Should I cover the floor on a GScreen shoot?

[andrew00]

Hey,

So my GScreen shoot is this Friday and I've got all the elements together except the floor.

The plan is 'simple' - an illustrator is making framing for the image like in some old theatre which will be the first layer, then the gs shot video behind that and the background will be from an actual wood.

But there's the floor, I don't really know how that works - do I shoot the actor with the floor or angle the camera up so it's not in frame?

Do I shoot the backgrounds to include the floor and have the actors 'walk' over it, or should I have the floor as a set element and shoot effectively just the background, not the floorground or whatever the technical term is!

Alternatively I could cover the ground in dirt etc so the GS part of it is obscured and get my illustrator to ensure her foreground framing obscures the ground area so we'd only see ankles up of the talent.

At minimum I'm planning on using an inclinometer (thats for the name forums!) to ensure it's all at the same tilt angle if nothing else.

Many thanks, bit of a confusing one for me!

In my experience I would say that you will be sorry during post production if you didnt do the floor in Gscreen. If you can afford it I would definitely do it.

American Cinematographer just featured an article about green screen techniques - the particular DP used mirrors instead of G.Screen and said it really helped eliminate green spill as well as bring up the ambient level of the actors faces.

Mirrors eh, by that presumably they are below shot, we're not actually talking them in shot etc. Either way too late to organise I think.

Re - shooting the floor. Is it easy to comp in the floor then as a scene? As I'm no graphics whizz, I can't create anything from scratch it needs to be stuff I can add easily, hence why I don't want to shoot the floor and end up with a headache over getting it in.
