency effect Fade Out. Then add the transition.
In this example, Motion effect moves the image left to right, Transparency effect fades it, then Bounce transition has been added between clips.

Available effects vary slightly between VP versions. Use the latest. For licensed users upgrades are free for up to six months from purchase date. After that, VP will continue to fully function but a fee will be required in order to register the newest. Retain your old install file and registration info.
