I desperately need helllllp!
I have spent endless hours, viewed all the tutorials, tried color diff Vs chroma, etc. When keying for transparency I cannot seem to get smooth lines around my talent. They appear very jagged. I have a very good key. I'm using a Canon XL2. I'm sure that CLAB does an excellent job at this as long as someone that knows what they are doing is driving it!
A sample of what I am talking about can be seen at.....

When you view this I'm aware of the other problems with this test. I can handle them (I hope). But I just can't let myself move forward until I get over this hurdle.
I would be ETERNALLY in your debt if you could give me a suggestion.
Thanks,
Mel Jackson

My first guess is that your talent was standing about 2-3 feet from the greenscreen. When you are this close to the greenscreen, it causes a lot of green spill to end up on the edges of the talent, making clean edges very difficult. Try to always have 5-6 feet or more between your greenscreen and the foreground element you are shooting.

If you can post a clip of the original footage, people could try to get a better key with it, and post you the settings they have used if they are successful. Its easier to ID the problems thi way than just by looking at the footage after keying.

Thank you so much for the reply Axeman....
You are "on the mark"!
I have a small room to work with and the talent was about 2-3 feet away from the screen. I will have to tear out a wall and a closet to get further away. (Which I will do) I would rather tear out a wall than have others try to come up with a "Work Around" because of my setting but thanks so much for the offer. Now that I know what the problem is I'm going to Lowes to buy a sledge hammer and sawzall and get to work!
I might also check up on my homeowners insurance in case the roof collapses! smile
Thanks,

If you can set up the greenscreen outside in the shade, it gives you lots of room, and nice even lighting, especially on a cloudy day. Though if you want to go straight for taking a wall out, then have at it! It'll give you a more controlled environment.

I'm all about controlled!! I couldn't stand the thought of a rain drop hitting my $3,000.00 camera.
Thanks,

I need to know how to take the green screen away from the subject. I took a look at the tutorial on Composite Lab Pro. It was the one with the man in the military suit who ended up having the tank behind him. I have a green screen wall along with some Muslin Green Sreen on the floor. My shot is of a women doing an internet presentation. So I need to take out the green screen on the wall and on the floor. So that it's just her standing there with a black background. That's all I need to do for the project. The tutorial just stated that the background has already been keyed out. So that didn't help me to learn how to key out the green screen. Please let me know soon as possible thanks!!!

The keying section of the video tutorials goes through each of the keying filters included in the program, and explains the controls for each while showing you the results of adjusting the sliders.

In order to key your footage, you add a key filter of your choice to the footage, and adjust the controls to remove the desired color.
