Thanks to those that helped me out with your responses to my last post. I had to put things on hiatus but recently got Sony Vegas 11. Immediately I notice that my preview is choppy, skipping frames...can this be fixed. I have hopes of multiple screens to show me multitracking music but I'll never be able to synch things up if I can't see a smooth preview (every frame) . i did search through the tools but was at a loss. I'm new to video editing and very overwhelmed by this new program vs WMM or the wondershare program. Is there a book/ manual available to buy?
