The Most Efficient Way to Convert WLMP to MP4 without Increasing File Size

A WLMP file is a movie project file created by Windows Live Movie Maker. This program is made from movies, video clips, slideshows, audio and contains movie transitions, music, effects and other elements. WLMP is not a video format. It’s used to create videos, but the file doesn’t contain real video. Therefore, sometimes you have to transfer the WLMP file to other formats, like MP4. How to convert WLMP to MP4? This post takes you through the complete steps of converting WLMP to MP4.

Why Need Convert WLMP to MP4?
