You can automatically recreate a timeline
as it was edited during the offline editing stage of post-production
provided you have all the source footage that was used, and a CMX3600-formatted
EDL, ALE, or Cutlist file that describes how the source footage
is arranged in the timeline. The process of rebuilding the timeline
is called assembling.
When Lustre loads
an EDL, ALE, or Cutlist file, it builds the timeline based on the
following information:
- Source In/Source Out timecode or Record
In/Record Out timecode.
- Tape/reel name. If the Use Reel Name
button is enabled, Lustre verifies that the sources come from
the correct tape. The tape name is part of the file path, and is
always located one level above the resolution directory. For example,
if the source files are located in .../Scans/myclip/001/2058x1556/… ,
then the tape name is 001.
- Source table. The source table enables
the support of EDL reel names longer than eight characters.
- Dissolves. When Lustre finds a dissolve
in the EDL, ALE, or Cutlist file, it places a dissolve of the specified
duration at the appropriate transition.
- Speed changes. When a speed change is
encountered in an EDL, ALE, or Cutlist file, the speed of the appropriate
event is adjusted in the timeline using the Retime option.
To assemble an EDL, ALE,
or Cutlist file, the system matches shot timecode values to source
timecode in the EDL, ALE, or Cutlist file. Shot timecode values
can be interpreted using two methods:
- By reading the timecode from the DPX
file header. This method is intended for file formats (such as DPX
files) that can contain embedded timecode values in the file header.
- By converting the shot's filename into
timecode. The filename is established during the film scanning process.
The following table illustrates
how a filename is converted into timecode.
