Appendix A

Digital cameras and SmartSync DV

In principle, any DV or Digital8 camera is com-

patible with QuadCam and SmartSync DV if it

fulls the requirements in Chapter 3.

Nevertheless, some tests should be carried out

before the rst serious event is lmed 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 signicantly 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

specic 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 nished lm. 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.
