OPTIONAL SOFTWARE
4.1.2
Setting Up The 4025TR To Operate In 3 Perf Mode
When the 3 perf option is enabled, a new film type is added to the FILM
TYPE menu item.
When the 35mm 3 perf film type is selected there is additional information
regarding whether a frame belongs to foot 1, foot 2, foot 3 that is encoded
into the VITC. In order to accomplish this you must set the GEN ASSIGN
to one of the 3-line modes. If you use one of the 1-line or 2-line modes the
information about whether a frame belongs to foot 1, foot 2 or foot 3 is not
encoded in the VITC.
Use the Film Tab of the Configuration screen to set the film type to 35mm 3
Perf.
4.1.3
3 Perf Indicators
The KeyKode and Ink Number VCG windows and front panel displays have
a special indicator between the prefix and the footage that indicates which
foot of the 3 foot sequence the film frame belongs to. This is important
because two feet have 21 frames and the third foot has 22 frames. On the
VCG, the indicator is a horizontal bar that is at the top for the first foot, in
the centre for the second foot and at the bottom for the third (long) foot. On
the front panel the indicator is an
center for the second foot and a horizontal bar at the bottom for the third
(long). The example below shows the three indicators for both the VCG
and front panel displays.
