I was discussing with a friend the differences between real and fake 4K, and just how many 4K Blurays out there are generating the maximum true blue, and how many are flim-flamming with HDR-enhanced 2K uprez product, which seems to be good enough for most customers. There’s a half-decent site (Real or Fake 4K) that examines the particulars. Everyone says how great the Revenant 4K Bluray looks, but even this visually dazzling tour de force isn’t a pure experience. Real or Fake 4K says that while “films shot with 2.8K camera have more than twice the pixels as an ordinary 1080p Bluray”, The Revenant was “shot in 3.4K (some scenes 6.5K), VFX-rendered in 2K with the digital intermediate done in 4K” — obviously close but not quite an absolutely pure 4K cigar. The friend recommended that I buy Panasonic’s 4K UHD Bluray player — DMP-UB900 — for $600 and change, and right away I thought “no way.” Not until an abundant library of pure 4K Blurays of quality-level films are available, preferably with a good percentage of the classic stuff shot in large-format celluloid (70mm, VistaVision, et. al.). And that price has to come down.
