Apple Final Cut Pro 7 - Manual (Page 998)

• Include Crossfade Transitions: Because some OMF importing tools do not handle cross
fade transitions correctly, and many sound editors prefer to create cross fades
themselves, you have the option to leave cross fades out when exporting your sequence
as an OMF file. When this checkbox is deselected, extra source media is substituted for
the duration of the cross fade being left out. How much extra source media is substituted
depends on whether the cross fade was edited before, on, or after the edit point. Extra
source media included as a result of this option is in addition to extra source media
added by the Handle Length option.
• Include Levels: Audio levels and keyframes are included in the exported OMF file. Even
if no audio level keyframes are set, the current level of each clip is exported.
• Include Pan: Pan settings and keyframes are included in the exported OMF file. Even if
no pan keyframes are set, the current pan setting of each clip is exported.
5 Choose a location and enter a name for the file.
6 When you’re ready to export, click Save.
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.
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 “Importing and Exporting EDLs.”
