Two duplicate frames marked above the clip in the Timeline by the automatic Dupe Detection feature
Orange bars mark the first set of duplicate frames, green bars mark the second set, and so on.
You can use Dupe Detection while you edit to locate duplicate frames, and remove them as the
sequence evolves.
Activating Dupe Detection
n
You can change the handle size used by Dupe Detection in the Edit tab of the Timeline Settings
dialog box. For more information, see “Adjusting Handle Length in Dupe Detection” on
page 727.
c
Your Avid editing application might mark a special effect optical (such as a blowup) as a
duplicate frame. Double-check your sequence for this possibility before deleting frames.
To activate Dupe Detection:
t Click the Timeline Fast Menu button, and select Dupe Detection.
Dupe Detection occurs instantaneously and retroactively; if duplicate frames already exist in
your sequence, the colored bars appear immediately. As you edit, your Avid editing
application dynamically displays the duplicate frames.
Methods for Changing Handle Length in Dupe Detection
In 35mm film editing (using the single-strand method), one extra frame, known as the safety
frame, provides tabs for the negative cutter to use when cutting two segments of film together.
However, this frame is always lost during the negative conform.
