Putting it into After Effects

so I have put all the green screen shots we are using into After Effects and have keyed out the green screen. This was a much longer process than I thought. The main reason for this was because the green was not evenly lit. I had to keep adding layer masks to key out the green.

The other problem was the white tracking markers. I had to add tiny layer masks on top of each one and then make sure it kept covered through out the whole clip. This took a long time because there were about eight on each clip and there are about six or seven clips. On one clip there are sixteen markers and they move because the camera moves so I had to make sure they kept covered by animating the masks. Here is a screen shot of an example of all the masks.

There was a shot that we were going to use of me walking away from the screen. I was wearing black converse shoes and this was the scene:

When I tried to key out the green, half the shoes were keyed out as well. Apart from layer masking it frame by frame there was no way to get around it. I tried using colour range rather than keylight but that didn't work as the grey and white from the shoes started disappearing. In the end I just had to scrap the shot. It was the only one that wouldn't work and we were advised when we shot it that it may not work anyway.

It has taken me about three days to fully key out the green and tracking markers. It took a lot of focus and the masking was the most aggravating thing I have had to do.

The next task is to track the footage where the camera is moving.
