4015
OPERATION
Evertz 4015 users note: The 4025's PERF numbering scheme has been
changed from the 4015 so that it conforms to the industry standard head to
tails orientation. The on screen graphic display in the Head offset learning
procedure accurately shows the KeyKode perf orientation so as to avoid
confusion.
SCAN
On Rank Cintel flying spot scanners, the SCAN value shows
how much the film is moving in the gate due to the effect of
Scantrack. When the telecine is first put into the PLAY mode,
the SCAN value should be approximately 00. When Scantrack
is enabled on your Rank Telecine, the SCAN value will change
gradually, with expected values of less than ±19.
On CCD scanners such as BTS telecines, this value should be
relatively constant and should be in the 15 to 18 range when in
the locked PLAY condition.
On all telecines, if the SCAN number exceeds ±19, an error in
the bi-phase based numbers is likely. This may be due to a
telecine with excessive Scantrack settings, or to improper
centering of the film when it is loaded onto the telecine. (See
section 3.10.8).
ERR
Indicates the whole frame error between the bi-phase based
edge numbers, and the barcode numbers being read. If the
installation is correct, the ERR value will be 00.
When the KKODE JAM mode is set to OFF, the error display
will continually show the difference between the bi-phase based
numbers and the corrected KeyKode numbers. If the KeyKode
number of the reference frame is manually entered, the error
display can be used to compare the accuracy of the bi-phase,
the keykode, or the head offsets.
When the KKODE JAM mode is set to ONCE, the error should
be 00 when the telecine is in Play, and the film has continuous
edge numbers. It will be non-zero after a splice is encountered.
A KJ indicator will appear at the right of the status line should
the bi-phase based numbers be updated with a different
barcode value.
When the KKODE JAM mode is set to PLAY, the error should
be 00 when the telecine is in Play, and the film has continuous
edge numbers. It will be non-zero momentarily when a splice is
encountered. A KJ will appear at the right of the status line
when the bi-phase based numbers are updated with a different
barcode value. When the telecine is in shuttle, non-zero ERR
values are normal.
