How do I make a Swivel Green Screen Camera Setup? Answered

I am a filmmaker and one of the things I adore is special effects.  One of things I want to do is make a simple effect in which I use a real physical model of a vehicle and I put it in front of a green screen.  However give it the illusion that a camera is panning around the whole thing while it's driving through whatever background I put in place of the green screen.  The way I want to do this is to make a swivel which on one end has a small green screen rigged on one end of the swivel and on the other end of it, a camera that is lined up with it. So that when I turn the swivel the camera would always follow the green screen. So that when I edit it in effects it would look as if whatever is in front of the green screen is traveling along an endless background while the camera is panning around the object.

Hundred different ways you can make something like that depending on how big you need the rig to be.

Canvas and camera are not the key factors here. It's the size of the object being film that dictates the rig. You can do something as simple as cutting the middle out of a lazy susan to allow the prop to be placed and mount your canvas and camera to the outer edge. Or you can got to the hobby store and pick up some train track and a couple of cars. Mount your equipment to the cars and place them on opposite side of the track. Connect the cars with whatever you can that will wrap around either side of the cars so they move as one. If you need a larger rig a couple of skate boards can be modified so they run in a large circle and can also be connected to each other with a curved cut from ply wood so they move as one. All depends on the size you need the rig to be to go around the prop you want to film. Pretty much anything that roles can be used. Preferably something on some sort of track so the movement is steady and consistent.

The lazy Susan is a good idea especially if it's a square shaped one. Now the way I want this particular rig to set up, is to have it so the source of the swivel is over the prop instead of under. Basically I'd be hanging the swivel. How would that be possible. Also what would be a good means to turn the thing once it's completed?

Your not vary mechanically minded are you. Think through it. The susan will need to be mounted to something like a board. That board would be flipped upside down and set on some legs. Make sure the board it large enough to keep the leg out of the way of the gear mounted to the susan. Alternately the susan can be mounted to the under side of a table. The system can be turned by hand or with a decent sized motor and belt drive. The motor will mount near the susan so a belt can go around the edge of the suzan and motor's drive shaft. Multiple motor options are out there but one with a gear box will be best. Then a simple battery setup and switch will take care of things. You can go more complex and use a micro controller to run things. In this case a round wood susan would be best. Then you can use some clamps and screws to mount the camera mount and canvas. Course the camera will be upside down as well but that can be fixed in editing.
