Duplicate List and Double Usage Warnings
When editing digitally, it’s easy to include a clip or part of a clip more than once in the
edited program. When this happens, you either have to create a duplicate negative or
reedit the program to remove the duplicate usages, because the footage exists only once
on the original camera negative. But first you have to know where the duplicate usages
are, and that is the purpose of the duplicate list and double usage warnings.
Duplicate List
The duplicate list is what you give to your lab if you want the lab to pull specific shots
from your negative rolls and make duplicate negatives for you. It documents every shot
for which there is one or more duplicate usages.
Note: Content that is part of an optical is not counted as a duplicate usage. However,
placing a dissolve transition between two clips that have no other source footage available
between them (such as two clips that were originally one clip) results in a duplicate usage.
Double Usage Warnings
If you choose Warn from the Duplicates pop-up menu in the Export Film Lists dialog, a
warning message appears where duplicate usages occur in the cut list. The message tells
you exactly which frames have been used more than once and exactly where in your
editing project they are used. All of these messages also appear in a double usage warning
list.
Optical List
The optical list serves as a master list for transition, filter, and motion effects. If there is a
series of connected transition and motion effects, the optical list combines them and
describes them as a single optical. You give the optical list to the optical house to outline
how the effects shots are to be assembled.
Note: Titles, which are another kind of optical, use a second video track and are not part
of the optical list. You can export a separate cut list for the track that contains the titles.
See Using Effects, Filters, and Transitions for more information.
An optical list actually consists of up to four separate lists:
• Optical list: This list contains an entry for each cut list event that uses an optical effect.
Based on the type of optical effect, each entry links to one of the three effects lists
(described next) that are also included with the optical list. These effects lists include
the actual details of the optical effect.
• Transition effects list: This list contains an entry for each optical list entry that contains
a transition effect, such as a cross dissolve or wipe. See Transition Effects List for more
information.
• Filter effects list: This list contains an entry for each optical list entry that contains a filter
effect, such as a blur or color correction. See Filter Effects List for more information.
