Appendix A
Digital cameras and SmartSync DV
In principle, any DV or Digital8 camera is com-
patible with QuadCam and SmartSync DV if it
fulfils the requirements in Chapter 3.
Nevertheless, some tests should be carried out
before the first serious event is filmed to en-
sure that the cameras are fully compatible with
SmartSync DV technology and to check whether
the clock battery of the camera needs to be re-
placed.
• Set the camera clock as accurately as possible,
using either a radio-controlled clock or radio
time signal.
• Wait 24 hours, then check how far the camera
time deviates from the real time. If the devi-
ation exceeds two seconds, it is advisable to
change the clock battery (“button cell”). Please
consult your camera manual or dealer about
how to replace the clock battery.
• Some more recent models of camera no longer
have a clock battery. The clock takes its power
from the rechargeable camera battery (through
an internal “buffer”). The clock in such came-
ras can deviate significantly even a very short
time after disconnection of the rechargeable
battery. For this reason, the rechargeable batte-
ry should remain connected between calibrati-
on and recording.
• It is possible for a camera clock to be some-
what inaccurate. The greater the deviation in
the camera clock from real time, the closer the
time of calibration must be to the time of recor-
ding later. The cameras must therefore be cali-
brated using SmartSync DV very shortly before
the recordings or very shortly afterwards.
• After these tests, connect your camera to the
Casablanca with a DV cable and check whether
SmartSync DV can load the date and time cor-
rectly, as described in paragraph 5.2.1. Please
inform us if SmartSync DV fails to detect a
specific DV or Digital8 camera.
• Calibrate your cameras with SmartSync DV
as described in paragraph 5.2.1 and make a
test recording. For example, read a text to the
cameras or tap a pencil against a table. Then
edit this material with QuadCam, as described
in paragraph 5.2.3. Pay particular attention to
lip-sync when playing back the finished film. If
the picture and sound are already out of sync
at this stage, one of the cameras used may not
be compatible with SmartSync DV.
