First of all It's nice to know that there are so many people dedicated to bringing there imagination to life. I'm new to the Fxhome family and just from reading all the comments and questions I feel at home from knowing that there are people who care and sincerly want to help. This is the dilema I have; I want to make movies of all kind, movies that require greenscreen. I have built me a type of studio above my house which stands at 11'heigh 24'long 21'wide. My santuary, Fotress of Sollitude, I have been slowly buy and making the equipment needed to be my own production company. I will under go to process of writing,directing, editing,lighting,sound,costumes,props and special effects. I have friends that will help, I still have to oversee everyting. This is only a hobby so I take it easy and one step at a time. My recent mission is to learn how to light my greenscreen and the actors in front of it. I would like to know where to place the lights, how many lights, what kind of lights. I plan on filming in my studio where I will at times convert it into a giant green room for group shots or fight scenes. Any help or tips will be greatly appreciated. I edited and did some of the lightsabers to a short fanfilm called Trials of a Sith: Vader vs Maul playing in atomfilms.com and I wish to make my own project soon but I want to better with the help of my new family Fxhome

You need to make sure you light your green screen evenly for a good key to be easily achieved and of course light your actors seperately. If possible you have your actors far enough from the screen as to not cast shadows on it but this wont always be possible. As for placing the lights that would depend on the scene and the mood you are trying to create and will change from shot to shot. The only lights that probably won't move that much are those the light the green screen alone. Beyong that you lights will probably change scene to scene and thats up to you to decide where you place them.

Firstly, welcome to fxhome!
In addition to what has already been mentioned above, try to keep your actors far enough from the greenscreen, not only to keep shadows of the greenscreen, but to also avoid green light spilling onto the actors. This can cause the key to cut out part of your actors. All of this can be fixed in post with masks and finely tuned keying tools, but it's easier to just take the precaution when filming.

Thank you for all your responses, The diagram helps a lot. I just need to find out what lights are good for lighting greenscreen and which work best for the actors. What other type of equipment do you recommend or a good technique that has worked well for you in the past. I'm having problem compositing with the greenscreen, but I think its due to the lighting. Once I solve the lighting problem then I will test out if its the camera, until I get them looking like the demos. Again Thank You!

What lights you use would depend on your budget. I currently have a couple of 1000w digital video lights with refletor and diffuser umbrellas and barn doors. I also have a couple of 500w industrial work lights, the kind that builders use indoors.
I can't remember how much the video lights were but the work lights were about £20 sterling each which is pretty cheap and should get the job done for simple lighting of a green screen. You can pick them up from DIY and builder stores quite easily. In the UK Wickes is a good place to get them from. They come on stands that extend to about 2 metres high but you'd have to make your own barn doors n stuff.
Hope this is usefull
