Dupe Detection
726
Example of a splice on a safety frame. Frames 1 and 3 are still usable, but frame 2 has been cut in the middle and
is lost.
In 16mm film editing (using the multiple-strand method), labs sometimes use the zero-frame
cutting method to avoid seeing each splice in a 35mm blowup print. In this method, the negative
is conformed along with the handles so that the cuts appear as soft frame handles rather than
jumps in the resulting 35mm blowup.
Different labs have different standards depending on the equipment used. Usually, a minimum of
four frame handles is needed.
Example of zero-frame cutting with multiple strands. The handles are shown in lighter gray.
Adding specific handle lengths to dupes (as they appear both in the sequence and in film lists)
has the following advantages:
• In 35mm single-strand conforming — Editors can better track duplicate frames and provide
the negative cutter with more than one safety frame to avoid losing specific frames.
• In 16mm multiple-strand conforming — For labs using the zero-frame cutting method,
editors can track the number of handles during editing according to the specific standards of
a particular lab.
