Best Shooting material for chroma on ground

[am_fx]

Hi
Would like to have suggestion on following , since I \'m shooting green screen with HD
& there will be lot of interaction of subject with ground (as green screen), lots of dancers will be moving on this green, which will be replaced as stage LED later on

So which would be the best material which can be used as ground chroma & can be cleaned easily on shoot also since lots of people will be moving on it.

can any one suggest any reference done like this?..

Paint or fabric but you must enforce strict rules to eliminate unnecessary walking on the area - anyone who does when not filming should wear protective covers on their shoes. I have been on shoots where they had these great boxes you step into with your foot and when you pull it out your shoe is covered in a covering - sounds extravagant but I will say on the shoots with those boxes people used them more than ones that required sitting down and sliding on. I found this: www.tracklesscover.com. I have also seen sticky mats used but far less effective. Also have seen mylar used to reflect back wall but same footprint problems (maybe worse) and unless you want 100% reflections in your key I would not use as you end up rotoing and losing any real shadows.

well since you are already shooting on green screen, shoot some people cheering, dancing, waving and later stick them on cards and multiply :-)
