EDL file extension - Edit Decision List file
What is edl file? How to open edl files?
File type specification:
The EDL file extension is associated with the Edit Decision List file format.
Edit Decision Lists (EDLs) are a means for describing the editing steps a video editing engine must perform in order to generate the desired output. EDLs can be created by hand, translated from another format, or by another application.
MediaWare's EDL format version 3.0.X is a CMX style EDL. 'CMX Style' is an industry term used to describe any reasonable derivation of the original EDL format that was specified by the CMX Corporation in the early 70s. The CMX EDL format was designed to work with early videotape editing controllers that were capable of performing basic edits between 'reels' or video tapes. The CMX EDL file format uses an ASCII (text) file, which makes it readable, and increases its portability. Edit lines contain edit number, reel id, edit mode and type information together with in and out points specified using SMPTE timecode values.
MediaWare's MPEG editing technology is file and stream based. Its EDL format 3.0.X modifies the original CMX EDL format to allow filenames rather than reel number to be specified. In the same manner as for CMX, MediaWare's EDL format uses SMPTE timecodes to specify edit in and out points since MPEG, like professional video tape, contains SMPTE timecodes recorded at regular intervals. In addition, MediaWare's format also supports others ways of specifying in and out points which are described later in this document.
