Uses
Audio track LTC recording
To record the exact TOD (Userbits inserted from Logger) of the ALL to an
audio track of the camera being used, thus allowing this timecode to used
in post production to sync sound and picture.
Note: Recording Audio track LTC can be done simultaneously to logging
Burst LTC
LTC can be recorded at the beginning of a take for 1 second, using the burst
LTC triggered by the camera start/stop info from the LANC or external TC
input. After this the Audio channel is free for audio recording ( 2 channel
audio with Timecode)
Logging using Aux. TC input .
Using an external Rec.Run. LTC to make a log against ALL internal TOD.
Internal timecode software filters and checks the LTC in signal and only
makes a log when the camera is in record. Spooling or shot playback
timecode does not trigger a log.
LANC INTERFACE
The ALL’s LANC interface can read the LANC signal of a Sony** camera
and the through output allows a zoom control to still be connected to the
camera via the ALL. The ALL takes its powering from the LANC socket,
Note:Available current at the camera LANC socket is about 70mA at 5
Volts. The ALL takes 50 mA. Leaving 20 mA for a zoom control, this is as
adequate for most zoom controls but can lead to malfunction if more
than 15mA is used.
Alternative powering is through the Lemo socket with 6 to16 Volts
voltage range.
** other manufacturers using the Sony LANC protocol (Canon) do not
adhere to the Sony protocol. Neither the message framerate nor
timecode values are ouputted correctly. The ALL can only read the
LANC from Sony cameras. Panasonic control M is only suitable for
remote zoom connection and does not output Rec.Run. timecode values
as does the Sony LANC.
LANC Signals read
Camera start stop
Rec.Run. Timecode
Any other available data that could be useful to log
TIMER
The ALL can be used to start and stop the camera at specific TODs
allowing remote start and stop, for example slow motion shots**.
