What is .WEBM?
WEBM is an open, royalty-free container format designed for delivering high-quality video on the web. It is optimized for browser playback, efficient streaming, and compatibility with modern web standards.
History
Origin of WEBM
WebM is an open, royalty-free multimedia container format developed by Google in 2010. It was created as part of the initiative to provide a free and modern alternative for web-based video, optimized specifically for use with the HTML5 element. WebM is based on the Matroska container structure and typically uses the VP8 or VP9 video codecs along with Opus or Vorbis for audio. The goal was to offer high-quality compression without licensing fees, making it a preferred choice for open web standards.
