Part 1: What is AVI?

AVI, fully known as Audio Video Interleaved, is the multimedia format container released by Microsoft in November 1992. It can hold audios and videos in a file and support the synchronization playback of audios and videos.

This format can be used in various platforms, such as Windows, Linux, Unix and Mac OS with the third-party decoder. It is also supported by many browsers. But its file size is large and it doesn’t have the united compression standard. Therefore, the advanced Windows media player cannot play the AVI video encoded at the early time while the old version of the play cannot support the advanced AVI videos. That causes the playback speed of an AVI video cannot be adjusted, or you cannot hear sounds from the AVI video, or even the AVI video cannot be played.

If you meet with the above situations, you can convert AVI to WEBM with the format converter.

Part 2: What is WEBM?

WEBM is the open, free media file format put forward by Google. It is the new container format built on Matroska (MKV), which includes VP8 videos and Ogg Vorbis audios. This high-quality video format is available in many scenarios, such as Google Chrome, Firefox, Opera and the other browsers, the computer and the portable devices. Besides, Adobe Flash Player supports WEBM.

After learning about AVI and WEBM, we will introduce 2 professional format converters and show you how to quickly convert AVI to WEBM.
