ACMADE code aka "rubber numbers" aka "ink numbers" in the form of a 3 digit
prefix with limited alpha characters as a forth digit and then a 4 digit
footage count, printed every foot, e.g., 111A 1000.

Yes, but it also enables one to track sync.

Actually, once the workprint and mag are sync'd, they are then coded with
matching numbers. One way to code is to use the scene number as the prefix,
e.g., scene 22 codes as 022, then takes are combined into 1000 foot rolls
and the footage number starts ascend by multiples of 1000, e.g., first roll
of scene 22 would code as 022 1000, the second reel starting with 022 2000,

Poor (compared to colorists) film assistant and apprentice editors sync and
code all the dailies. Some assistants have developed their own electronic
database to deal with all the information - as a code book is after all
just a database on paper. We have also developed an electronic code book
for use by assistants transferring shows with us. Some of the information
tracked could be scene, take, lab roll, camera roll, daily roll, shoot
date, lights, ink number, key number, sound roll, notes.

Maybe, but it's lived every day by anyone working on a show that prints
film and mag. Sometimes to the tune of 20,000+ feet/day - now that's a
