Why not put the zoom sequence on a lower video track and drop your clips on tracks above it?
Also, instead of doing a "sequence" (not sure how you did this), just use one instance of the still image. Place it on Video Track 1, and then Click-drag on the Tail to get its Duration to suit.
Now, Keyframe the fixed Effect>Motion>Scale (and Motion>Position, if necessary), to do the Zoom during that entire Duration.
With your Video Clips on higher Video Tracks, you can Scale them, if necessary to get a PiP (Picture in Picture) look, or just have the appear totally over the animated still.
Hope that this helps,
Worked perfectly! Thanks! I'm in the learning phase now and some of the obvious fixes aren't so obvious...
You might want to also take a look at this FAQ Entry. Steve, besides being our MOD, is a world-class author, and has both his Boot Camp, plus the Learning Series on Muvipix. One can also purchase his highly-recommended books from there too.
While on the Muvipix site, see his articles on Keyframing, as they will come in handy for doing what you describe, and offer so much control.
