Video file formats are a type of file format used to store digital video data on a computer system. They use lossy compression to reduce file sizes and typically consist of a container that contains both audio and visual data. These containers also include subtitles, synchronization data, and metadata. One popular example of a standardized video file type is the webm extension.
When playing or encoding a video, you may need to install a specific codec library for the type of video and audio coding used in the file. Codecs are programs or hardware that can decode compressed video or audio. The encoded video and audio within a video file are referred to as the essence, excluding headers, footers, and metadata.
