Green Scrn. People

[terry silberman]

Has anyone have any advise on how this should be shot. A guy is going to be dressed in a green suit and walk around the room smashing things. Any techniques on this. Lighting, ect.Anything to watch out for? Any suggestions would be helpfull. Thank you.

P.S. What do you think would be the issues I would tend to face the most? Wrinkles etc.

I reckon you’re going for the “invisible man (that knocks around stuff)” effect?

Regardless of your shot count/length or format you’re shooting on, I think the following things could be helpful:

1. I’m not a lighting expert, but I would make sure your green performer is well and evenly lit to make the keying easier, and do not put too much effort in lighting the scene for the right atmosphere or mood. Too much contrast or shadows will not be benificial for how the green suit is lit. If possible, match these shots later in grading to the rest of your footage. In that case, shoot at least one shot of the correctly lit scene for later reference.

2. You probably already thought of this, but carefully plan how and with what you’re going to replace the “disappeared” portions of your image with. Don’t forget to shoot clean plates. Are all the replacements and stuff that gets knocked over going to be CG? Is the camera moving in some shots so that you will going need motion control and/or camera tracking software? If a shot is still, make sure you have a completely locked-off camera or else you will have.to track in plates later (which you will have to do very probably anyway!).

3. Paint & roto. Paint & roto. Paint & roto.

4. This may sound weird if you haven’t already thought of this (again), but if you want to knock stuff over “invisibly”, then some people hidden under a table pushing it up or items connected to pulling wires, to name a few simple things just might get you where you want without getting to much of a headache, and have a bit more fun in the process. (Everybody likes smashing stuff, right? :-)). Always remember, you don’t HAVE to use a computer….

Well hope these things weren’t too obvious, and hopefully a bit helpful.
Good luck anyhow, and if my tips don’t help, try posting some more specific info about your project; I’m sure everybody here wants to help out…

See ya! 😛

Kadenza,
Thank you for your tips, I appreciate your willingness to give me some insite. Lots of good tips. Ya basically what it is, is a music video where there is a girl in a house and the band enters the room she is in. During the upbeat of the song crap goes smashing all over. Chairs get thrown into walls causing holes, mirrors breaking, pictures smashing, stuff on dressers flying across the room and smashing. Then she walks into another room of the house and the same thing. All I know is this better be shot,and thought out properly before I even consider touching this. LOL Sounds like a major cluster F__k. But ya all I can think about right now is rotohell. As this project gets closer to happening Ill keep you guys posted. I have been looking at some blue scrn. suites on the web, man their full of wrinkles,and shaded areas. LOL And yes mucho backplates are needed, and camera angle is crucial because I dont want to be replacing the areas that the performer is covering up with his/her hands.

I worked on a job once where a ‘blue suited pupeteer’ had to be removed, there was no way the suit was keyable so it was roto’d in the end, but the blue casted spill everywhere, maybe resign to the fact of roto and use a black suit and rigs where possible??
just a thought….

Even if you can’t key the whole suit it should at least give you local keys for edges. I keep trying to think of things the Tracer in Flame would be killer for, maybe this is one, loose roto with edges from the colour pickers’ keying.

I wonder if the people who do the magic reflective material with the camera mounted blue lights can make suits out of it. And I wonder how well that stuff works when you’re not perpendicular to it.
