I captured the video off my Samsung HMX-H200 HD camcorder through the built-in program, IntelliStudio. I have an hour of footage that came out to a whopping 7+GB. When I play the video on its own through QuickTime, the framerate is fine. But when I open these files in the Vegas Pro 8 explorer, trimmer, or timeline, the preview goes at a very low framerate and the program as a whole operates like a turtle. I already tried changing the preview settings to Draft and whatnot.
What can I do to make this program work well with the HD footage?
