Versioning

In today’s multimedia world there is much demand for many version of a finished production. This business has ballooned. Historically versioning involved making copies from the edited and graded master to various videotape formats and, via a standards converter, to other video standards (e.g. NTSC to PAL). Now technical variations involve many more formats being supplied, including Web, mobile, HD and SD TV, DVD and cinema, as well as a variety of display systems including LED, LCD, Plasma and digital cinema. Aside from the technical needs, other requirements such as commercial, language and religious influences are among the many factors that can be causes for more yet versions.

Versioning is big business, as the number of versions can run to many tens and involve much more than simply making copies of the master. For example, work may involve re-grading to suit different viewing conditions, re-insertion of text or images to suit different regions or countries, pricing (for commercials) adding or removing shots or scenes for censoring, etc. Generally, for this to be done efficiently and effectively requires nonlinear editing in an uncommitted environment; where original footage and all the post processes that produced the master are available for recall and allow direct access to further adjustments, to re-make the result in a short time.
