3.10.7 BCD or Binary Edge Number Encoding?

Use the Film tab of the Configuration screen to select the film encoding
format.
Film stock manufacturers traditionally have each had their own method of
numbering the film stock, some having 4, 5, 6 or 7 counting footage digits
with varying numbers of fixed alpha-numeric roll numbers, or prefix
numbers to the footage. Using normal BCD encoding, there is only room to
encode a maximum of 6 digits of film feet plus 2 digits of frames into the
user bits. By utilizing a compressed binary format, up to 7 digits of feet
plus frames can be encoded, along with the pulldown information, however,
special decoding routines in the time code readers such as the
Afterburner will be required to recover this information and display it as
decimal digits. If you are operating the 4025TR in one of the 3-line modes,
the encoding format is already specified.
Selection of the BCD or Binary encoding style is performed using the setup
menu displayed on the character generator.
