So I have a gig coming up and need to do 2 things that are
out of my immediate area of expertise.
I know how I would approach this in film but in HDTV?
Here is the deal...
I believe we will shoot with the 900 Cinealta.
I need to sync to a monitor that will be the star of the shot.
I am worried that will it may appear to be in sync, what I
don't want is to have for example Frame X captured on the
video camera but the monitor in the scene will display the
one field from the previous frame and the field from the next
frame. (Frame Y with the upper field plus Frame Z with the
lower field) Does that make sense? I would be a single field
out of sync. This is a Composite heavy project that I will
shoot 30 Progressive. No room for imperfection.
Do I need to and how do I gen lock the camera to the source.
My next concern is a shot of a woman’s face. I wants
to be blown out with a glowing silky white complexion. The
director wants to see only blue eyes in a field of creamy
white skin. We have all seen this look. I know how I would
do this in film, as I am sure we all do, but what about HD
Video. My fear is that once blown out all detail will be gone.
I wont be able to follow this through the Post chain of custody
so I am looking for any suggestions anyone might have.
Thank You in Advance Gentlemen (persons)

Given what you are trying to do I would suggest to invest
in an on-set engineer to ensure that it gets done right the
A few points/questions :
Are you shooting an HD monitor or SD?
You say "30 Progressive". You probably mean 29.97
PsF. If you are shooting an HD monitor, make sure that the
material it is displaying is shot and produced at 29.97PsF.
Is this a locked-off shot or will there be any motion? In
theory, if you are shooting PsF and the monitor is displaying
59.94i it should work. In practice I would be concerned about
a timing issue causing problems.
Genlock is an absolute must. In the "old days" we
would genlock the film camera to the video source. I used
to work for a company called Video Image/VIFX that had a division
that specialized in this very thing. Anyhow, in your case,
if both camera and playback are the same standard you would
genlock both to the same reference. Not difficult at all.
If you are going to shoot an SD monitor your choices are narrower
and the potential issues go greater. You should not shoot
PsF with an interlaced display. You can only get away with
this if the material on screen is devoid of significant motion.
If it isn't you are bound to capture inter-field motion. A
lot of this is tempered by the size of the video image on
screen. If it is going to fill the HD frame you may have a
The alternative is to use an LCD-based display to take advantage
of the slower response time. When we started to use LCD's
at VIFX a number of issues went away. Today, you can walk
into any consumer electronics store in the US and choose from
among a couple dozen good LCD-based TV's. You might want to
use one of them for your shoot. This is not necessary if the
playback material will be HD as you can use a standard Sony
HD monitor genlocked to the same reference as the camera,
as I mentioned above.
Again, find an engineer who understands the issues involved
and it will be a very easy (and successful) shoot. The production
(and post) of the material to be shown on the monitor is just
as important as everything else.
Test, test, test. Ask the rental house to help you setup a
test. There's nothing like going on-set knowing what will
work and what will not.
For the look of your actor I think you need a combination
of approaches. And they start where you would if you were
shooting on film.
Get as close as you can to the look you want with lighting
If the wrong person is chosen for this shot, you are at an
instant disadvantage. The next step is a combination of filters
and/or nets, camera detail/enhancement settings and a controlled
use of the F900 knee function. Get a good VC, which it sounds
like you need for the other part of your challenge anyway.
He can turn off the camera's Auto DCC and then adjust the
knee for the right amount of near clipping and white crushing
that will give the blown out creamy skin tone you're after.
This may also be a rare opportunity to actually use the skin
detail function of the 900.
I think the look you're describing isn't so much a blown out/no
detail look but a look where the face is represented in a
very narrow range of values.
As Martin said, get yourself a good engineer explain the look
you want and test...
