dumb question about basic mattes and tracking
How do you make a matte move the same as the camera is moving in the green screen shot? Do people use AE for this? Is there a better program?
Just so I’m being clear, I want to shoot interviews on green screen where the camera is slowing zooming in and otherwise moving or panning a little, and then I want to use a video background, like let’s say a shot of a golf course, where the background shot is tracking the same as the interview shot when I put them together.
What are the ways and programs people use to do this? Do I need a greenscreen which has some sort of dots on it? What program(s) make this easy?
Thanks.

If you havn’t already shot the interviews, the best thing to do would be to not do any zooming with your camera and take care of that in AE. Bring both layers (greenscreen shot and background clip) into AE, and key out the green from the greenscreen shot. Then you should make both layers 3d (hit the cube checkbox next to the layer’s name) and put the greenscreen shot right on top of your background footage. You should then add a new camera (file: new: camera) and do all of your zoomins and stuff there. This will give you much more control and much smoother zoomins than doing it manually with your camera.
As for your question about mattes and tracking, I have an idea, but I’m not exactly sure. You could put a few spots on your greenscreen and motion track them in AE, but the above method would be much better.Hope this helps,

Thanks very much. For some reason I didn’t get the email response when you posted, so I didn’t know anyone had. I haven’t shot the interviews yet, appreciate your advice. Will play with AE to see if I can get that to work.

And I will play around with my green screen setup to see if I can get your original idea to work.
No problem,
