how can a canadian do a video in the us?

If you are not a US citizen you cannot legally work in the US without authorization. Getting a driver's license does not fulfill that requirement.

Actually, i beleive they changed the law about this a few years back and, in certain circumstances, visitors to the U.S may be able to work without a permit however, i cant recall exactly what the conditions about this were but, as i say, in some circumstances, you are permitted to work in the US
