Getting started with QuadCam
QuadCam combines up to four simultaneously-
recorded videos to make a film. QuadCam adds
freely-selectable inserts from a maximum of
three cameras into a “background” scene.
For such synchronised cutting, either a pre-
cisely-defined synchronisation point (“clapper
board”) must be present in the video material,
or the cameras must be connected to Casablan-
ca for “calibration” as close as possible to the
time of recording.
QuadCam consists of two programs: “Smart-
Sync DV” for calibrating the cameras and a cut-
ting program for editing the recordings.
Calibrating cameras with SmartSync DV imme-
diately before or after a recording makes work-
ing with QuadCam easier, but is not absolutely
necessary.
For example, if you have nothing to film at pres-
ent, you can edit existing “old” video material.
We actually recommend doing this before your
first experiments with QuadCam, so that you can
get to know the program.
5.1 QuadCam without SmartSync DV
This paragraph describes the use of QuadCam
without automatic synchronisation by Smart-
Sync DV. At least two video scenes recorded at
the same time are required for “live” video edit-
ing without SmartSync DV.
5.1.1 Preparing the recordings
Before making each QuadCam video recording,
both the video tapes and the cameras should be
clearly marked “Background” and “Insert 1/2/3”.
When planning, remember that QuadCam will
insert scenes from the “Insert” cameras into the
”background” during subsequent “live” video
editing. Your soundtrack will therefore come
from the “background” scene, whilst the “in-
sert” scenes are cut precisely to the soundtrack.
Accordingly, all the cameras used must make an
absolutely continuous recording of the whole
event. No camera may be switched to “Pause”
during a QuadCam recording and none of the
scenes may contain any interruptions.
Position the cameras, start recordings and set a
precisely-identifiable synchronisation point be-
fore actual recording begins. It must be possible
to locate this point to the exact frame in all the
recordings, like the well-known clapper board in
professional film productions. A flashgun is also
suitable, as the flash is recorded by all the cam-
eras in the room at exactly the same time, does
not usually cause any disturbance and can be
directed at any point in the room.
5.1.2 Preparations for “live” video editing
The simultaneously-recorded scenes are loaded
into the Casablanca Scene bin and then trimmed
so that they have a common starting point.
Trim the “IN” point of all the scenes involved to
the synchronisation point previously set, to the
exact frame. If you cannot find a unique visual
event in your recordings to use as a synchro-
nisation point, acoustic synchronisation using
the audio waveform display is possible in most
cases (only available with the Pro Pack on the
Casablanca Avio). In this case, trim the scene to
the beginning or end of an obvious sound, such
as something falling or a handclap.
