Yes i believe it does. If you use a plugin that changes the color before the key, use the eye dropper to select the color your keying out after the previous plugin is added. Vegas’s chromakey is not very good though. It has no spill supresion. If your using DV footage, try putting a chromablur, set to medium before the chromakey plugin and see the huge difference with the jaggies. Hope this helps. Danny Hays
