Edit decision list

visites-interactives Film and video terminology

An edit decision list or EDL is used in the post-production process of the film editing and video editing . The list contains an ordered list of real and timecode data Where Representing Each video clip can be Obtained in order to accordance the final cut.

EDLs are created by offline editing systems, or can be done by logging . These days, linear video editing systems-have-been superseded by non-linear editing (NLE) systems qui can output EDLs Electronically to allow autoconform is an online editing system – the recreation of an edited program from the original source (usually video tapes ) and the editing decisions in the EDL.

They are also often used in the digital video editing world, so they are referring to reels.

Some formats, such as CMX3600, can represent simple editing decisions only. Final Cut Pro XML , the Advanced Authoring Format (AAF), and AviSynth scripts are relatively advanced file formats that can contain sophisticated EDLs.

B-Roll

Linear editing systems can not dissolve between clips on the same video tape . Hence, one of these clips will need to be dubbed onto a new video tape. EDLs designate these instances by marking such dissolves’ source reels as B-roll of “b-reels”. For example, the EDL will change the name of the letter.

However, sometimes editors will (confusingly) use the letter to designate time code breaks on a video tape. If there is broken time on a video tape, there will be two (or more) instances of a particular time code on the video tape. When re-capturing, it can be ambiguous as to which timecode is the right one. The letter B may indicate that the right time is the second set of timecode on the video tape.

Incompatibilities and potential problems

EDL such as CMX, GVG, Sony, Final Cut Pro, and Avid are similar but can differ in small (but important) ways. Particular attention should be paid to reel naming convention. On the Avid, these names may be up to 32 characters, but they should be aware that these edits do not adhere to online editing machine control specifications. These are used by systems that have modified the import / export code to handle file-based workflows as tape acquisition formats. On FCP, in CMX3600 format, only eight characters are allowed. Particular attention should be paid towards b-reels. If the EDL handles dissolves to the same reel, reel names should be limited to 7 characters since the 8th character may be replaced.

EDLs can use either drop-frame (DF) or non-drop-frame timecode (NDF), running at 24fps (non-drop-frame only), 25fps (non-drop-frame only), and 30fps (drop-frame and non-drop- frame).

Overall, EDLs are more commonly used as more AAF and XML.

Systems known to support EDL to some extent

Almost Any professional editing system and many others Support Some form of XML / EDL saving / processing.

Some that make the list:

  • Avid Media Composer
  • Adobe Premiere Pro
  • Digital Vision Nucoda and Phoenix
  • Blackmagic Design DaVinci Resolve
  • The Foundry HIERO
  • Blender supports EDL in versions 2.4x and versions from 2.66
  • MediaCoder
  • Final Cut Pro
  • Fairlight Dream II and Xynergi Systems

EDL playback, not just EDL cutting

Probably most of the above, plus any professional editing system, plus

  • Avidemux project files.
  • Bs.player [1]
  • MPlayer (EDL specifies what to skip or only one source file for EDL; see also http://linuxgazette.net/178/brownss.html )
  • MPlayer2 (EDL specifies what to show from which file) [1]
  • mpv ( MPLs and MPlayer2) [2]
  • MythTV cut list
  • SageTV
  • SMPlayer Automatically Loading and Matching
  • VLC media player with xspf queues That Specify start and end times, or with movie editor happy
  • Kodi / XBMC
  • Zoom Player Max
  • mrViewer with real files, which are plain ASCII files.
