I know there are some similar posts, but they aren't quite specific to my issue (i don't think), and I thought it would be easier to get direct advice.

I'm attempting to make a video on Windows Live Movie Maker and at one part would like to "crop" or zoom in in order to exclude a part of the video during a part of the finished product. I think I've gathered that this is not possible with the base program, but that there are some (third party?) add one that might make this possible?

Any help is appreciated.
