iPhone video level tool

The tool analyzes iPhone video captures to quantify exposure, luminance distribution, highlights/shadows, white balance, and color saturation. It targets mobile filmmakers, editors, and on-location shooters who need quick, device-agnostic evaluation to guide tweaks or LUT choices.
It operates conceptually by mapping input camera metadata and scene lighting to measurable metrics (exposure, balance, saturation) and by comparing them against reference baselines. It does not edit footage; it produces actionable notes and scores to inform shooting and grading decisions.
Core value lies in portability and consistency: measurements require only a frame sample or short clip, regardless of hardware, and results are reproducible for quick cross-device parity. Typical use cases include on-site exposure validation, pre-shoot test shots, and post-shoot quality checks for social content across iPhone models.
Key features include numerical exposure_score, luma_histogram, clip_alerts, wb_delta, and suggested_exposure_adjustment, plus concise grading_notes to guide color decisions. Advanced workflows can extend to batch analysis and export to JSON for pipeline integration.
