Or do you know of any videos online that did? I plan on shooting one in the near future and am unsure of the lighting situation and how to do it effectively.

Same as with any other camera. Light the background evenly and close to 100 IRE (or 2-3 stops hotter than the foreground, light the foreground independently however you want.

What type of lights would you use to evenly light the backdrop?

Also, would this be the same method as a photographer shooting on a white backdrop? Examples of how to set those shots up are plentiful on youtube/vimeo but harder to find for shooting video.

There's a really good link to a tutorial on shooting and lighting limbo white bg's posted somewhere here. I was looking for it the other day and couldn't find it. Maybe someone knows. I think it was originally on Vimeo.

Coming from a still photography background, I use white backgrounds for stills all the time. I have a room similar in dimension to the above video demonstration, so I keep my background one to one and a half stops brighter than my subject is light. If I go brighter to two stops I get too much bounced lighting back from the background onto the subject.

I also use free standing closet pocket doors to hide the lights onto the background to flag them from the subject and camera.

In the past I tried this with a Canon HV30 and never got it to work, now with the 7D it works great with the manual controls. I use 5500k cfl's as I also have large windows and these lights can match daylight.

The dynamic range of the 7D is very limited. Any surface two and a half stop over neutral grey wil burn out. Here is an example of how easy it can be done.

So if my subject is at 8, my light should be two stops above...so 16 (or 2 and a half)

If you use a spot meter (the lightmeter in your cam will do i believe) and measure the white background, your exposure should be two stops or more higher than the white background. If youre background reflects f16, your exposure should be 8 or 5.6 and a half.

If you do not have a seperat lightmeter (spot meter) make sure your camera is not set for "evaluating measurment".
