Anamorphic cinematography lenses optically compress wide horizontal vistas onto narrower camera sensors using cylindrical lens elements, requiring digital de-squeezing during post-production monitoring and editing. This calculation utility evaluates a three-variable engineering index ratio model to project dimensional scale factors, geometric root balances, and aspect retention percentages across camera rig configurations.

### Three-Parameter Index Model The calculator processes three user-configurable parameters: - Calculated Scaling Factor: Scaled output computed as (Primary Dimension * Operating Coefficient) / Safety Factor. - Root Factor: The geometric mean of primary dimension and operating coefficient, sqrt(Primary Dimension * Operating Coefficient), indicating balanced proportional scale. - Aspect Retention Index: Proportional percentage of primary dimension against combined load: Index Ratio = (Primary Dimension / (Primary Dimension + Operating Coefficient)) * 100

Note: This tool computes a mathematical index ratio model based on the three numeric inputs. It does not perform live video pixel de-squeezing or render frame buffer rasters.

### Worked Numeric Example Consider an anamorphic rig evaluated with the following test parameters: - Primary Dimension / Load: 140 - Operating Coefficient: 18 - Safety / Rate Factor: 6 - Calculated Result: (140 * 18) / 6 = 420.00 - Root Factor: sqrt(140 * 18) = sqrt(2520) = 50.20 - Aspect Retention Index: (140 / 158) * 100 = 88.61%

### Client-Side Processing Note All mathematical operations evaluate locally in client-side JavaScript. No camera settings, frame resolutions, or calculation inputs are sent across external networks.
