Converting 4K

For those of you who didn't believe it was possible to convert movies to 4k here's the proff !

We've recently invested in UltraHD Scanners being installed at 4K Studios. These scanners take a 35mm (we can do 16mm as well) film, and take multiple digitization of each frame of film at different light levels in Red, Green and Blue creating an HDR 4K image for frame of the film. At the same time, the audio track image from the film is scanned and put into a synchronized audio file. During scanning we run the film through the Kodak ICE film processing procedure which repairs many of the defects and scratches in the film. The resultant output is saved into an uncompressed Quicktime ProRes file. That file is then run through our proprietary process which compensates for the frame by frame deltas in textures, colors and lighting. Once the automated scan is completed, our editors then view the video scene by scene, applying Gamma and Lighting corrections. Any remaining scratches or defects are then repaired by hand.

The process is so good that we have taken films mastered in 4K by other studios and given them dramatic improvements by running them through our process. With the new facilities opening next week, I'm sure that there will be samples posted soon on the website showing examples of this process." -Chief Technologist David Foley
