4.3 65mm OPTION
OPTIONAL SOFTWARE
The 4025TR MUST be configured to operate in the 65mm film types from the
KeyLog TRACKER™ software. Once configured, the 4025TR can continue to
operate in the configured film type while in Local mode, until power is
removed. The FILM TYPE menu will show EXTNDED TYPE, however the
STATUS screen of the 4025TR will show the configured film type.

65 mm Film Frame Formats
There are two types of KeyKode numbering in use on 65 mm film. In the
original format, the Key numbers change once 80 perforations. There is
also a mid-key KeyKode number which is indicated by a smaller human
readable number and a perf offset of 40 from the reference frame. The Film
types supported (5, 8, or 10 perfs per frame) for the 80 perf Keykode
repetition film stock are referred to as 65/80 in the KeyLog TRACKER™
software.
In the newer format, the Key numbers change once 120 perforations.
There are also intermediate KeyKode numbers that are indicated by
smaller human readable numbers and a perf offset of 40 and 80 from the
reference frame. The Film manufacturer number in the KeyKode allows the
4025TR to distinguish the 120 perf film stocks. The Film types supported
(5, 8, 10 or 15 perfs per frame) for the 120 perf KeyKode repetition film
stock are referred to as 65/120 in the KeyLog TRACKER™ software.
The chart below shows the film types supported when the 65mm Option is
enabled, and the maximum frame counts for each.
Film Stock Type
65 / 80 5 Perf
65 / 80 8 Perf

65 / 120 5 Perf
65 / 120 8 Perf
65 / 120 10 Perf
65 / 120 15 Perf
When the 65mm is enabled, most of the functions of the 4025TR operate
the same as for 35mm 4 perf, except that the maximum film frame numbers
shown above apply.
