By George Avgerakis
My brother, a seasoned video producer himself, once
noticed that I was shooting an industrial video with
two cameras, which not unusual, except that one camera,
the JVC
BR-DY90U cost $20,000 and had a $10,000 Fujinon
A19X8.7 BRRM-28 lens, while the other camera cost
$450, including the lens. The second camera was an
Optura20
from Canon.
"Why are you using a consumer camera on a professional
shoot?" My brother asked, "You can't match
the two in an edit, right?"
"Well," I said, "There are several
reasons. The first is that the Optura
20 comes to my set for free from the assistant
cameraman, who just bought it as a family-home camera."

And so began about an hour discussion that I will extract here
for both your professional and avocational benefit.
What Is the Optura
20?
Before we can discuss the mixing of consumer and professional
cameras in a professional environment, let's first examine the
parameters of a good, consumer camera - and I would consider the
Canon Optura
20 quite good.
Working from the source light, through the lens to the CCD chips
and finally to the tape deck, let me give you a brief run down
of what's required for a consumer camera to make the grade. First,
the lens has to offer at least an f2 physical low light exposure
capability (The Optura's is 1.8) and, for me, an old timer, it
has to offer physical focusing capability. The Optura offers both
manual and auto focus, with a 16x power zoom. Many consumer cameras
offer only electronic auto focusing, which makes professional
grade photography near impossible.
Next, the camera has to offer a variable shutter (the Optura
goes to 1/8,000 of a second) which is essential in obtaining quality
exterior action shots and shots of computer screens (remember,
we're using this for industrial videos, right - lots of computer
screens).
Moving to the CCD chip, I'd like to see more than one, but you
rarely find a consumer camcorder with three chips - this is almost
a definition of prosumer if not professional - so the CCD should
produce at least a half a megabyte of video per frame (720 pixels
X 480 pixels = 345,600). Keep in mind that many of the pixels
available to a camcorder will not become part of the picture area
- those that do are counted as the "effective pixels."
For instance the Optura20 has 1.33 million pixels on its ¼"
CCD, but only 690,000 are effective.
The light sensitivity of the CCD is also important. Don't be
fooled by gimmicks that boost the light sensitivity at the expense
of quality, such as a gain booster. The Optura20 has a recommended
illumination of 100 lux. Using the camera's "Night Program"
you can get a picture at .5 lux, but it isn't the kind of picture
you'd use outside a police station.
From the CCD, the video signal passes through a digital signal
processor and then to both the tape, the viewfinder and possibly
an LCD screen. Consumer cameras are famous for providing color
viewfinders and LCD screens. Consumers are like dogs. They're
dumb enough to chase their own tails.
Color viewfinders and LCD screens, even the nice .33" viewfinder
and 3.5" LCD on the Optura
20 are nearly useless when trying to check focus or contrast
- two of the most important aspects of videography. When it comes
to checking color, they aren't much better, because you really
need at least a 13" broadcast quality monitor to check color
in the field - and then you have to have a pretty good eye. So
my suggestion is to patch the video output of the Optura
20 to a real monitor, capable of switching from color to B&W.
The last consideration when using a consumer camera for professional
work is the microphone on the camera. Don't use it. Buy a small
box called a CleanBox by ART (ARSC) for $49 which converts a professional
microphone's output, coming from a 3-pin XLR cable, into the non-professional
2-connector "mini" jack on the camera. This box will
have a dial to adjust the gain and a jack to monitor the sound
from the microphone and perhaps from the camera. Now you can place
that microphone out where the sound is originating (not on the
camera) and, exploiting the Optura
20's, 16-bit sound (48kHz on 2 channels) or 12-bit sound (32
kHz on 4 channels), obtain really professional results.
Uses of a Consumer Camcorder in Professional Applications
While a consumer camera lacks many of the tools of a professional
camera, one of the things that a professional camera lacks is
the ability to take snapshots. True, you can freeze a frame from
a pro camera, but not a frame with 1,200 pixels square. The Optura
20 can knock out snaps that exceed HD frame size, and, when
so many videographers are using Adobe After Effects (ADAEPPSBW)
and eyeon's Digital Fusion (DPDFC), it's nice to have photos from
the field which can be scanned on the X-Y plane larger than one
frame's size.
So there's reason number one to have a camera like the Optura
20 on the set. Here are some more.
As I'm shooting with my high end JVC camera, I can have an assistant
shooting our crew at work, another angle of the interviewee, B-roll
footage that adds another perspective to principal photography,
or - home video footage of the clients having a great time on
the shoot.
Here's where my brother's big question comes into play, how do
you match this footage into a scene shot with a camera costing
20 times more?
