Anamorphic Desqueeze Explained
What Is Anamorphic Squeeze?
Anamorphic lenses use cylindrical glass elements to optically compress — squeeze — a wide horizontal field of view onto a standard sensor area. The sensor records a distorted, narrower-looking image; the squeeze must be reversed in post-production to restore correct proportions. This reversal is called desqueezing.
Shooting anamorphically gives you wider coverage from a given sensor, classic oval bokeh, and horizontal lens flares — all of which are preserved once the image is desqueezed back to its intended ratio.
The Desqueeze Formula
Multiply the recorded width in pixels by the lens squeeze factor:
For example, a 1920 × 1080 recording made with a 2× anamorphic lens desqueezes to 3840 × 1080 — a 3.56:1 aspect ratio.
Common Squeeze Factors
| Squeeze | Lens type | Example: 1920 × 1080 recorded |
|---|---|---|
| 1.25× | Mild adapters (Moment, Sirui entry-level) | 2400 × 1080 → 2.22:1 |
| 1.33× | Most entry-level anamorphic adapters | 2554 × 1080 → 2.37:1 ≈ 2.39:1 |
| 1.5× | Some medium-format adapted lenses | 2880 × 1080 → 2.67:1 |
| 1.6× | Vintage scope and specialty anamorphics | 3072 × 1080 → 2.84:1 |
| 1.8× | Specialty cinema anamorphics | 3456 × 1080 → 3.20:1 |
| 2× | Classic cylindrical primes (Kowa, Lomo, Hawk) | 3840 × 1080 → 3.56:1 |
