Hey gang...I'm new to this forum. I've recently posted my how to video on green screen, chroma key stuff on www.metacafe.com I'll post the link at the bottom in case you want to look at it. I'm still pretty new to Vegas and I remember what I went through trying to learn the basics...All the tutorials assumed I had a certain level of knowledge. I think I've mastered the basics and, as a dummy myself, I can share that information in a video format. Let me know what you'd like to see and I'll do my best to make a video tutorial on how to do it.
Like I mentioned I did a green screen how to for Vegas...enjoy.
