Adding movies to 3d animation

Hi i’d like to get a few movies to play while the camera rotates around a 3d object (cross). I just want to know how to make sure the movie plays while the camera moves on the timeline? Please see pic.

NEVERMIND!!! I figured it out… just drag and drop… And press play on timeline. Voila! …

OK I added a video to a layout and it plays when the timeline moves… but for some reason it’s not rendering in the animation. Whats going on here?
All I see is the 3d cross I don’t see the movie planes around it.

By drag and dropping you only added a reference image - it will not render. If you do not have “Images as Planes” add-on enabled. Try adding that and adding the movie/image through it.
