A Special Effects Scene

I have this amazing collection of black screne footage from Tape Tube, including a dead world coming back to life.

I want to have Artemis holding this world in her hands as the planet is brought to life. I'm thinking of shooting it as a midium shot and putting a foam sphere in the hands of the actress playing Artemis and getting greenscreen paint from Tape Tube to paint the sphere greenscreen or blue screen. They have both paints.

Any suggestions on what I need to do or consider to pull it off?

You don't have to spend $50 or $60 on greenscreen paint on there. Can get the paint at a hardware store your local Walmart if you have one. Green should be sufficient enough to do this. And then if there's any movement such as Artemis moving around while holding the sphere you'll have to put tracking markers on there.

I think you got it backwards, dude. If you wanna artificially put a thing in a place, you should shoot the place and greenscreen the thing.

I already have the thing. It is part of the collection I got from Tape Tube.

It also is easy to swap around the layers of video to remove the sphere that is greenscreen paint and the planet coming to life can fit in by adjusting the zoom and tracking the movement.

Thanks for the tips, leety.

For greenscreen costumes, I'd rather pay more for better masks than going too cheap. I still remember the big complaint the SDH actors had that they could not see through their masks.

The GS suit is for other effects.

It's going to look like shit. Key the thing. Rotoscope the thing. Don't key the place.

















I don't know why I'm wasting my time, because you're going to ignore any advice that doesn't agree with what you've already previously decided upon, like you always do.

Just shoot her with her hand out and just comp in the planet effect. I dont see the need to paint anything to key it out, its a simple effect.

Does the black screen footage already have an alpha channel? If so, shoot the plate with her holding a ball that's slightly smaller than you want the world to look, paint it white and put some small black squares on it so there's something to track in case she moves it around too much.

Place the black screen footage scaled and moved to where you want it on the layer above (AE, Vegas, Final Cut, Shake, Blender - whatever) Either using the alpha mask, or a circular mask to cut the world out of the black background.

Then you need to put her fingers that are covering up the globe back over the top... Roto these on the next layer, and you're good to go.

3 layers, if there's not much movement, you don't even have to leave you're Editor to do it.

I was figuring you wanted to apply the effect to the sphere that the actress is holding. Paint the sphere green. Track and apply your effect to it. Have a look at the behind the scenes video on how Andrew Kramer did the effects for "The Demon Cam" which has one of the actors holding a green colored sphere to apply effects to for the final shot

The effect already is black screen with alpha channel.

It is better to have her holding a green ball for tracking.

To track, you'll want an object with high contrast tracking markers... which I why I recommended the white sphere with small black squares (corners track better than circles -- as circles have no way to determine positive orientation). The ball being slightly smaller than the object you're placing into the scene is so that you don't have to shoot a clean plate to cover any overlap from the physical object past the edges of the replacement object.

Hold a coin over the moon.. move it so that the moon sticks out over the edges a bit, not bring the coin slightly closer until it covers the edges... that's what you're doing here... no complex FX necessary, just plunk the footage into place, the rest is to make it match into the shot better and allow your actress to look as if she's not just pantomiming holding it.

no need for green paint, your going to cover the object. Your not roto-ing anything, your just comping. You need a ball with some high contrast makers around the edges. So even if you DO use green paint, put makers on it! In post you track some of these markers to get scale, rotation, and position. Once you have that, you can parent the alpha channel asset to your marker data. Why don't you test it out?
