The term cut bag can mean two different things. Literally, a cut bag is the manila/interoffice envelope used to contain a cut/sequence as well as the timing sheet and maybe associated drawings. This keeps everything together for transport within the studio. It is generally marked on the outside with the series name, episode number, and cut number and stamped with various markers. Some people sell ‘cut bags’ as the envelope and its contents (a full sequence of cels).
