OPERATION
The 4025 permits three different methods of updating the bi-phase based
numbers with the barcode data. The KKODE LED on the front panel,
shows each time a valid Barcode number is read.
Select NEVER to disable automatic data updates from the KeyKode
reader. The 4025 will use the bi-phase exclusively to update the edge
numbers. The front panel KKODE entry mode may be used to manually
enter edge numbers from non-KeyKoded stock. This may also be helpful
when transferring stock where a different film edge number (e.g. ACMAID
number) than the latent edge number must be used.
When the 4025 is in the Ink number mode, you can only select KKJAM
NEVER. To select one of the other KKJ modes you must first take the 4025
out of the Ink number mode by entering a manufacturer's code other than I.
See section 0.
Select ONCE to accept KeyKode numbers once, when the telecine is at
stable play speed (the 4025 LOCK LED will be On), and the bi-phase
based numbers disagree with the barcode numbers. After this the 4025
will use the bi-phase to update the edge numbers. This mode is useful for
transferring stock which has undesired breaks in the keykode numbering.
Select PLAY to accept KeyKode numbers only when the telecine is at
stable play speed (the 4025 LOCK LED will be On), and the bi-phase
based numbers disagree with the barcode numbers.
updating is done from the bi-phase. This mode is useful when transferring
uncut camera negative rolls.
Select ALWAYS to accept KeyKode data immediately when the telecine is
at stable play speed (the 4025 LOCK LED will be On), and the bi-phase
based numbers disagree with the barcode numbers. In shuttle speeds the
edge numbers will be updated after a pre-settable error window between
bi-phase counts and barcode numbers is detected. (See section 3.7.2 for
information on how to set the error window.) This is necessary to track the
discontinuous edge numbers that would be encountered when searching
select take rolls in shuttle. This value shows the amount of error in film
frames that the 4025 will allow, (in shuttle modes), between the bi-phase
based numbers and the barcode numbers. When this window value is
exceeded, the barcode numbers will approximately update the bi-phase
based numbers. The bi-phase based numbers will be exactly updated the
next time the telecine achieves locked play speed. The default value for
the window is 30 frames.
In the three KK JAM modes the bi-phase based numbers take priority and
will be updated only when they disagree with the barcode numbers.
