When you hear the word IMAX, one filmmaker almost inevitably comes to mind, Christopher Nolan.
For close to two decades, Nolan has pushed IMAX further than anyone else,
championing it as the premium format for capturing blockbuster spectacles.
With the upcoming release of The Odyssey, that relationship deepens once again,
driven by the arrival of the first newly designed IMAX camera in decades, since the late 90s.
On paper, it's another technical leap forward, which unlocks not only hardware changes,
but more importantly, an entirely new way of using this epic film format.
In this video, we'll break down how the camera body has changed,
why it matters for the future of large format filmmaking, and how an innovation designed to
silence a camera may quietly unlock the most significant creative shift IMAX has ever seen.
This new camera is named the Kili, in honor of IMAX Chief Quality Officers David and Patricia Kili,
whose decades-long commitment to technical excellence,
exhibition integrity and uncompromising quality standards help define IMAX
as a cinematic format rather than just a screen size.
When we talk about camera upgrades, image quality is usually the first thing that comes to mind,
but with IMAX, the footage itself is already defined by the format,
Massive 15 Perforation 65mm Film. Because of that, changes to the camera body don't
meaningfully alter image quality, as the look is dictated entirely by the Kodak film stock running
through it. Although they do mention that film exposure on the new camera should be a bit more
even and stable. Almost all of the upgrades are either technical or ergonomic in nature,
focused not on improving the image, but on expanding the way the IMAX camera is used
and how easy it is to do so. At first glance, it's easy to see that IMAX cameras are incredibly large,
cumbersome and heavy, as I'm sure Hoitavan Hoitama and his lower back can both vouch for.
With all the camera accessories added and a 1000ft roll of film loaded,
the camera weighs around 25kg or 55 pounds. The new Kili camera body, although the form
may look largely the same, tries to make this weight more bearable by using lighter weight
carbon fibre. It's made out of mostly of composite materials, carbon fibre, honeycomb sandwich
panels, the same stuff that your Formula 1 is made out of, and titanium, the same stuff that
jet fighters are actually made out of. Before we continue, I want to take a moment to thank

an exact live preview of what the sensor is capturing, film cameras don't have a native
way to show the recorded image. They expose light onto film, which then has to be sent to a lab and
processed before it can be viewed. To bridge that gap, film cameras rely on a video tap,
a system that offers an approximation of the final image. On the new IMAX camera, this takes
the form of a small 4k UHD sensor built into the optical viewfinder, sending a signal out through
an SDI port. External monitors or wireless transmitters can then be connected, giving
the crew a clean detailed live image of what the camera is seeing. There is attachments to the
camera that can now take the 4k UHD tap out of the viewfinder and go into the cloud, so people
can see stuff either on set or on their iPads instantaneously and at a much higher quality
than ever before. Film cameras never had that capability. Visual frame line guides can now be
overlaid on the SDI output as well, helping crews accurately compose for different or multiple aspect
ratios and exhibition formats, such as the native 1.43 to 1 or 1.90 to 1 that will be seen in IMAX
cinemas, as well as a widescreen 2.40 to 1 frame that will be displayed in regular cinemas or on
streaming services. This 4k feed can also be recorded and reviewed as dailies, allowing filmmakers to
watch back takes without waiting for the film to be developed and scanned at the lab. The Kili update
also introduces metadata capture, meaning camera information can be displayed and passed along for
both on-set monitoring and editorial workflows, bringing IMAX film production closer to the
experience of modern digital cinema cameras. This is a major leap forward from the original 1990s
era IMAX cameras whose low resolution video taps could only suggest basic framing, offering little
clarity when it came to focus, exposure or colour. On Oppenheimer and other previous Nolan IMAX
productions, cinematographer Hoyt van Hoytema often refrained from using Steadicam or cranes with
remote heads for just this reason. The eyepiece was far superior to the old video tap system.
With a 4k video tap this issue is now fixed. I love looking through the viewfinder, that's one
of the reasons why we wouldn't go necessarily on Steadicam or on like a stabilised hab because
the moment you do that you prohibit yourself to look through the viewfinder, you know you're
reliant on a video system. When you shoot a format like IMAX it's very important that you
keep checking through a viewfinder because the video quality is very, it's very low fi and it's
very low res. The Kili IMAX also features a newly designed optical viewfinder developed with
Panavision. When shooting on film a bright eyepiece is essential and this new finder delivers a
noticeably clearer, more comfortable viewing experience. Behind the scenes images reveal two
configurations, a shorter eyepiece for handheld with the operators close to the camera body
and an extended eyepiece intended for studio setups with the cameras mounted on a dolly
and the cinematographers positioned on a seat with the camera lower and further away.
Prototype images of the camera body show what appear to be three SDI video ports,
two 2-pin power ports for use with accessories like focus motors or transmitters and a dedicated
power input for a block battery, signalling a far more flexible and power-ready hardware design.
The redesign also comes with an updated digital menu and a 5-inch display. Rather than a minimal,
purely mechanical readout like the older models, the display presents clear production relevant
information at a glance. Along the top of the menu battery voltage is shown which lets ACs
know when a battery change is needed. In the top right the frame rate is clearly displayed,
in this case 24fps. The menu has a comprehensive film management readout.
Local appears to indicate how much film remains in the magazine yet to be shot,
shown here as 980 feet out of a 1000 foot roll. Forward likely displays how much film has already
been exposed from that roll, in this case 20 feet, which is probably the leader of unusable film
which is exposed when loaded into the magazine. The system also tracks the total length in feet
shot across the entire project. Perhaps the most useful addition is the estimated remaining
runtime of the current magazine before the unexposed film runs out and the camera needs
to be reloaded with a new one. Here it sits at 2 minutes 58 seconds, roughly the recording time per
1000 foot roll. For camera assistants this is a super useful feature, allowing them to anticipate
reloads with precision rather than instinct. But the most significant breakthrough doesn't
come from the image at all, it comes from sound. Historically the greatest limitation of IMAX
cameras has been their noise. The deafening whir of 15 perf 65mm film racing through the camera body
made recording usable sync dialogue on location nearly impossible. As a result, IMAX was
traditionally reserved for action, spectacle or wide shots where dialogue could be avoided or
replaced later. The new Kili IMAX reportedly reduces camera noise by roughly 30%. It is also
compatible with a purpose-built blimp system, a large acoustic housing that dramatically dampens
the sound of the camera movement. Together these changes allow the notoriously loud IMAX camera to
capture clean synchronized dialogue on set. This is why the Odyssey will become the first ever
feature shot entirely on 15 perf IMAX, including all dialogue scenes. The trade-off however is an
ergonomic one. Once blimped the camera becomes enormous, closer to the hulking technicolor
cameras of early cinema. Practical only on a dolly and exceptionally difficult to transport
to remote exterior locations of which the Odyssey had many. The Kili IMAX doesn't reinvent the
format's image, it removes the barriers around how that image can be captured. By addressing weight,
usability, monitoring and most critically sound, IMAX has quietly transformed a specialized
spectacle camera into a far more flexible storytelling tool for making A-tier blockbusters.
With that now being possible to use them for capturing everything from the largest of set
pieces to capturing intimate moments of dialogue. Thank you for your ongoing support and a special
shout out to the dedicated patrons who help make this channel possible.
Otherwise until next time, thanks for watching and goodbye.
