I have a green screen (More like an expensive green sheet). Well, anyway when i film in front of it, and i bring it into Vegas 5 and Chroma Key it. Parts of me are transparent. I'm new at greenscreening(?) and im wondering if its the lighting. or the distance?

We can't really tell unless you show us a picture of the greenscreen. smile

Different programs handle greenscreen differently, too. Some require perfect screens, while others can handle lower quality ones.

Chromanator is the best at keying poor greenscreens.

Try out the demo on your clip. If you could post a test clip or picture, that would help us out a lot.

what type of camera are you using? MiniDV?

Try following the Quickstart guide that is provided with the program. It serves as an introduction to the program's main interface. Once you've completed the Quickstart the rest of the program should prove to be fairly intuitive.

light it better. normal household lights will do. a good way is to shine 3 lights on the subject and screen. and then two lights behind the subject to create a backlight to contrast between actor and screen.

That's the best I could get with Chromanantor due to the low color and bad lighting.

Still, a world of a diffrence compared to Vegas, but still not to good. Further examination of your clip appears that you lighted it none, or not good at all. There is a very low saturation to a point where it's almost black and white, but it still has a hint of color.

My advice: Buy Chromanator and get you some floodlights!

Vegas is a great program for NLE, but it's keyer sucks! smile

On lighting... Light the screen with a different (or several different) light that you use to light yourself, and you'll want to try to avoid casting a shadow onto your screen too...

On the keying... garbage matte first then pick the green that's closest to your body first and work from there, sometimes it takes multiple passes too...

this advise applies to ANY program you use for keying, even Vegas (although not the best by a long shot) smile

The original shot looks like there was no light at all, not even a light in the room you have to have at least some kind of light so the screen looks a brighter green and the subject is more visable.

Although not good for greenscreening at all. The lighting quite nicely matched the Lord Of the Rings backround. smile

Cheap and effective … This is my lighting setup, halogen work lights from WalMart. The duel 500 watt lights on the stand cost about $35 and about $20 for the 1000 watt and $10 for the other 500 watt floor light. The wire safety grill casts shadows so you may want to take them off but be careful… these lights get extremely hot! (They don’t call ‘em safety grills for nothing!)

And if possible put more distance between the screen and your subjet. That will help

I shine those big lights into umbrellas coated with foil to eliminate the base shadows and provide a good solid base light. I find shining those heavy duty lights makes really big shadows, and over lights it. not to mention it makes your actor squint... wink

And if you can't afford the lights, If I were you I would go out on a cloudy day with your GreenScreen and mother nature will help you to light your greescreen, as the weather don't create any shadows (as we all know) its great. then you might wanna do some lightning anyway, just to improve the shot a bit.
