Offline (editing)A decision-making process using low-cost equipment to produce an EDL or a rough cutwhich can then be conformed or referred to in a high quality online suite – so reducingdecision-making time in the more expensive online environment. Most offline suitesenable shot selection and the defining of basic transitions such as cuts and dissolveswhich are carried by EDLs. It is only with the arrival of AAF that there has been an openstandard for transporting a much wider range of decisions, including DVE, color corrections,as well as other metadata, between systems from different manufacturers.See also: AAFOMFIOpen Media Framework Interchange is an open standard developed by Avid, for postproduction interchange of digital media among applications and across platforms.It describes a file format and supports video, audio, graphics, animation and effectsas well as comprehensive edit decision information.

This is the simplest, quickest and cheapest way to print all the filmand the results are typically used formaking rushes, dailies, etc. These are often subsequentlytelecined and recorded to videotape as a reference for the offline decision-making process.See also: Best lightOnline (editing)Production of the complete, final edit performed at full program quality – the buck stops here!Being higher quality than offline editing, time costs more but the difference has narrowedas the cost of equipment has come down. Preparation in an offline suite will help save timeand money in the online. To produce the finished edit, online has to include a wide rangeof tools, offer flexibility to try ideas and accommodate late changes, and to work fast tomaintain the creative flow and to handle pressured situations.Open Systems Interconnect (OSI)The OSI Basic Reference Model describes a general structure for communications,defined by the ISO, which comprises seven layers and forms a framework for the coordinationof current and future standards – but not defining the standards themselves.Website: www.iso.ch136
