What does my anamorphic capture actually deliver?
Enter your capture resolution, squeeze factor, and delivery aspect ratio to see the unsqueezed frame and how much a crop or letterbox mode removes or leaves unused.
Answer
Calculate a result to see whether delivery removes width, height, or adds bars.

Two rectangles, kept separate
Anamorphic framing begins with a squeezed capture rectangle and ends with an unsqueezed delivery rectangle. The squeeze factor changes the displayed aspect ratio; the delivery ratio can then require a crop or unused area. Keeping those stages separate prevents a composition that looks safe on set from losing a critical edge after desqueeze.
A 4096×2160 capture with a 1.33× squeeze becomes about 5448×2160 before delivery framing, roughly 2.52:1. Delivering at 2.39:1 in crop mode removes about 5.23 percent of width. That is geometry, not a quality verdict. Record the exact squeeze convention, frame with a safe overlay, and test a real clip through the intended desqueeze and delivery path.
This result models the values you entered. It cannot see the scene, verify focus or movement, predict camera-specific processing, or guarantee the final photograph. Use it as a stated starting point, then check the important subject area in a test frame or proof.
Make one controlled test with the important variable held constant. Inspect the subject detail, motion, highlights, and intended output, then adjust the setting that protects the priority you named.
FAQ
- Will this tell me whether an anamorphic lens covers my sensor?
- No. It plans frame geometry. Verify image circle, adapter, and lens documentation separately.
- Is this a guarantee?
- No. The result is bounded by the inputs and assumptions shown on the page. It is designed to support a better next decision, not replace a test, measurement, proof, or professional judgement where one is needed.
