ARRI ALEXA 35 Body & PL Mount Set (LBUS) - Manual (Page 42)

Main Parameters 42
Regen Based on the timecode run mode, the camera determines the timecode
source automatically when set to Regen .
If the Run Mode is set to Free Run , the camera regenerates timecode
from the timecode connector. The timecode source must be connect-
ed to the camera permanently. Upon disconnection or loss of signal, the
camera continues counting on its own, but will indicate the missing sig-
nal. When the signal is reconnected, the camera uses the value of the
external signal again.
If Run Mode is set to
Rec Run , the camera regenerates timecode from
the last clip of the recording medium by continuing seamlessly from the
last active value.
Preset The camera uses its internal counter.
Jam Sync The camera samples the timecode from the timecode connector and si-
multaneously tunes its internal timecode clock to match the clock of the
timecode source. During this procedure, the timecode display on the
HOME screen, on the timecode menu screen as well as on the Status
Info is blinking. Jamming has finished when the timecode display stops
flashing, now the timecode source can be disconnected.
Info: Jam-sync is not available when Timecode Run Mode is set to Rec
Run.
Info: Due to the tuning mechanism, jamming the camera might take up
to 30 seconds and a timeout is issued if tuning could not be completed
after 60 seconds.
Setting the Timecode Manually
► Select HOME > TC > Options > Timecode .
to edit the timecode.
Info: Timecode can not be set manually when the timecode mode is set to either Regen or Jam
Sync .
Timecode Count Mode
The Count Mode sets the preference for how timecode is counted when using non-integer project rates
(29.97p, 59.94p).
► Select
HOME > TC > Options > Count Mode to set the count mode.
Following options are available:
Non-Dropframe Timecode increases with every frame without compensation, resulting in a 1,001 count for
1,000 frames.
Dropframe Timecode values are dropped with a defined pattern (frame counts 00 and 01 of every
minute, except every 10th minute) to re-adjust for the drift. A semicolon between timecode
seconds and frames indicates an active dropframe timecode.
Timecode Offset
You can apply an offset to LTC input signals to compensate for timecode offsets in external devices.
► Select
HOME > TC > Options > TC Offset .
► Adjust the timecode offset in the range of -20 to +20 frames.
