Improved masking and keying

The mask isn't perfect, but here's a much better version: (keying too)

I'm still not spending much time on this to perfect the result but it's coming along nicely. Somewhere in the video you can see I nicked the person with the mask. It's really easy to use, but it does take a while.

Keying in Blender -now working!

I finally figured out how to get the keying to work in blender! Here's the screenshot:

It's the same footage as before, just so I have something consistent to work with.
As you can see, I just plugged the mask into the keying node using an invert node and it worked. I had tried plugging the mask into the keying node, but hadn't gotten anything before, so I don't know why it didn't work before, but I have it working now!

I'll see if I can fix the mask in the next post. I'm not going to try to track the background.
