Anyone know 3Ds Max?

[Ravioli]

Ive been working with this program for years and i just now remember an old tutorial were you can film a real life video, import it, and add your CGI animations to it. Im using 3Ds Max 9 and i cant find the tutorial nor the name of the technique used so i cant find any tutorials online. The tutorial involved animating a CGI rhino ontop of a real life polo table filmed with a real camera.

Does anyone remember the tutorial, or the name of the technique, or anything at all about this?

thanks but im using moving cameras, so the video is constantly moving. I found out more about it tho, its called Camera Tracking. Ive tried it, its a pain in the ass and only works like 1% of the time. If anyone could find any more tutorials on camera tracking that would be awesome.

Thanks for the help tho
