High
Definition Fact Sheet 101

In an effort to aid production companies in making
wise educated decisions I have compiled a fact sheet to share the
truth and dispel some myths related to shooting High Definition
24P for Features and Television shows.
1) Shoot "23.98P" not "24P". Reason is you
will have difficulty downconverting and keeping sound in sync.
2) You don't need to offline in HD. Downconvert your footage to
DigiBeta or Beta SP and offline conventionally building a solid
EDL for online in HD.
3) Running time of HD Tape is 50 minutes @ 23.98 even though the
box will say 40 minutes (40 & 22 are available for field).
4) Average Cost of 1 HD Tape is $60.00 comes in case of 10.
5) Record the Master Sound on the HD camera tape in addition to
external recording devices (which should be running at 29.97 NDF).
6) Editing of dissolves, CGI, slow motion effects and titling
can all be done in the final HD Online session to create Final
HD Master. Then perform a Digital Color correction and "Film
out" or downconvert only the final show.
7) Shooting this way will save money by skipping Timing and Syncing
of dailies. This step is replaced with Downconverting.
8) HD Camera Packages will generally be more expensive to rent
than Film packages. Savings is in HD Tape vs. Rolls of Film purchase,
Processing, and Transfer. 1 HD tape = 5,000 ft of film run time.
9) Transfer from HD to film only your final edited show. This
step may cost around $60K for an entire feature. Not needed for
Commercials or TV. 10) Money Savings is in the Production medium
and Post, not in Personnel.
MYTH: You need less Crew to shoot HD.
FACT: The same number of crew in every department is necessary
to do the level of quality you expect. Only the Camera Department
has a loss of the Loader but the necessary gain of an HD Engineer
or "DIT" Digital Imaging Technician at a pay rate between "A" Camera
Operator and the DP.
MYTH: You need fewer lights to shoot HD.
FACT: I generally rate the HD Camera at 320 ASA for best performance
and I need just as much light as if I was shooting 320 ASA Film.
The same number and type of lights as in film.
For the Directors of Photography
1) HD exposes like color reversal (Slide film rather than negative).
2) HD has less latitude than Neg film. I call it 4 Under and 1.5
Over.
3) HD has much more bottom end in the blacks than top end in the
highlights, better to under expose rather than over expose.
4) You can get in essence Timed dailies in Camera which I have
found gives you more range than had you done nothing to the image. "Best
way to get to a good image is to start with one".
5) You can do a Digital color correction session after the picture
is locked then again after it gets "Filmed out" transferred
to Negative before it gets printed. Take every opportunity given.
6) HD is Tungsten base so ND and Color correction filters are
built into the camera and are ND.6, ND1.2, ND1.8, also an 85B+81B.
7) Electronic Shutter set to ON @ 1/48th is equal
to a 180' shutter. Shutter OFF increases blur in motion equal
to 24FPS @ 1/24th.
8) Like any new Film stock Test it to determine how your lighting
style looks with this medium if adjustments should be made.
9) Insure your 1st AC's and operators know how to properly set
the Back Focus or your images will be soft. Use proper Back Focus
chart.
10) Shoot Record run Timecode even if you do multiple cameras.
Cameras do not need to match TC for post to sync it up. If you
do shoot Free run Timecode you need 10 seconds of preroll before
Action is called.
11) Slow Motion is possible with HD that will match look of 60
FPS in Film by shooting 59.97 interlace then converting back to
23.98 with slow-mo in Post.
Sound Department
1) Record Master sound on the HD Camera this will create a permanent
synced source of CD quality sound for Downconverts and Offline.
Also always record sound separately in addition to on Camera.
2) Be aware that to hear the sound coming from the HD Deck that
you need a 5 pin XLR for discrete Ch-1 and Ch-2 return.
3) Whatever you choose to record on Nagra, DAT, DA88 or DEVA,
use 29.97 NDF (Non Drop Frame) because 23.98 is a NDF speed.
4) Use of a Timecode slate is helpful with TC being YOURS not
camera's TC. In addition have 2nd AC's Clap the sticks as always.
5) Also very helpful is feeding your TC into an available channel
of Audio on the Camera with an SB2 from Deneke. It's wireless and
provides a permanent source of sync for the external sound recording
device.

The fact is the script and style of show will dictate whether
it should be shot on Film or HD. HD is cheaper on the front end
because of tape cost and more expensive on the back end during
Film Out. But for TV the savings will be most noticeable and many
shows are now taking advantage of it.
You must weigh the options and make the best decision for your
show. Shows with lots of VFX, tight budgets and schedules are good
candidates as well as direct to DVD movies. I hope this helps shed
some light on High Definition Acquisition. Feel free to contact
me if you have any specific questions.

Besides being a Master
Director of Photography, Sean
Fairburn is a national hero. He's been the only
US Marine combat director and cinematographer positioned
on the front line of the Iraqi War. Using a Sony's CineAlta
F-900 HD camera provided by Panavision,
Fairburn was able to obtain incredibly clear and realistic
footage that provides an inside look into war and offers
a valuable historical archive. Sean's master works have been
featured on countless US and International publications.
