OPERATION
footages of 4, 5, 6 or 7 digits may be used. Digits that are not used for
footage numbers are utilized for the prefix number. In addition, to the
prefix, footage and frames, three flag bits are encoded into the user bits
which contain the pulldown of the given field. EVERTZ style encoding
requires an Evertz Afterburner reader to read and display the data as
decimal digits.
(See section 3.4 for information about EVERTZ style
encoding.)

The newer barcoded film stocks use a consistent numbering system
consisting of a film manufacturer's letter, an emulsion letter, a six digit
prefix and a four digit key number. When using KeyKoded film stock, the
4025 should be set for the 4 DIG FT + FRM format.
3.10.8 Centering the 4025's Framing Reference
For the 4025 Film Footage Encoder to detect where the film frame
boundaries are (with respect to the bi-phase pulses and the barcode
numbers), it is necessary to properly calibrate the 4025's framing.
