How do I replace the background?
I did the "Rotoscope" on my talent, removing the background. Looks great, successful. I imported a jpeg photo of a beach, for the new background....It's looks great...my actor is now on a beach.
I press "spacebar", running the scene...and the beach jpeg runs for a frame, then disappears. The original background and clip comes back....Why does the beach jpeg disappear? What am I doing wrong?
