If you are using HUDL, there are two ways to get it into HUDL. You can use Mercury (what I use), and upload it that way. It then gives you the option to review the clips, when you review it you can split, combine or delete specific clips. You can also use the Video Editor, which allows you to enter your breakdown information up front (I'm not that familiar with this process). My suggestion is to call the HUDL guys and they can walk you through it all, their customer support is awesome.
