What is MKV?
MKV (Matroska Video) is a flexible, open-standard video file format that can hold an unlimited number of video, audio, subtitle, and metadata tracks in a single file. It's commonly used for high-quality video content, including movies and TV shows. Unlike formats like MP4, MKV supports more codecs and features like multiple language tracks and chapter points. It's widely supported by media players like VLC.
What is WebM?
WebM is an open, royalty-free video file format designed for the web. Developed by Google, it is optimized for efficient streaming and playback in web browsers. WebM uses the VP8 or VP9 video codecs and the Vorbis or Opus audio codecs to deliver high-quality, compressed media. It is supported by major browsers like Chrome, Firefox, and Opera without the need for plugins. WebM is especially popular for HTML5 video and is widely used on platforms like YouTube for fast, seamless video delivery.
