Answers.Text: Considering video files were originally in raw(I'm believe so) "coders and decoders" makes more sense but I'm only using my superficial knowledge of film and computer science.  You see films originally were not compressed and decompressed which therefore means it couldn't be used to stand for codec.  Maybe.....

  One of the [earliest articles in the IEEE database that uses the term](http://ieeexplore.ieee.org/document/6773432/), defines it as "coders and decoders."
  
  However, newer material does not seem to be consistent. One of the Wikipedia page's [sources](https://web.archive.org/web/20091212070305/https://www.microsoft.com/windows/windowsmedia/player/faq/codec.mspx) (at the time a page author retrieved it) alludes to both encoder-decoder and compression-decompression. [This book](https://rads.stackoverflow.com/amzn/click/0240805801) defines it as compression/decompression.
