What happens when you use a 2.0x anamorphic lens on a 16:9 sensor?

A 2.0x anamorphic lens on a standard 16:9 (1.78:1) sensor produces a super-wide 3.56:1 frame. To deliver in 2.39:1, you must crop off roughly 33% of the sides of the frame.

Understanding Your Results

Calculates final uncompressed desqueezed aspect ratio, square-pixel timeline editing resolution, standard 2.39:1 Cinemascope delivery canvas, and frame crop loss percentage.

Practical Guidance & Next Steps

Shooting 2.0x squeeze lenses on 4:3 open-gate sensors produces a native 2.66:1 frame that requires only a modest 10% horizontal crop to achieve standard 2.39:1 Cinemascope.

What is this?

A cinematography geometry utility that calculates anamorphic lens desqueeze dimensions and timeline editing resolutions.

How does it work?

1. Select camera sensor mode (4:3 Open Gate, 3:2 Full Frame, 16:9, 17:9 DCI). 2. Select anamorphic lens squeeze factor (1.33x, 1.5x, 1.6x, 1.8x, 2.0x). 3. View final desqueezed ratio, timeline resolution, and 2.39:1 crop loss.
