(This is in blender cycles.) So I have a tank animation with a green backdrop and on that green backdrop I put a road so it looks like the tank is moving on the road. But the video clip of the tank is stationary so is there a way to move the video clip across the road backdrop to make it look like the tank is moving across the road? Also is there a way to reposition the tank like rotate it to make it aligned with the road backdrop or rescale it? I wish I could send a pic to make it easier but stack exchange crashes when I do.
(This is in the compositing node editor) So my node set up is the army tank with green backdrop in a movie clip node connected to the image of the keying node which is connected to the 2nd image slot of an alpha over node which is connected to composite. The road image is in an image node connected to the 1st image slot of the alpha over.
