I have created a moving object and I want to render it with a movie background.
means I have a avi file and I want to put it in the background and have the scene render over it.
then I can have the object in the video
I hope I explained well.
so would anyone please help me

Thers two options (possibly more)

1. Use a composting program (such as after effects) to add the object to the video file. (This way gives you the best control over intergrating hte object in to the scene)

2. split the video file into a sepperate images and imprt them as an animated image plane anre render everything at once.

The first options by far the best
