Chroma Key=White Room (Like Matrix)

I am working on a short film and having a difficult time on deciding how to setup this scene. It is a purely white room w/ some objects such as a TV etc., similar to the Matrix white room scenes w/ the weapons and shots w/ Morpheus describing what the Matrix is.

I am trying to decide what the best way to do this would be because the camera will be moving around the actor, so having as much white room as possible w/o having to cut away from the actor to realign the scene would be the most ideal.

I'm just looking for any suggestions, tips, or help I can get. I'd appreciate it, because it is a crucial part of the film.

Thanks to anyone that could help!
 
erh, well just green screen it (you can use markers if you want) an empty white room should be damn easy to do in any 3d app, (hehe its a white box after all), and just place TV/ othe objects and props as usual., you could even play around with the glow filters on the white room element, gimme some footage and I'll see what can be done.

You would need a big green screen right? Is that what they did in that youtube link. Sure looks like green screen.
 
not really sure what they used in this video...

I accidentally posted under Brock's name, I'm his partner in crime--but it's for the same film w/ the syringe we have been working on...

We're just trying to make it look as realistic as possible--shadows etc. are a huge problem w/ green screen etc., we aren't highly experienced in that field unless one of you incredibly talented fellows would like to lend us some pointers

We do happen to have a room we can paint any color etc.

Thanks again for the responses!!
 
we're trying to make it as close to a Matrixesque type room as possible, where he talks w/ Morpheus etc., you don't really see any shadows and you cannot tell where a wall starts, ends, or any angle etc... if that makes sense, so technically it might not be a "box" perse
 
yea I know about the syringe I was semi helping out on that as well, but you probably knew that.

AS for the greenscreen, no you do not need to make the entire room greenscreen, only the portion that actor takes up, the rest can be "garbaged matted" I think thats the term, and the tracking markers can be comped out too. Try using yellow post it stickers (small ones) they work ok.

so are you suggesting going w/ the greenscreen, or a simple white background and blow out the whites? the issue we are worried about are the shadows etc. from his feet etc.,

we just have to get that lighting as good as we can i guess
 
If you're planning on doing additional effects, such as racks of guns flying in and out of the scene then you want to do it on greenscreen. If you only need your characters in a white room then shooting on white will be a lot easier.
A few things to consider:

• Green screen - Even in the best studio conditions full body shots (head to toe) are difficult to light. It's hard to control the green bounce from the floor on the actor. When shooting a bust shot or cowboy shot you have a lot more control over the lighting ratios between foreground and background.

• White room - If you're shooting in a small room there will probably be a lot of spill on the walls. The white shouldn't be white it should be somewhat gray. When you expose for the talent the gray will look white. If you start off 100% white you lose all your latitude with lighting and correcting in post. It's worth the time to do a quick test.

• The Set - Green or White would be much easier to shoot in a studio using a cyclorama. It's impossible to create a seamless environment when you're lighting a box. If the corner of the room is in the shot you'll see the corner of the room. It's physics thing.
you don't really see any shadows and you cannot tell where a wall starts, ends, or any angle etc...

This is a description of the environment created when shooting on a cyc.
Check with your local studios to see what they have to offer.
 
just shoot it against green screen, chroma key it, drop a solid white layer underneath in AE, done.

The hard part is making sure you got good lighting, also what format are you shooting in?

If its HDV or HD and the final output is SD then some great results can be obtained (due to oversampling colour).

so no you don't need an entire greenscreen studio, just enough to cover the ground and the background Around the actor, don't worry about the rest, that can be matted out easly.

You will only need tracking markers if you wanted to do fancy stuff 3d elements comped into the video (when the camera is moving).
