Because more and more cineasts are using sound recorders not speci-
fically designed for cinema, which means with no integrated timeco-
de, Aaton needed to modify its OriginCplus: now, OriginCplus is
able to serve as a SMPTE generator, which you can connect to any
sound recorder.
But OriginCplus may be too big and too powerful for such an usage.
So Aaton decided to build 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 can work conti-
nuously for 150 hours with just a standard 9V battery. Its timecode
informations (time and date) can be initialized with any SMPTE
generator such as OriginCplus.
To choose the SMPTE frame rate 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. The selected frame rate LED will
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.
8.7 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
a camera assistant as part of his/her routine.
8.7.1 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 occasionaly
