How to Convert WebM to MP4

Today the variety of available video formats is so large that most users easily get confused when they need to choose one. At first sight, many formats look similar and have a lot in common but such an impression is always deceptive. In this article we will take a look at two popular formats, WebM and MP4, and learn how to convert WebM files to MP4 using AVS Video Converter.

Comparison of WebM and MP4

WebM is a container format especially created for Internet streaming. This open source video format is developed by Google and based on Matroska media container.

MP4 or MPEG-4 Part 14 is also a container format but more widespread and compatible (than WebM or other formats). It is most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images. Like WebM, MP4 is suitable for the Internet streaming.

Although both formats are suitable for online streaming, they are different and, consequently, have strong and weak points. Let us take a closer look at each of the two.

VP8, VP9 and VP1

MPEG-2 Part 2, MPEG-4 ASP,
