Welcome to the forum Albert, very informative fist post. Until now I was not aware of this rotating disc and the technology behind it as well as its place in history. Thank you for explaining everything I am smarter for reading your post. I hope other others read and appreciate your knowledge.
Keep up the good work.
Hi!- My name is Albert and I have been invited over to this forum by my friend Wolfgang Mayer.

While watching his incredible home cinema with all the latest technology some days ago, we thought it would be interesting to think back to how it all started in the 1920s.

So many things we take for granted today were the result of much headache, suffering and heartburn by the intrepid inventors who dedicated their lives to the idea of “seeing by wireless” or “radiovision” as the early experiments were called.
I am by no means a historian of television, but I love  to build things. So I started to research the early days with the idea to follow in the footsteps of the pioneers. I will try to let you follow this adventure.

Early television was a mechanical system. Before you laugh: Today’s sophisticated high end video projectors are full of mechanical parts. The creation of color images  with a black and white DMD device makes use of the idea of the color wheel, projecting the base colors in sequence. The ultra miniaturized DMD device is itself a mechanical system for switching single pixels.

It all started in 1883 when a young German student named PAUL NIPKOW sat in his little flat in Berlin around Christmas time and longed to see his family and parents back in Pomerania, where he came from. A train ticket was too expensive for him, and so he sat down and conceived a method to transmit images on a telegraph line.

He came up with the idea of  a fast-rotating disc with a series of holes punched into it. These holes were arranged in a spiral shape. A small window of the disc would be the scanning area. One hole in the disc traverses this window. As it exits the other side, the next hole moves across, but one hole diameter further to the inside of the disc. This way a scanning motion is imparted. the idea was so good it shaped the research and development of TV up until the 1930s when the first purely electronic tv systems started to emerge.

Young Nipkow patented his system as “electrical telescope” in 1883. But his invention came too early: Crucial parts of the system did not yet exist.  There had to be a way to capture the light across the Nipkow disc, and to amplify the very small currents created by the incoming beam of light . The photoelectric cell using selenium as the light sensitive element was still a very new invention, and in 1883 there was no way to amplify its signal. The patent proposes a clever controllable light source but at the time thiscould not be realized. So  Nipkow never made a dime from his invention.

Indeed Christie flew the pair of projectors that was used in the grading suite around the world. First to a demo at IBC 2016.Then a full length screening at NYC Film Festival (world premier) a screening in London, one in Singapore?, and I believe one in China, Hong Kong or Shanghai, I don't remember what I heared.
I got the feedback from some VIP about how this movie was shot and you are right I was wrong see here what he mail me:

"It was shot with two Sony F65 cameras.  These cameras have 8k horizontal resolution, but this does not translate into 8k picture resolution.  Rather it makes very good 4k resolution with oversampling.  The production was graded and released on a limited basis at 4K 120fps, the UHD BD is 4K 60p, one of the few titles available at this frame rate.
The best distance not to realise the pixels or the z-axis misleveled tiles is 12.5 feet. Fantastic image there.

Also do note that this set could be looking at a sunset without it being reflected or affected by the amount of light, so perfect for oceanfront movie watching is you do have the 12.5 feet /3.8 Metres.
Nope it was shot in 120. A 60P was created from that. I asked him if 120 was not limiting. Not really, but he would like to use 240 if and when available, I was suggesting 1200;-).
IMAX Continues To Invest In Young Filmmakers With Kick-Off Of Second Annual Student-Made Documentary Challenge
Company Awards a Total of $25,000 in Grants to High School Film Programs in Ongoing Campaign

NEW YORK, Nov. 17, 2017 /PRNewswire/ -- IMAX Corp. (NYSE: IMAX) today awarded $5,000 grants each to five U.S. high school film programs as part of its broader effort to educate students about key environmental and societal issues impacting the world and to inspire them to become advocates for change through filmmaking. Each student film program has been challenged to create inspiring documentaries to further IMAX's commitment to drive awareness of the global issues outlined in the United Nations' Sustainable Development Goals (SDGs).

The grants are being awarded for the school's participation in IMAX In Focus, a multi-faceted philanthropic program unveiled by IMAX last year to benefit the student film programs and help the next generation of filmmakers develop their creative abilities and use the power of film to drive positive change.

This year's participants for the 2017-18 school year, listed below, encompass a diverse cross-section of American high school students geographically, demographically and economically:

Cedar Crest High School; Lebanon, Penn.
Digital Arts & Cinema Technology High School; Brooklyn, N.Y.
A collaboration of The Marvelwood School in Kent, Conn., and Stamford Academy in Stamford, Conn.
Henry J. Kaiser High School; Honolulu
The Kinkaid School; Houston
Launched in October 2016, In Focus arose from IMAX's unique private-public partnership with UN Environment, the UN's agency that oversees environmental issues, which seeks to educate audiences about key societal and environmental issues impacting the planet.

Each school will create an eight-minute documentary and related social media content on one of the UN's 17 SDGs, which range from eradicating poverty and promoting gender equality to ensuring universal access to clean water and modern energy.

To ensure that a robust library of student-created content is available for global audiences, IMAX has chosen to address three new goals:

Zero Hunger, the collective endeavor to end hunger, ensure access to safe food supplies, improve nutrition, and promote sustainable agriculture.
Good Health and Well-Being, efforts to promote healthy lifestyles and overall well-being for all – regardless of age or domicile.
Sustainable Cities and Communities, the quest to make cities and other population centers inclusive, safe, resilient and sustainable.
"We are honored to work with another group of talented and deserving student filmmakers to help them unlock their creative abilities and see, first-hand, the power that the big screen can have in promoting positive change," said IMAX CEO Rich Gelfond. "We're proud to continue and expand the In Focus program, and fulfill IMAX's commitment to empowering the next generation of filmmakers."

Since starting the program last year, IMAX has worked with the All-American High School Film Festival to identify exemplary schools, with IMAX ultimately selecting the final five schools to participate in the In Focus program.

"Our partnership with IMAX proves that the industry is invested in the next generation of talented filmmakers," said All American High School Film Festival Executive Director Tom Oliva. "This unparalleled opportunity offers students real-world education, a chance to create content with purpose and a platform to share their unique perspective with the world."

In June, IMAX released five thought-provoking documentaries made by the 2016 inaugural class of the In Focus program. The students explored issues ranging from poor air quality in D.C. and water pollution in the Everglades to the declining honeybee population and angst in some U.S. cities over dwindling sources of drinking water.

The young filmmakers deployed an array of film techniques, including creatively interspersing interviews with officials from the EPA, the National Parks Service, the NOAA, the Coastal Watershed Institute, and state legislators. The full library is available on the IMAX website.

Ang Lee use 2 Sony F65 in a 3D Rick for the movie.
This Camera can shot in 8K but I am not 100% sure they can do 8K together with 120P.
8K 3D 120 Frame was told to me from one of the Studio Guy that should know it.
Anyway as I like to know it I have write a Mail to one that should know it for sure.
Also possible that the shot in 8K 3D at 60 P per eye and made from this content a 120P Version.
Ah, that was not what Ang Lee, and his head of technology, told us. But I am pleased to hear that they chose the highest spatial resolution available.
