The High-Speed Slow-Motion Frame Rate to Shutter Light Flicker Sizer evaluates proportional relationships, geometric root factors, and percentage distributions between high-speed camera parameters and lighting frequencies.

### Mathematical Evaluation & Formulas The tool computes three direct output metrics based on three user inputs ($V_1$, $V_2$, and $V_3$): - **Primary Proportion Metric ($M_{\text{main}}$)**: Evaluates the product of the first two parameters divided by the third parameter (with a non-zero denominator clamp of $0.01$): $$M_{\text{main}} = \frac{V_1 \times V_2}{\max(0.01, V_3)}$$ - **Geometric Scale Factor ($M_{\text{sec}}$)**: Determines the root-mean-product of the initial two parameters: $$M_{\text{sec}} = \sqrt{\max(0, V_1 \times V_2)}$$ - **Balance / Efficiency Percentage ($P$)**: Calculates the proportional share of parameter 1 within the two-parameter sum, clamped between 0% and 100%: $$P = \min\left(100, \max\left(0, \frac{V_1}{V_1 + V_2} \times 100\%\right)\right)$$

> Note: True cinematic flicker mitigation on production sets requires synchronizing camera shutter speed to exact electrical mains frequencies ($50\text{ Hz}$ in PAL regions or $60\text{ Hz}$ in NTSC territories) and ballast PWM cycles. This utility computes the specific mathematical ratios defined above.

### Worked Calculation Example Consider input values of **$V_1 = 100$**, **$V_2 = 20$**, and **$V_3 = 5$**: 1. **Primary Metric**: $$M_{\text{main}} = \frac{100 \times 20}{5} = \frac{2000}{5} = 400.00$$ 2. **Geometric Factor**: $$M_{\text{sec}} = \sqrt{100 \times 20} = \sqrt{2000} \approx 44.72$$ 3. **Balance Percentage**: $$P = \frac{100}{100 + 20} \times 100\% = \frac{100}{120} \times 100\% \approx 83.33\%$$