First - and this is an arguable point - under optimum shooting
conditions, in a wide shot, and with perfect focus, I don't have
any trouble matching a shot from a consumer camcorder with a professional
camcorder.
My brother would then challenge me with, "But then how can
you justify spending that kind of money on a professional camcorder?"
The answer is that the professional camcorder will produce the
same optimal results in a shooting conditions which are not optimal,
it will do far superior close-ups, the footage will not lose quality
when dubbed, the tape is more robust, the digital density of the
recorded image is several magnitudes greater, etc., etc.
So keep in mind, you can match only under optimum conditions.
But why bother to match at all?
How about those MTV style documentaries where the main, color
camera, is switched with a grainy, black & white camera, or
the lesser quality image is inset, smaller than full screen, as
second image - again that After Effects influence. If you take
a consumer camera shot and reduce it to a quarter screen, you
can easily use the result as a "mortise" shot within
a DigiBeta sequence.
Imagine a limited-budget documentary about a really beautiful
vacation resort. We can't afford two days on location, but we
need both beauty shots and interviews to make the client happy.
I send Robbie Anderson, my premium-priced camera dude, out to
shoot all the really beautiful scenery; splashing waterfalls,
crystal clear lagoons, native gals doing the wakka kula. Me? I
go with the crack assistant cameraman, Joe Anthony and do customer
interviews with the Optura
20.
Later, in the editing room, we shrink the interviews down to
quarter screen size, add a tropical flower border and lay it over
the Robbie's beauty shots which are running full screen - maybe
even 16 x 9.
Of course, you have to get the client to buy into this strategy
from the beginning. You don't want her to ask for a full screen
shot of the interview and then complain when the shot doesn't
intercut with the wakka kula.
Now that we have the matching issue safely to bed, let's think
of creative ways to employ the consumer camcorder.
In the land of video camera design, it is a well known fact that
size has some relation to cost. This may seem odd. In an era when
doctors are shoving high resolution cameras into your small intestine,
why should a broadcast camera weigh 20 pounds and lay on your
shoulder like a led parrot? The reason is marketing. Professional
cameramen (yes, men) want to demonstrate impressive iron when
they earn the big bucks.
Show up at a White House press event with a hand-held camera
and see how far down the kill tunnel you get. Show up for a $5,000-a-day
shoot at any Fortune 100 company with a XL1-S and it's be the
last $5,000-a-day shoot you ever get. Maybe things are a-changin'
you say, indicating the Time Magazine photos of embedded journalists
carrying the Sony DSR-PD150 while dodging insurgent bullets. Good
point. But if a guy is going to dodge bullets to get my footage,
he can use whatever camera he wants.
Which is how you can really decide how far to carry the Optura
20. It's really small, runs on one battery all day, isn't
so expensive you wouldn't sacrifice it for a career-making shot,
and it produces a pretty fine picture - considering.
Considering what? Considering if you couldn't get the shot any
other way. For instance, what if the client wanted you to shoot
the inside of a sewer pipe? Don't laugh. I just answered a bid
request to do just that for a construction company in Westchester
County. "Not with my DY-90W, I won't. But Mikey'll go."
Mikey is my Optura
20.
Here's another fun thing to try. Give the camera to your client
and let them shoot stuff for you as a lark. This is also great
to try on camera scouting days. You do scout locations don't you?
This is when the director and cameraman go out and look over the
scenes to be shot a day or so before the actual shoot. It's one
of those upper class benefits that better clients can afford.
For scouting, I take the Optura and shoot every angle we might
shoot in the real production. Then I hand it to the client and
ask the client to visualize for herself, what she'd like to see
- and I ask her to speak while shooting, so I have a running commentary
on the tape. Nice, eh? Makes it harder to misinterpret a client's
desires.
Then there's the very last suggestion anyone ever needs for a
small, inexpensive video camera. This one comes from the late
Stanley Kubrick, who wanted a really cool point-of-view shot when
Malcolm McDowell, in "A Clockwork Orange," is thrown
out of a second story window.
Kubrick had an old Newman Sinclair 35mm movie camera (the kind,
perhaps even the very model, that Flaherty used to shoot "Nanook
of the North." Sacrificing it's antique value, Kubrick packed
it in a styrene box, cut a hole for the lens, and threw it (six
times) out the second story window attempting to get the camera
to land right on the lens face. The camera (but not the lens)
actually survived the event (read about this at http://www.visual-memory.co.uk/amk/doc/0070.html).
Now, I'm not suggesting you take the Optura
20 to the top of the Empire State Building (from the top of
which, by the way, there is no clear drop to the street), but
by 2009, the Freedom Tower will have one spectacular drop and
you should, by then - well, let's say there's gotta be an Optura
30.
