ded to built the GMT1, a mini SMPTE generator also designed to
provide a timecode track for any sound recorder. The GMT1 is
smaller than the OriginCplus, and it can work continuously for 150
hours with just a standard 9V battery. Its timecode informations (ti-
me and date) can be initialized with any SMPTE generator as with
OriginCplus.
To choose the timcode frequency you need (according to the speed
of your camera), remove the battery cover and turn the small white
cross, beside the 9V battery, with a screwdriver. You can choose bet-
ween 24, 25, 29.97 and 30 fps. To each choosen frequency corres-
pond one LED, which flash every second.
You can also use the GMT1 as an OriginCplus supplier: if one day,
by mistake, you have forgotten to take your OriginCplus with you,
then use the GMT1 to initialize timecode in your camera. The
GMT1, with no timecode initialized inside, is still able to generate a
SMPTE code, starting at 1h 00mn 00s.
7.7 THE CAMERA ASSISTANT'S DUTIES
Although timecode-related practices on the set are very straightforward
and uncomplicated, there are a few duties which should be handled by
the camera assistant as part of his / her routine.
7.7.1 Checking the Diodes
In order to inspect and clean the gate between magazine rolls, the
camera must be set to test position. Not only will test position rota-
te the shutter 180°, but the seven timecode LEDs in the gate will
illuminate in a three/four sequence. Use this pattern to occasionally
check that all diodes are operational and evenly illuminated. As part
of the normal gate cleaning procedure, clean this area with a Q-tip
and lens cleaning fluid to assure that no dust particles cover the
LED array.
The seven diodes will illuminate in test position whether or not ti-
mecode is running in the camera.
