# But . . .
Greenscreen would have meant that he couldn't interact with the background, which (as a video person) is what makes it impressive.

Well done again, sir!*

*You're just too damn good. Stop it now, I say!

# Ah, but you can
if you think of clever ways round it.

# I use green screen too
I also have a blue screen, but I don't know the best settings to use in AE. Can you give me any advice?

# sure,
I actually emailed you a while back about Boxmobiles. The greenscreen work I've seen you do is good though, you seem pretty apt at it!

you can see why this is pretty soul-destroying though, frame by frame!

# The link doesn't work I'm afraid
The problem I have with green screen is preserving the soft motion blurred edge to the footage, the keying seems to remove that

Edit: Got it to work now. Looks like a lot of work went into that.

Anyway, I know what you mean about the keying with moving footage. The best way round it I've come across is procedural matte creation, using a few different mattes pulled from your footage to compose into one final matte, then a bit of spill supression and light wrap and you're done.

# Yup
I used exactly that technique to do this film. Couple of colour ranges and a difference matte, mainly for the edges. And some roto-matting for the hoover pipe. And lots of garbage mattes thrown in for good measure

# I also saw something
about blurring the backgound of what's behind the moving footage, which simultaneously gives lightwrap AND sorts out the problem with the blur. I suppose you'd make it by making an inverse matte of a copied layer of your background footage, heavily blur it and put it over the top of your foreground plate...
