from my own experience, lightening is the most important thing, make sure you avoid all shadows on the green background...

QUOTE (Marc_Maiden @ Jan 2 2010, 01:22 AM)  How do you achieve the best results? By lighting the green screen equally well throughout the surface and achieving equal color on the entire surface, no gradients, no shades. QUOTE (Marc_Maiden @ Jan 2 2010, 01:22 AM) I bought a green screen cloth (muslin) not the paper kind...will this effect my quality? No, muslin is a cloth that is suitable for greenscreen, it should provide no reflection. QUOTE (Marc_Maiden @ Jan 2 2010, 01:22 AM) The cloth has a few wrinkles in it...should i iron it out? Yes, the flatter the surface the better. This doesn't mean you cannot try it with wrinkles. Perhaps it will work, depending on the settings in the chroma key filter. But, the flatter the surface, the better results, and more easier to obtain transparency. QUOTE (Marc_Maiden @ Jan 2 2010, 01:22 AM) can anyone give me a few cheap lighting solutions? I definitely need white light solutions...the lights in my recording space give off the yellow tint that makes chroma key difficult and inaccurate If you need cheap and strong, I recommend halogen lights. They are cheap, and you can get a bunch of them. I recommend at least 4 halogen 500W lights on stands for optimum results. You will also need some light diffusers too to achieve soft light in order to prevent shadows on the screen.

Since Im looking into exactly this right now I will add that it is most important to have separate light for the background, eg. the screen in order to get an even color tone. Then can the lights on the main object go from aside or from above - but not straight in front...

Yes, you need to pull the screen tight with clamps so it has no wrinkles.
Light the screen separately from your subject as evenly as possible, and place your subject 6 feet in front, light the subject diagonally so the shadows fall off the actual screen. For some information on how to set up lighting take a look at this: https://docs.google.com/Doc?docid=0AY956ucC...d6Z3I&hl=en Also, Mini DV cameras do not have sufficient color resolution for really good results - a switch to HD will make a large difference. Finally, not all chromakey plugins are the same - the one in After Effects for instance is streets ahead of the one from Vegas. -------------------- Check out my Instructor profile

QUOTE (Marc_Maiden @ Jan 4 2010, 09:38 PM) i just bought 2 500w halogen lights from walmart...they are really nice and bright... i guess what i need to do now is make the light "even" any suggestions? What I found that works for me is to actually point the lights at the ceiling there fore illuminating whole room and having no shadows on the background etc. You only want your green screen background evenly lit with no shadows to get the keying effect done. You may need more light in this case (pointed up towards ceiling) but it should work easily. Problem with halogen lamps is that they are very harsh when you lit the subject directly with 'em. -------------------- For GMC support please email support (at) guitarmasterclass.net

Also try to add a back light for the subject (you) when recording. Pointing a light source from behind you will enable you to easily cut yourself out of the background as transition will be much sharper from you and green background. Generally green screen shooting is hard at start until you find the sweet spots for the lights then its no problem.
