2.12. CONNECTING A FILM BARCODE READER
4015
INSTALLATION
If the Edge numbers are not correct, or do not match the picture
pulldown, check to see that you have properly compensated for
any delays in the video path from your telecine to the 4025.
(See section 3.5.5)
If the timecode numbers are not correct, check that you have
set the correct FILM RATE setting (See section 3.4.4)
In 24 FPS NTSC transfers, the pulldown of the reference frame
is not guaranteed unless you are using a device such as a
Time Logic Controller to control the telecine. This means that
the reference film frame may correspond to more than one
video frame, and that the exact timecode / edge code
numbering relationship is ambiguous except for A frame
pulldowns.
In 30 FPS NTSC or 25 FPS PAL transfers; see section 3.12.6
for a discussion of Field 1 dominant and Field 2 dominant
characteristics.
9. After you have made any adjustments, park the telecine with the
reference frame in the gate and repeat steps 5 through 8 until
you have satisfactory results.
With the introduction of machine readable edge numbers by Eastman
Kodak and other film stock manufacturers, (referred to as KeyKode
numbers), the edge number information can now be read by a bar code
reader, eliminating the tedium and human error, and providing an
absolutely accurate identification, entry and tracking of film edge numbers.
The 4025 Film Footage Encoder interfaces to reader systems from several
manufacturers.
consist of a bar code pickup head, and a decoder device. The pickup head
transforms the optical dark and light bar code into electronic signals and is
designed specifically to mount on the telecine feed roller just before the film
enters the gate. The decoder receives these electronic signals from the
pickup head, and sends the decoded KeyKode number via a serial link to
the Film Footage Encoder, for automatic placement into the time code.
2.12.1. Hardware Installation
A nine pin female 'D' connector (AUX I/O) is provided on the rear panel for
connection to an external KeyKode reader. Most of the KeyKode readers
use RS-232-C level signals to communicate with the 4025.
Evertz 4015 users note that this is NOT the same connector used to connect
the KeyKode readers to the 4015 Film Footage Encoder.
