5.2 QuadCam with SmartSync DV
QuadCam will produce accurate results even
with manually trimmed video material, but
SmartSync DV technology makes working with
up to four cameras even easier and more versa-
tile. SmartSync DV provides:
• Automatic synchronisation of video recordings
from up to four DV cameras. In particular, vide-
os of events gain enormous impact and profes-
sionalism when several cameras with different
perspectives are used. SmartSync DV ensures
that sound and picture remain synchronised,
so that you can concentrate on something
more important - the subject of your film.
• The possibility of changing tapes in the “in-
sert” cameras, interrupting individual recor-
dings briefly or of continuing the recording
from a camera switched off inadvertently. Only
the “background” recording has to be conti-
nuous. SmartSync will find the right starting
point automatically for the “insert” scenes.
5.2.1 Calibrating cameras with SmartSync DV
Only a little preparation is required to use
SmartSync DV.
• Set the clocks of the camcorders as close as
possible to the current date and time. However,
slight differences of several minutes are unim-
portant. Then check that the cameras are retai-
ning the date and time after being switched off.
If not, replace the clock batteries.
• Run QuadCam from the “Edit/Special” menu
option and check the box after “SmartSync
DV” on the right. Then click on “Measure ca-
meras”.
• Select the camera to be used as the “Back-
ground” camera” for the uninterrupted “back-
ground” recording and the cameras to be used
as “Insert 1”, “Insert 2” or “Insert 3”. Insert
suitably-labelled video tapes into the cameras
and also mark the cameras appropriately, to
prevent confusion.
• Now connect the “Background” camera to the
Casablanca by DV cable. Switch the camera
to Record (“Record-Pause”), but do not start
actual recording yet.
• Click on the “Background” button and then the
“Measure” button. The date and time from the
camera will be transferred to the Casablanca
and displayed under “Time of camera”.
• Carry out the same procedure with the “In-
sert” cameras., i.e. first select the button for
the camera (“Insert 1/2/3”) and then click on
“Measure”.
• Confirm the results of calibration with “OK”
and exit from the SmartSync DV menu.
5.2.2 Preparing the recordings
Multi-camera recording should take place as
soon as possible after calibration (see Appendix
A). Locate the cameras as desired and start re-
cording in the sequence “Background - Insert 1
- Insert 2 - Insert 3”.
Important notes:
• The “background” camera must run conti-
nuously throughout the entire recording peri-
od, so select video tapes with sufficient playing
time or use “Long play” mode on the camera,
if long tapes are not available.
• Recordings by the “Insert” cameras can be in-
terrupted. For example, if the “Insert 1” camera
was set to “Pause”, QuadCam will simply dis-
play black material during subsequent ”live”
video editing.
• If the cameras were not calibrated before
recording, they can be calibrated immediately
afterwards. However, under no circumstances
should hours or days pass between recording
and calibration, as increasing deviations in the
camera clocks will lead to a loss of synchroni-
sation during QuadCam editing.
