NTEk released this news in March 2015. There was a leak of snapshot of Ultraflix "work in progress" version showing the many titles from Millennium films. IMO many of those are ready with a click of a switch and just awaiting approval from directors and producers. Besides, scanning a 2500 foot film reel with 3 frames per second will definitely take time. There is also scanning of the audio part and synching it with the movie. Then there is the cleaning of scratches and dirt. Then there is color correction and encoding process into HEVC then uploading it to the server. One movie takes 5-6 terabytes (6000gigabytes) of space. That's a lot of data for trasfer.
One just has answer this question>> " if it's so easy to process a film and convert it to 4k then why Billion dollar companies with all their money CAN NOT get them any faster?"
