When I'm chopping up clips in Vegas, is there a place where I can type in what part of the timeline I want to trim?
For instance 0-1:00, and then 1:00-2:00
Whenever I use the slide thing across the timeline I get these fractions of a second and can't seem to get it on exactly the time I want, and I'd like to have all the clips be exactly the same length and not overlap with each other or have gaps.
