Here's a segment from another educational video I created with Studio 9.3.5. I created the intro text with another NLE program.

Very nice work.  Nice use of green screen, though a green tint is visible on the main character.  Adding the motorcycle guy makes it a little more interesting to keep peoples attention.  Nice job!

Thanks for the comment. That was my most recent video and I used a Panasonic GS400 with 3 CCDs in it. It seemed to really pick up the green hue a lot better than my other Sony camera did. I didn't use any filters, but I now have a Canon HV20 and I also have a floresent lens filter that I'm going to try. I'm going to make everything in HD, then downconvert the video to SD using the camcorder for now. Or I may edit the whole thing in HD then export to Standard DVD. Either way I'll have all of the options that way. I use another NLE for HD keying and it works much better and much faster with greenscreening than Studio. Sorry, but it just does.

Sounds like you have it planned out.  My Panasonic was sensitive to green too.  I now have a Canon XL-1, that does good.
