Austin, I am not familiar with the internal workings of film recorders to claim knowledge; but I have discovered that different 4K film recorders can have different size lights which effect the brightness and the amount of detail that the film recorder sensors can pick up - thus the actual effective resolution the recorder has. I believe that the 4K figure is in LPI or line pairs not ppi; and it reflects the traditional printers measures for halftone screens which are from 1.5 to 2.0 times the number of raw undithered non-halftoned pixels per inch, dots per inch, or samples per inch as measured along the long side of the film..

It appears to me that the 4k figure for the filmrecorder is simply the size of the sensor, and it doesn't relate to any PPI....and when recording to 35mm, you get 4k on the long side, and when recording to 6cm film (say 6x7) you get 4k on the 7cm side of the film... At least that's my understanding I got from the discussion with Mac.
