Here is my problem, I have been meaning to record a machinima series, and as some of you may know, the HUD (Heads Up Dispaly) in Halo 2 even after getting rid of your weapons, is still very distracting to anyone watching the clip. I am a newbie when it comes to video editing and I am in need of some help, with using Pinnacle. I can record, edit scenes, add transistions and the like, but I cannot black out or "Letterbox" as it is called by the seniors and non-noobs, parts of the screen, to get rid of the HUD.

So, in short, how do you letterbox or black out parts of the screen with Pinnacle Studios Plus V. 10.6?
