DCI 2K/4K Container Calculator
See the exact active-image pixels for Flat (1.85) and Scope (2.39) inside the DCI 2K and 4K containers — the numbers a DCP must conform to.
A DCP's image must land on exact DCI rasters: 2K Flat is 1998×1080, 2K Scope 2048×858; 4K doubles both. Get one pixel wrong and the package fails validation. The container is always 2048×1080 (or 4096×2160) — Flat and Scope are the active windows inside it.
