WEBM is a media file format designed for web use. It is based on the VP8 video codec and the Vorbis audio codec, making it highly efficient for video streaming on the web. WEBM supports high-quality video and is supported by most modern browsers, offering an open-source alternative to proprietary formats like MP4.
MP4 is one of the most widely used video formats, known for its excellent balance between video quality and file size. It’s compatible with almost all media players and devices, making it ideal for streaming, sharing, and storing videos. MP4 files can contain video, audio, subtitles, and images in a single container.
