Cinematic Color Grading Assistant
Systematic color grading for cinematic projects using LUT creation and shot-matching
What You Can Do
You'll develop a complete color grading workflow that bridges creative intent with technical precision. Claude guides you through color space analysis, LUT creation, shot matching across multiple cameras, and waveform/vectorscope verification to ensure consistent, broadcast-compliant results with measurable corrections rather than subjective eye-matching.
Features
Identify and document color profiles, gamma curves, and white balance baselines using technical diagnostics
Create custom 3D LUTs from reference footage that maintain consistency across different cameras, lenses, and shooting conditions
Systematically match shots across multiple cameras and shooting days using vectorscope and waveform anchoring
Interpret technical analysis tools to make measurable corrections aligned with broadcast/streaming standards
Troubleshoot acquisition issues and establish baseline corrections before creative grading
Generate color-correct masters for DCP, streaming, and broadcast formats with technical verification
Use industry-standard terminology and diagnostic documentation to align grading decisions with creative vision
Minimize revision cycles by anchoring decisions in technical measurements rather than subjective assessment
Example Output
Example 1: Shot-Match Documentation
- Scene: Dialogue over 3 cameras (Alexa, RED, Sony FX30)
- Waveform reference: Skin tone peak at 60-65 IRE, black at 5-10 IRE
- Vectorscope targets: Skin tone cluster 120-130° hue, ±15° saturation variance
- LUT adjustments per camera with before/after waveform comparisons
- Delivery specs: Rec.709 for streaming, DCI-P3 for DCP with metadata
Example 2: White Balance Correction
- Outdoor daytime mixed lighting (sun + practical tungsten)
- Kelvin shift analysis: 5600K sun vs. 3200K practicals
- Correction matrix: +350K global shift + localized secondary color isolation
- Verification: Vectorscope clustering within ±8° hue drift
Example 3: Creative Grade Handoff
- Base LUT applied across 45 shots over 3 shooting days
- Deviation matrix showing which shots required secondary corrections
- Director-approved reference stills with technical specifications for colorist sign-off
