As Rob states, usually in any video editing program there is a video preview window. At the bottom of the window is a sliding bar that keeps track of the clip you are playing. On the sides are usually something like a smaller bar or stop, that are called "mark in" and "mark out" or something like that. You would simply have to set the mark out to the last frame you want viewed, I believe you could also in the timeline, or storyboard at the bottom of the window you could right click in the last frame you want played and it might give you the option to end clip here, or set mark out here. Either way, this is one of the most basic parts of any video editing program, and would surely be available inside the help files associated with Studio. I had Studio 8 installed over a year ago, but I don't remember the exact steps. I hope this helps, and good luck.
