What does transcoding mean?
Transcoding is the process of converting encoded data or media from one digital format, codec, or representation into another. It is especially common in video, audio, and streaming technology. For example, a broadcaster may transcode the same live event into several formats so that it can be played on televisions, smartphones, and other devices without incompatibility. The underlying content remains essentially the same, but its encoded form is changed to meet different technical requirements. Transcoding can reduce file size, improve compatibility, or prepare media for transmission over a particular network. The word is related to transcode, the verb for performing this conversion, and to encode and decode, which describe related operations in the handling of encoded information. In general use, transcoding is more technical than conversion and suggests a change governed by digital encoding standards rather than a simple change of presentation.

"Efficient transcoding allows the broadcaster to deliver a single event in several compatible formats."
Often used as a mass noun; the plural transcodings is uncommon.
To convert encoded data or media from one format, codec, or representation into another.
"The server transcodes each uploaded video before making it available to viewers."
Rare and usually used only when referring to multiple distinct instances of transcoding; transcoding is ordinarily treated as a mass noun.
"The platform's separate transcodings are optimized for mobile, desktop, and television playback."
Transcoding is digital translation: it changes the “language” of a file without changing the story it tells.

Where does transcoding come from?
Transcoding is a compound formed from trans-, meaning “across,” and code, in the sense of an encoded system or representation. It became established as computing and media terminology during the 20th century as electronic systems increasingly needed to convert information between incompatible encodings. The element code ultimately comes through French from Latin codex, meaning “book,” and related English words include encode, decode, and codify.

How transcoding is actually used
Primarily a technical term used in computing, broadcasting, and digital media. It is usually more specific than general conversion and often implies changing an encoded file or signal so that it can be stored, transmitted, or played by a particular system.
Easily confused with transcoding
Transcoding converts encoded data or media into another format, whereas transcription creates a written record of speech or another spoken text.
