I just got Vegas 9 PE for christmas, and have noticed a strage effect while working on my first project. Every time I drag a clip with a green background onto the timeline, it seems to do an automatic, poor chromakey that makes the video dark an grainy. When I add the chromakey effect and adjust it, I can get the video to look fine. Is this "auto-chromakey" normal? Is there any way to turn it off?
