OPERATION
the timecode output in one of the EDGE modes. (See section
3.10.1 for a discussion of how the film edge numbers are
encoded into the user bits.)
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 KKJAM 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. At other times 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.
exceeded, the barcode numbers will approximately update the
bi-phase based numbers. The bi-phase based numbers will be
