The term 'editing' is often used in two slightly different ways. Sometimes it is referred to as the process of selecting and re-recording just the good footage, eliminating the bad. Sometimes the term is used for only a part of the post-production process, including titling, effects, etc. For the purposes of our study, we shall consider the second.
Editing is only a minor part of post-production because post-production does not stop with editing the video but also includes promotion, distribution, etc.
A number of considerations go into making edit decisions during the post-production phase. However, some of the reasons why we would want to edit the footage available after shooting are to
Reasons why we would want to edit or Need for Editing:
Join a series of disjointed shots to create meaningful scenes and sequences and, in turn, a film in totality
Omit portions of the footage that we would consider as unwanted, irrelevant, or even distracting and to Increase or decrease the duration of a Programme/film
Shift the audience's interest from one aspect of a scene to another
Emphasize or conceal information
Reveal information in stages
Deliberately change the significance of an action
Rushes mostly coming from tapes and once a programme is completed, it is dumped back on tape-a master tape. The master tape is the one on which the final programme is recorded.
If we use a tapeless video camera (ones that use disks for video storage instead of tapes/chips), our footage will be in the form of files. edited in a computer to edit the footage and dump the completed film on a tape or a CD/DVD.
