Reverse direction of Ken Burns effect?

I took some footage from our car and made some still shots of some of it. I would like to have the Ken Burns effect all zooming or panning the same way, however.

Currently, one shot zooms in and the next zooms out, so it looks as if the "action" is moving in and out in the slideshow, which is a bit confusing and not the desired effect of moving away.

Is there some way of making the Ken Burns effect go all the same way? I know how to remove it and would like to keep it in if possible.

Thanks.
