Edit decision list

An adapt accommodation account or EDL acclimated in the post-production action of blur alteration and video editing. The account contains an ordered account of reel and timecode abstracts apery area anniversary video blow can be acquired in adjustment to accommodate the final cut.

EDLs are created by offline alteration systems, or can be cardboard abstracts complete by duke such as attempt logging. These days, beeline video alteration systems accept been abolished by non beeline alteration (NLE) systems which can achievement EDLs electronically to acquiesce autoconform on an online alteration arrangement - the amusement of an edited programme from the aboriginal sources (usually video tapes) and the alteration decisions in the EDL.

They are additionally generally acclimated in the agenda video alteration world, so rather than apropos to reels they can accredit to sequences of images stored on disk.

Some formats, such as CMX3600, can represent simple alteration decisions only. Both XML and the Avant-garde Authoring Format (AAF) are almost avant-garde book formats that can accommodate adult EDLs.

B-roll

Linear alteration systems cannot deliquesce amid clips on the aforementioned video tape. Hence, one of these clips will charge to be dubbed assimilate a fresh video tape. EDLs baptize these occurrences by appearance such dissolves' antecedent reels as B-roll of "b-reels". For example, the EDL will change the 8th appearance of the reel name to the letter B.

However, sometimes editors will (confusingly) use the letter B to baptize timecode break on a video tape. If there is burst timecode on a video tape, there will be two (or more) instances of a accurate timecode on the video tape. When re-capturing, it can be cryptic as to which timecode is the appropriate one. The letter B may announce that the appropriate timecode is from the additional set of timecode on the video tape.

EDL incompatibilities and potential problems

EDL formats such as CMX, GVG, Sony, Final Cut Pro, and Avid are agnate but can alter in baby (but important) ways. Particular absorption should be paid to reel allotment convention. On the Avid, reel names can be up to 32 characters, but user should be acquainted that these EDL's don't attach to online alteration apparatus ascendancy specifications. These are acclimated by systems that accept adapted the import/export cipher to handle file-based workflows as band accretion formats wane. On FCP, in CMX3600 format, alone eight characters are allowed. Particular absorption should be paid appear b-reels. If the EDL handles dissolves to the aforementioned reel, reel names should be bound to 7 characters back the 8th appearance may be replaced.

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

Overall, EDLs are still frequently acclimated as some systems do not abutment added added able-bodied formats such as AAF and XML.

Systems known to support EDL to some extent

Avid Media Composer

Adobe Premiere Pro

Blender 1

Emacs 2

MediaCoder

Final Cut Pro (Support was alone with Final Cut Pro X.)

Any able alteration arrangement and abounding others abutment some anatomy of XML/EDL.

Systems supporting EDL playback, not just EDL cutting

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

Avidemux project files.
