I'd like to create a simple effect whereby an image of a boot print becomes footprints walking across the screen. I've got a png of a boot print. I can add a motion path. But is there a behaviour that will write on - write of the image so it appears to be walking? Tried replicator but cant get it to work. Any help really, really appreciated.

    A Replicator is the way to go to start.  Draw a bezier line in the path you want the footsteps to go, then uncheck its visibility checkbox so you can't see it.  Create a Replicator of your footprint.  Change Shape to Geometry, drag-and-drop the bezier line into the Shape Source box.  Set the number of points for the number of total footprints you want to end up with.  Check off Align Angle and change Angle to 90 degrees.

     

    Now, I'd take and draw a shape and animate (keyframe) that shape to act as a mask and reveal the footprints one by one as needed.

     

    That's the quick and dirty way to do it.  But this does inspire me for a new macProVideo.com tutorial on how to do this in Motion.  There are some more advanced options that could make it cleaner.

    "So the footprints need to follow a motion path."

     

    I told you how that is done by using Geometry for the Shape parameter.

     

    You'll have to do tests on that building live to figure out the correct placement of your foot steps.
