This is a presentation that I gave in 2003, I really enjoyed it :-)...........
I’d
like to start this by mis-quoting Henry Kissinger
He
originally made the comment about politicians
“90%
of the people talking about HD give the honest 10% a bad name”
More
evasions, obfuscations and downright lies are told about HD than there are ever
uttered in Westminster!
I’m
interested in making quality pictures
Pictures
that influence the viewer, either to buy something (my ads) or feel something (my drama)
I
expect to use a wide range of tools to do this
I
may use colour effects, extreme lenses, contrast or gamma effects
I
might use blue or green screen
I
may well use variable speeds
The
common factor in whatever I shoot is an attempt to produce the best and
most appropriate image I can for that project
A
few examples: - (run tape)
They
were all dubbed off Standard Definition PAL DigiBeta except for SchoolDisco
which came off DVCam
So
why did I shoot them on film rather than digitally?
We
shot the Lego one was shot on super-35 and post produced at 2K
This
was because there was a lot of keying and compositing of pictures that the full
bandwidth 4:4:4 uncompressed image made possible, well, made invisible
There
was also some varispeed
The
Sharps was super-35 again and is a mixture of Standard Definition, 1K and 2K as
appropriate to the shot
One
of the shots is made up of 34 layers!
Every
shot, hell every frame, is manipulated in one way or another.
All
the walking shots of the model are at 29fps
We
did this because we tested every speed from 25 to 32 and found that she looked
best at 29
And
yes! There is a huge difference between 28 and 29 or 29 and 30!
I
included SchoolDisco.com because it was shot on 16mm
The
total cost of the camera hire, stock and processing was less than an HD kit
would have cost to hire!
So
there’s a good reason to use film J
Hey!
Show me any other HD camera this size! (Hold up A-Minima)
Why
film rather than HD for keying and post manipulation of the image?
Well,
the most widely available HD camera, the F900, records compressed 3:1:1
In
plain English, they throw away 25% of the Black and White information
and 75%!
Yes!
75% of the colour information!
And
then the little that’s left they compress 4.4 times!!
How
anyone can describe that as High Definition is beyond me!
Of
course it’s totally unusable for any quality post or FX work
And
before anyone says Attack of the Clones look at issue 90 page 98 of Cinefex
magazine, you tell me what camera that is, it’s not an F900
Now
there are alternatives to this;
You
can take the 4:4:4 uncompressed route as launched originally by Thomson with
the Viper and soon to be available from others
Of
course if you want to go the Sony route with the F950 and HDCam SR you’ll have
to wait at least 18 months
Or
Dalsa, and you’ll have to wait?????
How
long?
So
why don’t I like this route?
Full
bandwidth 2K uncompressed pictures!
What
can’t I like?
Well
actually I do like it; it’s just there have been a few practical problems
using it for the last year
Problems
that have now been addressed so I expect to see more productions using this approach
What were the problems?
Well,
as the data rate is so high, there is no tape format that can cope with
it
There
still isn’t,
In
18 months or so you should be able to get a 2:1 compressed 4:4:4 tape recorder
from Sony (HDCam SR), and that’s an acceptable level of compression
But,
that’s a long long way away even if they hit delivery schedules
So,
you have to record to disk
That isn’t a problem in itself
It’s
just that the Disk system that the Viper was launched with had a control unit the
size of a Hammond organ!
It
wasn’t practical in the field
Oh
I’ve used it on location
But
I’ve also flown Aeroflot!
Neither of which I’m in a
hurry to repeat!
The
post work flow wasn’t sorted last year either
You
get all this data on disk and what do you do with it?
Keep
all the disks until you do your online?
They
charge a hefty daily rental for those disk arrays!
Or
do you dump it all to disk at your favourite post house
You
think they aren’t going to charge you for extended use of huge amounts
of disk space?!
Anyway
as I said earlier, all this is working itself out now
There are now a number of hard disk recording systems that are easy to use and have all kinds of back-up options
By
“now” I mean either available now or “real soon now”
It’s
all coming but you’re going to be a pioneer if you do it this year.
I
do however love the pictures out of the Viper
These
are Viper pictures running in the background
And
once they get the fixes to the disk problems out into the rental market I’ll be
happy to use it.
As
for the other 4:4:4 cameras coming, well, they’re at least 18 months from
delivery so we can afford to ignore them and wait and see if anything leapfrogs
them!
And
it will! Maybe something with variable speeds, time lapse, upgradeable
CCDs,
PL mount film lenses, colour V/F, uncompressed disk recording on board, a
really solid aluminium body J
Of
course one of the biggest problems with any HD camera is a ViewFinder
that’s Black and White and half the definition, if you’re lucky, of the
picture you’re shooting.
Brings
back memories of being a TV camera operator a long long time ago
Director
screaming into the talkback “stay on the blue, stay on the blue”
My
reply of “and precisely which shade of grey is blue?” didn’t go down too well
Again
this is being sorted, but right now your world is 1” high low resolution
Black & White if you shoot HD
I
love the optical V/F for the Thomson, colour pictures at a higher definition
than you’re recording, no batteries required to see a picture, being able to
see things before they come into shot and accepting standard PL mount lenses
Now
there’s an idea J
Again,
I’m waiting for it to get into rental houses
So
basically what I’m saying is that HD is coming
It will be really good
But
it’s not here yet
As
a replacement for Betacam now?
Maybe
As
a replacement for film today?
Forget
it
Oh
and when you hear of series shooting on HD just ask yourself
“Would
they have shot on HD if they got the same level of discount on film cameras and
stock?”
You
know the answer to that
When
people compare HD formats or HD with film they generally don’t do an
all-inclusive comparison
They
pick on one aspect that may be better in isolation and ignore all the other factors
I
can do all kinds of sums to produce whatever kind of result I want
I
can make cars, houses & clothes much cheaper
I
can make more cars fit on the roads; more houses fit on the land, and make more
clothes out of the same amount of cloth
It’s
easy!
I
just have to make everything for people who are 4 feet tall!
It’s
nonsense! I know its nonsense, you know its nonsense
But
I can do the sums and prove that we can all save money
And
that brings us back neatly to where we started
Evasions,
obfuscations and downright lies |
