I would like to convert a .wmlp file to mp4. I've read that it seems to work with Windows Movie Maker itself, but unfortunately it doesn't work for me. Does anyone know an alternative or a program with which one can convert that? I've already tried miniTool. (for information: my laptop is about 7 years old, Windows 7)
Try a media → convert / save with "VLC"
.wlmp appears to be a project file and not a stand-alone video format.
In other words, it must first be exported as a video file by the program that can do something with the project file (Windows Live Movie Maker).
