Green Screen

I decided to try to do some green screen my avatar in SL before a green screen and superimpose her on some real life footage. I filmed the beach when we were in Florida...waves rolling, seagulls squawking. It's nothing exciting but thought it was plain enough i could easily put my avie in there without worrying about walking over people in the RL footage.

I built a green screen studio in SecondLife. It's a big cylinder and floor *didn't put a roof but may need to because sometimes the camera moves up sometimes as you walk and the shot of blue sky messes up. Here are a couple of shots of the studio with my avatar in it. I"m the little tiny dot since my camera is pulled way up. I used a megaprim to make the studio and colored the cylinder and the floor prim *another megaprim* just basic green.

Here's a closeup of me in the studio. You can see the seam where the cylinder meets the floor.

I played around with the windlight settings and found that one called Nam Optimal Skin1 completely wiped out that line. I took a couple of pictures with that setting. No Seam! I gotta tell ya tho - makes walking hard because there's no clue where the walls are. And sometimes you'll run into the wall and your camera will go outside. Not sure how to deal with that yet.

Here's a bit of the footage i shot in the green screen. It's not very exciting. Remember I mentioned the fact that there are no clues to where the walls are? Well that means it kind of looks like my avatar is walking in place.

Why isn't there a clip of the final product? iMovie seems to make it very very easy to do green screen..there's an option in the menu for goodness sakes. I'm doing something wrong...and yes, I can boil water and I can walk and chew gum. But. at this point i keep getting xray looking results for my avatar.  The two clips individually look just fine. I drop the avatar footage on the real life footage, pick green screen..and wham...xray. Not what I wanted at all. So hopefully I'll figure it out and add a paragraph and a clip..very soon..*fingers crossed*

Here's a clip with problems..that xray issue I mentioned and fuzzy footage. Not sure what happened.

ANd here's a clip that worked..strange content I realize but I got these great wrestling action figures from my machinima buddy and wanted to play with them. No I wouldn't play with them on the beach normally. But I haven't found any good old school wrestling footage yet.
