Using a green screen, we filmed me talking to empty space outside and in front of the green screen then I combined the two to create the effect that I was talking to myself.
Using footage of William on a green screen I made a smaller and larger version of him, one dancing in the sky and the other looking up at him from the ground. I did this by using the 'crop', 'ultra key', and 'motion' tool.
Firstly, I placed the video of William over the video of the stage and locked the 'video 1' section. To create the effect of William being a giant on stage I used the crop tool and adjusted the percentage of left, top, right and bottom.
