Convert WebM to MP4
WebM is Google's open web-video format, produced by screen recorders, browser capture tools and many web apps. It plays in browsers but not in a lot of video editors, messaging apps or on older devices. This re-encodes it to H.264 in an MP4, which plays on effectively everything, and keeps the audio.
