Working with edit decision lists


An edit decision list (EDL) harkens back to the days when small hard drives limited the size of your video files, and slower processors meant you could not play full resolution video. To remedy this, Lesson 15, is a significant step up from EDL. AAF was created to be something along the lines of a "super-EDL." Its purpose is to foster more cross platform interoperability. In the case of the AAF that comes with Premiere Pro, it is compatible with a competing product, the Avid Xpress product line.


CMX is gone but its EDL lives on


There is no standard EDL format. Premiere Pro uses a format compatible with the CMX 3600, a switcher created by CMX Systems, a pioneer of production studio and broadcast-TV computer-controlled video editors. Formed as a joint venture by CBS and Memorex in 1971, CMX owned 90% of the broadcast video editing market by the mid-1980s, It discontinued operations in 1998. But its EDL remains the de facto standard to communicate edit decisions.

If you plan to use an EDL, you need to keep your project within some narrow guidelines:

  • EDLs work best with projects that contain no more than one video track, two stereo (or four mono) audio tracks, and no nested sequences.

  • Most standard transitions, frame holds, and clip speed changes work well in EDLs.

  • Premiere Pro 2.0 now supports a key track for titles or other content. That track has to be immediately above the video track selected for export.

  • You must capture and log all the source material with accurate timecodes.

  • The capture card must have a device control that uses timecode.

  • Videotapes must each have a unique reel number and be formatted with the timecode before you shoot the video to ensure there are no breaks in the timecode.

    To view the EDL options, select File > Export > Export to EDL:

  • EDL Title Specifies a title to appear in the first line of the EDL file.


Note

The title can be different than the file name. After clicking OK in the EDL Export Settings dialog box, you will have the opportunity to enter a file name.

  • Start Timecode Sets the starting timecode value for the first edit in the sequence.

  • Include Video Levels Includes video opacity level comments in the EDL.

  • Include Audio Levels Includes audio level comments in the EDL.

  • Audio Processing Specifies when audio processing should occur. Options are Audio Follows Video, Audio Separately and Audio At End.

  • Tracks to Export Specifies which tracks to export. The video track directly above the video track selected for export is designated as the key track.
