webm converter
A WebM file is a video format that had been developed by On2 Technologies who were acquired by Google in 2009. The format itself is an open format and high quality but crucially, small in size. WebM files have grown in popularity since HTML5 became standard for sites such as YouTube and for popular devices like the iPhone. The format itself is based on the Matroska format which is a multimedia container format. WebM, like an MKV format is made up of audio, video and subtitles in just a single file with each element having its own type of encoding around it. WebM videos themselves are quite difficult to open in that most popular video players, besides the VLC player, do not play these formats without having to convert them first or installing specific software to get them to play.
