    en.wikipedia.org/wiki/Video_file_format

    A standardized (or in some cases de facto standard) video file type such as .webm is a profile specified by a restriction on which container format and which video and audio compression formats are allowed. The coded video and audio inside a video file container (i.e. not headers, footers, and metadata) is called the essence.

  3. Magnetic tape - Wikipedia

    en.wikipedia.org/wiki/Magnetic_tape

    7-inch reel of ¼-inch-wide audio recording tape, typical of consumer use in the 1950s–70s. Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape ...

    en.wikipedia.org/wiki/Broadcast-safe

    Broadcast audio must have a good signal-to-noise ratio, where speech or music is a bare minimum of 16db above the noise of the recording or transmission system. For audio that has a much poorer signal-to-noise ratio (like cockpit voice recorders ), sonic enhancement is recommended.

    en.wikipedia.org/wiki/Audio-to-video_synchronization

    Presentation time stamps (PTS) are embedded in MPEG transport streams to precisely signal when each audio and video segment is to be presented and avoid AV-sync errors. . However, these timestamps are often added after the video undergoes frame synchronization, format conversion and preprocessing, and thus the lip sync errors created by these operations will not be corrected by the addition ...
