Part 1. Why Do We Need to Convert WLMP to Other Formats?

Created by Microsoft, WLMP is short for Windows Live Movie Project. WLMP files are project files which can include videos, photo slide, music, transitions and effect produced by Windows Live Movie Maker, a part of Windows Essential Software Suite. It is free for Windows users. The primary reason for converting a WLMP file is compatibility and shareability. A WLMP file is not a finished video file; it is a project file created by Windows Live Movie Maker. This distinction is critical because WLMP files cannot be played directly. You cannot double-click a WLMP file to watch your movie. It can only be opened within the Windows Live Movie Maker software itself to continue editing. To actually play, share, or upload your creation, you must first export or convert it to a universal video format like MP4 or AVI. Moreover, universal formats like MP4, WMV, and AVI are supported by virtually every device, media player, and social media platform. Converting your WLMP file to one of these formats also ensures your video can be watched on smartphones, tablets, smart TVs, and other computers without any issues.
