Scope / Flat Active Pixel Calculator
Within a fixed container, compare how many active pixels Flat (1.85) vs Scope (2.39) use and the height difference for hard-matte decisions.
In the 2048×1080 DCI container, Flat (1.85) fills the width and is 1107→1080 tall, while Scope (2.39) fills the height and is 2048 wide but only 858 active. Scope therefore has fewer total active pixels but a wider field of view — the framing-vs-resolution trade every DCP master decides.
