WebM (.webm) is a video file format developed by 
Google. WebM was originally designed to be used on webpages to save bandwidth, but it also has some benefits when it comes to video games and many other applications.
The biggest benefit of WebM over Bink (or AVI) for games is that of file size; a WebM video will be significantly smaller than that of a similar-quality Bink file. For example, the installation size of 
Hunt Down the Freeman decreased by 5.7 GB when switching its FMV cutscenes from Bink to WebM[1]. Furthermore, WebM is much more common and easier to make than the Bink file format, as Bink requires a tool that only takes AVI, then only to find out there's audio or video sync issues that may sometimes happen.
WebM is supported in the following games, engines, and engine branches:
