On January 8, 2014, the Chinese media visited the Sony Pictures Entertainment Group in Los Angeles. Mr. Chris Cookson, President of Sony Pictures Entertainment Group, personally received and accompanied the visit and explained in detail. Mr. Cookson first showed the Chinese media a piece of the re-repaired 4K "Lawrence of Arabia", which contrasted the difference between the previous FullHD version and the 4K version on the stage.
Sony TV Group's colleagues in the TV series studio of the Sony 4K studio also showed the media guests how the original film film was digitalized in the data/scanning center of the underground layer, turning the analog signal into a digital signal (each movie) The original scan data is about 20-30TB, but it is said that the raw data volume of a 4K version of a giant can reach 1 PB!) for storage. The raw data signals are then transmitted to a dedicated small studio where professional fixers perform computer repairs on old movies on a frame-by-frame basis, including removing scratches, gray dots, and film itself from the original image. Physical damage caused by excessive or improper storage. After completing this step in each classic movie, Sony Pictures will re-create a film with the new digital version, and each movie will actually be "original master", "repair digital version" and "repair". The digital print film version "three forms are permanently saved. 
Mr. Cookson showed us the details of the 4K version of Arabian Lawrence. So what do you do with the new content? For Sony/MGM/Colom, they are now using 4K devices for a new film, whether it's a TV show or a movie. Of course, some directors insist on filming, but they still need to make 4K alphanumeric tapes for post-processing. The two studios we visited corresponded to the post-grading work of TV and film. The two studios are doing this kind of processing on a segment of 4K video and can see the effect right away! We clearly see that the RAW video material, which seems to be grayed out, has been adjusted in a few steps, and the contrast of the picture is increased with a golden tone. The producer uses the mouse to gently rub the face of the actor in the picture, and the brightness of the face is softly enhanced, and the stereoscopic effect is enhanced. What's even more amazing is that Sony's device can track a specific target (such as a face or sunglasses) in the picture according to the intention of the director or the editor, and firmly lock these specific areas and superimpose them in the active video picture. The right effects, all in real time! Obviously, the data processing capability of this system is incredible. I guess if we let our video editors see this kind of tall anti-sky equipment, they will definitely admire the tears and saliva! 
Superimposed image overlay before and after restoration and dynamic tracking of the screen 
Sony Pictures Group, the highest studio in the United States with up to 80 feet, has the largest studios in the United States. Most of these studios were built in the 1920s and 1930s, and the latest ones have been in existence for decades. They have witnessed the birth of classics in countless film history. What impressed the reporter is that there is a studio that claims to be the highest in the United States (more than 80 feet / 24 meters high). It used to be used as a filming studio for Spider-Man - built a four-story scene in it for Spider-Man. Among them, the flying dragonfly walked away. In addition, we also watched several shooting scenes of the US drama being broadcast. 
Mr. Cookson shows F55 professional 4K camera 
Mr. Cookson is in the hands of the latest F564K camera. Finally, Mr. Cookson led us into Sony's 4K digital studio. To our surprise, this studio is currently being used as a "classroom". When we entered, there was a group of videographers who were training on the latest 4K cameras, and behind the classroom there was a flagship model 4K camera such as F55/F65 as a teaching aid for the videographers to practice! Because such professional equipment is relatively expensive at present, a large number of Hollywood studios are renting 4K cameras to Sony, and Sony's studio can also provide rental services.
