OPTIONAL SOFTWARE
APERF is an internal register used in the ARRI timecode offset
calculations.
AERR is the whole frame error between the biphase based Film
timecode numbers, and the numbers being read from the Film
Ident system.
ASFERR is the partial frame error between the biphase based Film
timecode numbers, and the numbers being read from the Film
Ident system.
AJ1 Is an optional display that occurs when the biphase based
numbers re-jam to the numbers being read.

Setting the ARRI Reader head offset

The KRA16/35 KeyKode/ARRI timecode reader head contains both the
Timecode and Keykode sensors, and is mounted on the telecine several
frames before the film enters the gate.
4025TR that are used to compensate for the head offset. This could be
expressed as follows:
TC Offset = KK Head Offset + ARRI Offset
The KeyKode reader head offsets are also used to adjust the nominal
timecode head offset. As such, there are separate Keykode head offsets
maintained for each film gauge and transfer rate supported by the 4025TR.
(See section 3.5.4 for information on calibrating the KeyKode head offset).
We highly recommend using Telecine setup screen of KeyLog TRACKER™
to learn the KeyKode and ARRI time code offsets. See section 2.13.
The KeyKode head offset should be set before proceeding, as it is used for
both KeyKode and film timecode offset calculations.
