Hi Anjaneai,
Thanks for the ideas. The dark gray border at the top and bottom are ok, the problem is the light gray border I get. I tried the Skin Editor, but it only removed the top and bottom dark gray borders, not the gray.
I can't use the Flash on the slide because I need them to be HTML 5 compliant.
Here's a link to my blastoff animation files that were exported from Flash using the Toolkit for CreateJS.
