How can you synchronize a background image (sprite) and a backdrop ?
What I have is a movie that switches between 3D sprites and Quicktime movies. In the 3D sprite I have added a backdrop. Further, because I don't want to have a black screen between a switch, I also set the background image as a sprite. So if the 3D animation is done, I set that sprite to invisible. The movie shows the background image. But it is not exactly the same and it looks like the background seems to move a little.
I know that director scales ...
