I am new at video editing and need to create a virtual video of an interview with a manager of a factory for my sons homework and I came across Green Screens. I think that what I could do is use the green screen with the "manager" on one side and the "interviewer" on the other and put an image behind them of perhaps the factory or something like that. I know what green screens are now and how to set them up but I still have several questions:
a) How should I film using a green screen
b) How do I edit the film so that there is an image behind the people.
The school has a green screen so that is not a problem but keep in mine that all software that I use should be free. I do have iMovie HD and iMovie '09 though.
