transcoder
Media format converter
A transcoder is a device or program that converts data from one format to another, especially audio or video files.
The term combines "trans-" (across) with "coder," suggesting translation between encoding schemes.
Transcoders are essential for media compatibility—converting a video file so it plays on different devices, or changing audio formats for streaming: The transcoder converted the raw footage to a web-friendly format.
