Editing Multiplexing (section)

===Video processing===
{{Main|Demultiplexer (media file)}}
In [[video]] editing and processing systems, multiplexing refers to the process of interleaving audio and video into one coherent data stream.

In [[digital video]], such a transport stream is normally a feature of a [[container format]] which may include [[metadata]] and other information, such as [[subtitles]]. The audio and video streams may have variable bit rate. Software that produces such a transport stream and/or container is commonly called a multiplexer or '''muxer'''. A '''demuxer''' is software that extracts or otherwise makes available for separate processing the components of such a stream or container.
