ABSTRACT:
A video processing system 1 comprises a video tape recorder 2 which serves as a bulk store for storing video clips, a video disc store for storing video data relating to one or more video clips from the recorder 2 and an image processor 6 for processing video data from the video store 7 to produce an edited video clip. Set-up data identifying video frame locations and defining the manner in which the processor 6 processes data from the video store 7 to produce the edited video clip is stored in an editing memory 12. During or after editing, data can be archived for future use. The system 1 further comprises a magneto-optical disc store 35 for storing the set-up data from the editing memory 12. For the purpose of archiving, the video tape and an associated magneto-optical disc are assigned a common archive identity. Each frame of data from the video disc store 7 used in an edit is stored only once on the video tape and set-up data for the edit is stored on the associated magneto-optical disc. This minimises the amount of data that needs to be saved in and retrieved from the archived tape.
