4. CINEGRID
• Production, transmission and viewing of soud and video
in ultra-high quality using high performance fiber optics
• 4K - 1 frame = 4 x HD: 4096 x 2160 pixels
• Uncompressed ca. 8 Gbits per second
• 5,5 TB for 1 ½ hours of film ~1200 DVD’s
And:
A worldwide community of
scientists, technicians and
audiovisual artists that invent
and shape a new
promissingmedium
7. 4K ASPECTS
KEY
• Immersive experience
• Collapse of distance
• Two or more way communication
PROMISES
• Potentially unlimited screensize
• Potentially unlimited storage
• Potentially unlimited bandwidth
• Potentially unlimited participants
SO WE CAN
• Reach and engage with a worldwide audience
• In previously undreamt of quality
11. 4K IN BUSINESS
In March 2009 AMC Theatres (4500 screens)
announced that it closed on a $315 million deal with
Sony to replace all of its movie projectors with 4K digital
projectors starting in the second quarter of 2009 and
completing in 2012.
WITHIN TWO YEARS UP TO 12.000 SCREENS
16. CINEGRID GOALS
• Feature Films (live action / animation)
• Educational Usage
• Scientific Visualization
• Extremely HQ Videoconferencing
• Reproduction of
Performances
• Gaming
• Television
17. EDUCATIONAL CHALLENGE
• 2010 4K Contest by SURFNet and Waag Society
• Goals: first educational applications of 4K content
• 12 entries
• 5 winners
• Prize:
– access to 4K production set
– technical & artistic assistance
– 5K in cash for out-of-pocket cost
• Target group: Higher Education Audiovisual Centers
18. WINNERS
• Larger than Live: Research into the impact of high
image quality on viewers
• Enhancing the safety of bike lanes, using 4K video
of people navigating an unknown terrain
• Teaching how to use Geographic Information
System (GIS) data, using the high resolution of the
4K screen
• Classroom based training with 4K-microscopy
imagery, using the 4K screen to make both details
and larger context of biological preparations visible
• Research into resolution, perception and
information overload, by filming a complicated
scene that puts high demands on the viewer
20. FIRST FINDINGS (LARGER THAN LIVE)
• The filmed 4K material was just about 25 minutes.
However, this lead to 1,5 TB of video material. As a
result, render and copy times soar and can amount to
nights and days;
• 4K cameras have a low dept-of-field. This can be
used for artistic purposes but can be a nuisance in
low light conditions;
• It is not possible to see the full resolution of the
recording on the set. Currently the 4K result can be
viewed after post-production only.
• COOKBOOK

21. FURTHER DIRECTIONS
• Medical applications, eg. by extending 4K cameras
with a catheter;
• Social research, eg. analyzing classroom situations
or studying the use of space and behavior;
• Capturing performance art, like theater and dance
from the perspective of the viewer;
• Scientific visualization where lots of data have to
be judged in parallel, eg. in climate studies, biology,
chemistry, physics and astronomy;
• Videoconferencing and collaboration, especially in
many-to-many settings.
22. CHALLENGES
• Expensive hardware requirements: cameras,
screens, computers, encoders, decoders and
projectors;
• Infrastructure for storing and editing is complex and
often inaccessible;
• Current lack of an experienced community of like-
minded but multidisciplinary practitioners;
• Currently there is no commercial way to use 4K in
real-time.
23. CINEGRID IN THE NETHERLANDS
• Testbed for viewing, production and transport of 4K
material
– Digital projection and sound of very high quality
– Editing and capture facilities
– Rendering & disk space
– Extremely high quality networks
• In the center of Amsterdam
• Experimental & business use
• International networks
• Maximum spin-off

This slide shows the number of pixels of candidates as UHDTV. The UHDTV(8k) has four times more pixels than HDTV, and the UHDTV(4K) has two times more than HDTV, horizontally and vertically. \n \nGenerally, the standard viewing distance of television is defined as the distance which an observer, who has 20/20 vision as visual acuity, is unable to perceive the pixels. For UHDTV, the standard viewing distance is 0.75 to 1.5 times of picture height. 0.75 value is for UHDTV(8K) system. 1.5 value is for UHDTV(4K) system. At this distance, an image on the screen can be viewed at a horizontal angle of about 100 to 60 degrees, which is much wider than that for HDTV. This means that, with UHDTV, we can see images on a much grander scale.\n

We staan aan de vooravond van een transformatie die de mediasector fundamenteel gaat veranderen;\nFilmproducenten en televisiemakers werken steeds meer samen in (virtuele) teams; \nDoor CineGrid ontstaan de mogelijkheden voor nieuwe formats en producten en worden nieuwe businessmodellen mogelijk; \nCineGrid brengt wetenschappelijke, economische & creatieve ontwikkeling en gebruik samen;\nLanden en regio’s die erin slagen om deze innovaties sneller om te zetten in mainstream media zullen daar economische vruchten van plukken.\nDoor verbindingen met universiteiten, hogescholen en marktpartijen worden de mediaprofessionals opgeleid met technologie die elders pas over een aantal jaar beschikbaar is. \n\nFrancic or Copola 1981 - looking at Elecronic Cinema\n

The winning entries all demonstrated the following qualities:\n•Need for a lot of detail in the image to make use of the high resolution;\n•Capturing moving images, the hallmark of video;\n•The currently used resolution clearly falls short of what is needed.\n\n
