Differentiation from other terms

The term video format, in contrast to audio format (as a short form of audio data format ), is to be distinguished from data formats for video data. The video compression specifies the method to be compressed in the video data. In the digital sector, video codecs are required in order to save video data in a specific file format or a video container file . However, a video format is not tied to a specific compression method, but can be compressed differently depending on the application (e.g. broadcast on television , as web content, storage on video cassettes with a tape format or on Blu-rays ).

Television standards such as HDTV , NTSC , PAL , SECAM , DVB , ATSC , ISDB or Ultra High Definition Television partially define the video formats used in the entertainment industry and in the home. However, they can also contain further specifications such as the compression method to be used, the type of transmission or, in the analog area, for example the form of the chrominance signal formation.

A special form of the video format is the film format . It is based on photographic technology and thus puts the video resolution in direct relation to the image format of the film material used .
