Cloning would require use of the "green screen" effect.
Not really. It's quite possible to do this with a simple locked off camera and two passes, using the time honoured split screen effect. However, as the
standard version of Studio doesn't allow for a second proper video track, I'm not sure if it is possible even then.
A workround with the title track might work, using JPs effects to do a crop, but I wouldn't like to promise anything
