Exporting Audio Clip Information to an EDL
Some audio post-production software can import Edit Decision Lists (EDLs) in the same
way as video editing applications. Importing an EDL creates audio clips (or regions) in
the audio application’s timeline, which you can then use to recapture your audio from
original source tapes. This is similar to a video online edit session, in which all clips are
recaptured at the highest quality possible. Since the engineers are recapturing all of
the audio directly from the source tapes using workstations with dedicated high-end
audio hardware, you can be assured of the highest-possible quality.
EDLs can only store information for up to four audio channels, and the clips must have
been originally captured using timecode. If some of your audio doesn’t have timecode
(for example, if you imported a track from a CD), you must first transfer your music and
sound effects to a video or audio format with timecode and then edit the timecoded
clips into your sequence. If your program has more than four audio tracks, you need to
export multiple EDLs and have them collated by your audio editor.
For detailed information on exporting EDLs, see Volume IV, Chapter 10, “Importing and
Exporting EDLs.”
OMF Files Have a 2-Gigabyte Limit
OMF files that you create cannot be larger than 2 gigabytes. In most cases, this
should not present a problem because 2 gigabytes will accommodate approximately
7 hours of mono audio media (depending on the bit depth and sample rate of your
audio). If your sequence exceeds this limit, you will see a warning message before
exporting begins.
