There are far too many video editors for me to tell you which one, but I will share this is the solution for a very simple reason. Video playback is through a directdraw method and would overlay your other animation. As such, you get to create a new video.
I have a Video backdrop that is a movie and want to insert an animation or text in front of the movie while it is playing. When I play the slide the movie will play and the animation and text will disappear. I have both in front of the movie and playing at the same time but they still disappear.
Thanks in advance for any assistance.
