I'm glad we've established that 4K Studios can only produce faked 4K files that are upscaled from 2K data streams. Thus these 4K Studios' files cannot be certified with the 4K ribbon or logo - as they are not real 4K, just upscaled 2K files.

Except it's dead wrong. The scan unit of The Director is only able to transfer to the computer unit of The Director at 2K max resolution. So the "4K" files that are output from The Director are at best UPSCALED from a 2K raw datastream from the scan unit.

The native scan resolution output from the scan unit component is limited to 2K maximum. That's a simple fact.

SPECIFICATIONS

Imaging System (NOTE: THIS IS THE SCAN UNIT PART OF THE DIRECTOR)
High MTF resolution adjustable focus lens
12 µm x 12 µm scanned pixel size on film (2K)
6 µm x 6 µm scanned pixel size on film (4K and 16mm) Note - it can scan 4K digital-to-film filmstock that studios which shoot in digital and then make film prints of it for theaters without digital projection that still use 35 mm projectors)
10-bit log or 16-bit linear bit depth (data format dependent)
4:3, 16:9 and 1.85 aspect ratios
2K, HD and SD output resolution
Triple-Flash High Dynamic Range (HDR) scanning

All The Director can output is content that is UPSCALED 4K or non-upscaled 2K, HD and SD. The Director uses CineDirector™ software for the 4K upscale and then for all the compression formats.

Butt is it UPSCALED from a max 2K datastream from the scanner unit. It can never be true 4K. Ever. Only UPSCALED 4K from a 2K or less data feed.

As I've stated before, a full 4K datastream at 60fps with 16-bit depth is 36.7 Gb/s. And the scanner does multiple scans per frame - so multiply by that number (I think NTEK claims 11 scans per frame!). So 11 times 36.7 Gb/S times 11 if scanned real time - 403.7 Gb/sec!!! Of course if a 2 hour film is scanned at 11 scans per frame, EVEN IF there were any interconnect and processor that could handle 36.7 Gb/s it would take at least 22 hours to scan one film. Butt there is nott an interconnect or processor in The Director that can handle even one-tenth of that datastream rate.

Look a the top interconnect speed in the leading supercomputers (16 Gb/sec - going up to 80 Gb/s in the FUTURE):

These are multimillion dollar machines.

The interconnect in a lowly old $250k The Director is a lott smaller than 16Gb/sec - WAY, WAAAY less bandwidth.

Nowhere near 36.7 Gb/s needed for 4K 60 fps 16-bit depth - and 403.7 Gb/s with 11 scans/frame.

So the scanner component in The Director only feeds a 2K datastream to the linked computer component of The Director.

The Director then UPSCALES from this 2K data into a 4K upscaled file.

FACT. 4K Studios in incapable of making true 4K scans!
