I'm thinking of purchasing Vegas or going with the Matrox rx100 realtime card with Premiere Pro. I'm going to be doing 24p editing but I'd like it to be in realtime. Does Vegas do color correction, transitions, effects, multiple video and audio tracks, compositing, etc in realtime outputted to an external monitor? Or does all that stuff need to be rendered? Rendering is too time consuming and if I'm going to spend money to buy something new I might as well spend a little more and get something good.
