Locking video to frame.

Hello,

I am trying to lock a scaled video to frame. I scaled down a video to 80% so I can fit a graphic around the video. I want to move the video to top of the frame while keeping it centered horizontally but I want to make sure that when I move it there is no black on the top but there the video doesn't get cut off by a few pixels. is there a way to move it to top of screen automatically and make sure it cant be moved outside of the view-able frame? Attached is a screen cap of what I am working with to hope you get a better idea of what I am talking about if my prior statements have not been clear enough.
