And if what you say is true…
Hi yotsuya,
I’m sorry, I don’t want to argue with you, I’m just reading and believing what ILM HD Supervisor Fred Meyers said about this matter, and I’m assuming it is true: “This chroma sub-sampling combined with spatial sub-sampling effectively reduced HD’s 1920 resolution to 1440 for luma and 960 for chroma.”
About the ideal scanning resolution, as I said before: even if the original master was shot in 6k, after going through a traditional Intermediate Positive, then to IN to release print stage in the lab, it wouldn’t go above 2K. Plus the weave and lack of pin-registration in most projectors, plus the less-than-optimum focus, you could easily wind up with well below 1080 resolution.
Believe me, I’m currently scanning The Phantom Menace in 4K: there is nothing to get more than in 2K (and Harmy seems to think the same).
