When the
Head offset learning is complete, verify the accuracy of the system by
performing the verification tests as outlined in section 2.13.6 of the 4025TR
manual. When examining the video tape, make sure that you check the
numbering for three consecutive feet of film, to ensure that the 4025TR is
properly identifying the short and long feet. The horizontal bar indicator on
the character inserter window will tell you what the foot type is for a given
film frame
The 4025TR MUST be configured to operate in the 35mm 8 perf film type
from the KeyLog TRACKER™ software. Once configured, the 4025TR can
continue to operate in the 35mm 8 perf film type while in Local mode, until
power is removed.
however the STATUS screen of the 4025TR will show 35mm 8 Perf.
When the 35mm 8 Perf option is enabled the system is capable of working
with film exposed in the 35mm 8 perf film format, (also known as
Vistavision). Most of the functions of the 4025TR operate the same as for
35mm 4 perf, except that the maximum film frame number is 07.

8 Perf Numbering

On 35 mm film, the KeyKode numbers change once per foot, or every 64
perforations. There is also a mid-foot KeyKode number which is indicated
by a smaller human readable number and a perf offset of 32. In the 8 perf
format there are 8 perfs per frame, giving 8 frames per foot or KeyKode
number.
