## What this tool does
Tune brightness, contrast, saturation and warm/cool temperature — one pass, no editing suite.

## Typical user problems
- Flat log footage, a dim indoor shot or a tungsten-lit room that came out orange — these need the same four sliders every editor exposes: brightness, contrast, saturation and color temperature. The eq and colorbalance filters apply them in one re-encode with publish-ready H.264 output.

- contrast: number (range 0.5-2), required. 对比度
- saturation: number (range 0-3), required. 饱和度
- temperature: number (range -1-1), required. 色温（暖 + / 冷 −）
