Status of 4K video production

8

• 4K is not yet done much.• Hollywood uses 4K already but not all. (Off line

editing)• 4K broadcast has been announced in Brazil,

Korea, Japan etc. Targeting the World Cup.• Test live broadcast of 4K soccer game has been

done in Japan in order to confirm the feasibility.• 4K test has been done in Europe, EBU etc.• Medical use is under testing in Japan, also in

USA. • Video conference system needs ultra-high-

resolution.


4K Camera overview

Many available Still camera evolved to 4K movie / Broadcast HD

camera evolved to 4K Most demand is cinema use Record the RAW signal and transfer to editing

system. Smooth data transfer to the non-linear editing, is very important.

Live 4K camera is not a main stream yet. Max size of real-time monitoring is still HD.

4K M/E (Mixer/Effect, Keyer) is not available yet

4K live production is not handy Decompose one 4K signal into 4 HDTV lines

and process them when real-time is required There's few real-time 4K digital processing

system. (eg. "Pablo" by Quantel, color correction)


Non-linear editing

17

4K mainstream is non-linear editing production. Off line editing on PC and rendering then transfer to recorder or burn DVD

Most of the non-linear editing soft can handle 4K

Adobe Premiere Pro, Apple Final Cut Pro, Avid Media Composer, Sony Vegas Pro

Editing procedure is advanced because of cinema use （ eg. Red one ＋ Premier Pro ）

Many have DVD and Blu-Ray authoring function

Summary of 4K video production

25

・ Off-line production is established

・ Cinema production is matured in Hollywood

・ Live production is not yet. Switcher is needed.

・ Up-conversion of 2K to 4K is used

・ Use of 4K other than video production is not yet done. → Ultra-CG

Status of 8K video production

29

• 8K real-time production is available compared to 4K. The reason is NHK promoting it

• Public viewing of London OlympicThree live ８ K cameras, switched on the site, transfer un-compressed signal to studio in BBC via optical fiber, recorded in BBC and encode in H.265 and transmit to Japan and US.

• 8K non-linear editing systems in Japan (Sapporo, BUG)

• Event use in NHK Studio Park, real-time 8K production

・ System for both off-line and on-line is developed

・ Small amount of production experience

・ No real-time up-conversion from 4K

・ Video production only, no other application→ Ultra-CG

4K Game

4K Game has huge impact

Normally, 4K （ 2K ） game is not so many due to the production cost

However, it is still very good when present PC game (for HD) in 4K system

Developing "serious game" is also the key

We have the 4K game development environment. Don't miss the high potential.


Globe project

• Digitize the Globe in 18 century in Uppsala University

• Requires ultra high-resolution texture. Globe is about 70cm diameter but still letters are so tiny.

• Interactive exhibition is capable by using 3D game method such as anotaion, comparison with Google Maps, etc.

Interactive 3D object in the 4K Virtual Museum


Digital Art

• Digital art exhibition• Computer art is resolution-

free• 4K/8K as the art material
