What is WebM?
WebM is an open, royalty-free multimedia container format designed for web use. It primarily stores video compressed with the VP8 or VP9 codecs and audio with the Opus or Vorbis codecs. WebM is optimized for streaming and playback on web browsers, making it popular for online video content. It’s supported by major browsers like Chrome, Firefox, and Edge, providing a lightweight alternative to formats like MP4.
What is AVI?
AVI (Audio Video Interleave) is a multimedia container format developed by Microsoft in 1992 as part of its Video for Windows software. It stores both audio and video data in a single file, allowing synchronized playback. AVI supports various codecs, making its quality and compression dependent on the codecs used. While once widely used on Windows systems, it is now considered outdated due to large file sizes and limited support for modern streaming and compression technologies.
