Greenscreen Induction

Firstly I applied a checkerboard effect onto a new solid, so I could distinguish what areas dissapear more effectively.

Then after bringing the solid behind and making it fully opaque, I selected the Keylight effect tool;

Then after using the eyedropper tool and selecting the greenscreen, the background dissapeared, however certain bits were left behind and some of his dress that had tint green fragments in had become transparent. So by changing the setting to "screen matt" and by then adjusting the white and black balance to make sure that the whole of the background was black and whole of my character by white, this then ensured that my character would not be slightly transparent. However I was warned that I should not go over the 50% value as beyond then your footage that you dont want to disappear will start being eaten up by the background and nosie will appear in the footage.

Then we made a mask so that all the bits of the background that had white bits in, was fully deleted. The mask was made with the pen tool.

I then was able to experiment myself.

Because of the hippie personality of my character I chose a psychedelic GIF as my background and applied it behind. I then added a few clouds to enhance that "godlike" "messiah" feel he has with his robes and hair, which I keyframed to fade in and out with his legs like the movement is shifting the clouds;

Ta da!

My results are both bizarre and amusing. His personality how SHINES out of him and I love it.
