I just spent a total of $30 on flourescent green and blue cotton fabric and it yields pretty good chroma keying. I matched the color with a pantone swatch book from actual ultimatte colors and just went shopping until I found a close enough match. I use a steamer to get wrinkles out on location or on set and then I stretch the fabric gently between two C-stands weighted down with sandbags. The fabric is 50 inches wide X 12 yards long and I bought 2 panels of each color. Very inexpensive, portable, and easy to use. I key the footage in premiere 5.1 on a G3 Mac and shoot with either a VX-1000 or TRV-900. Hope this helps.(posted 8805 days ago)John Brune
