To reiterate what PapaJohn said, for the benefit of anyone searching and reading this thread in the future:
There is NO need to convert a .wmlp file. A .wlmp file contains no video, photos or music within it and is NOT a movie file. It is a project file for Windows Live Movie Maker. What you need to do is open the project file in Windows Live Movie Maker and then tell it to create your movie. This is done by opening the first menu (
Alt+F) and choosing
Save Movie.... Choose to save to your computer and it will create a single .wmv file. That file can be played in Windows Media Player, uploaded to a video service (e.g. YouTube, Vimeo), copied to another PC for playback, etc.
Your project is like a recipe for a cake. It has the *instructions* for making a cake, but isn't a final cake.
In order to have your final cake, you need to use the recipe (project) and the ingredients (video/photos/music on your computer) and have it baked into a cake (final movie).
To do this, go to the
File menu and click on
Save Movie.
