A list of the decisions that describe a series of edits. EDLs can be producedduring an off-line session and passed to the on-line suite to control the conforming ofthe final edit. In order to work across a range of equipment there are some widely adoptedstandards such as CMX 3400 and 3600. News journalists working with integrated newsproduction systems, such as Quantel’s generationQ news systems, can effectively createEDLs at their desktops.EDLs have been frozen in time and not kept pace with the continued development of postproduction. They do not carry information on DVEs, color correction, layering, keying etc.,orcarry otherdata about ownership, rights, etc.The development of AAF has filled these gaps.See also: AAF, Conform, OMFIEffects (digital film)Digital effects processes have replaced the traditional film optical effects, and provide a lotmore toward the completion of the project. Initially this was a separate digital operationaside from the mainstream photochemical work, but now, with DI becoming popular, it worksalongside the digital workflow.Digital ‘optical’ film effects can retain their full image quality irrespective of the numberof effects layers used, provided that the images remain uncompressed. The results cangenerally be seen immediately making the process interactive and able to quickly refinethe result. All this can be seen in context with the rest of the movie, making for bettercontinuity and less need of final grades.79
