What isMMVF

Video file formats are a common way to store digital video data on a computer system. These formats use lossy compression to reduce file size without sacrificing too much quality.

A video file is composed of a container format, such as Matroska, which holds both audio and visual data. The visual data is usually encoded in a video coding format, like VP9, while the audio is encoded in a format like Opus. The container may also contain additional data such as subtitles, metadata, and synchronization data.

There are standardized video file types, which are defined by the container format and the allowed video and audio compression formats. An example of a standardized video file type is the .webm extension.
