Broadcast Color Correction Assistant for TV Production
Analyze broadcast specs and generate LUT strategies for multi-episode TV color consistency
What You Can Do
You can rapidly decode broadcast technical specifications (BT.709, HDR standards, platform-specific requirements), generate LUT strategy documentation that maintains consistency across 6-13 hour episodes, and create color decision logs for QC compliance. The skill helps you troubleshoot consistency issues between episodes, analyze failed QC reports, and plan primary correction workflows that meet all delivery specifications before grading begins.
Features
Parse complex delivery specs (BT.709, P3 headroom, black level enforcement) and extract actionable color constraints for your workflow
Create documented LUT approaches for multi-episode seasons with consistency checkpoints and DRT (Display Rendering Transform) planning
Build QC-ready logs of correction decisions, key adjustments, and compliance notes for post-production review
Analyze color variance across episodes and identify technical causes (source material, grading decisions, delivery target mismatches)
Diagnose why episodes failed broadcast QC and generate corrective action plans with specific technical adjustments
Generate platform-specific delivery checklists ensuring your final grades meet SDR/HDR, loudness, and color space requirements
Map out DRT strategy and primary correction hierarchy before grading begins to optimize efficiency
Identify root causes of color inconsistency (source quality, monitoring environment, LUT application) with diagnostic questions
Example Output
Example 1: Broadcast Spec Analysis
Input: AWS Media Services delivery spec for FAST channel
Output:
- Color Space: ITU-R BT.709 SDR required
- Black Level: 7.5% setup (not 0%)
- Peak White: 100 nits (no HDR)
- Loudness: -23 LUFS (EBU R128 — note: color assistant's parallel concern)
- Critical Constraint: No P3 metadata; mastering space must collapse to BT.709 in primary
- Recommendation: Set monitor to 709 from grade start; avoid 10-bit color above Rec.709 gamut
Example 2: LUT Strategy Document
Output:
## Season 1 Color Strategy (8 episodes, 5 production days)
### Primary LUT Approach
- Input: Linear RAW (Alexa, RED)
- DRT: ACES-to-709 (minimal creative LUT in ACEScc space)
- Delivery: 10-bit 709 SDR
### Episode Consistency Checkpoints
- Ep 1-2 (Day 1): Establish look; lock primary LUT
- Ep 3-5 (Days 2-3): Reference Ep 1 on same monitor; document variance
- Ep 6-8 (Days 4-5): Final consistency pass vs. Ep 1 at broadcast specs
### Key Adjustments
- Skin tone reference: Ep 1, 12:34 (close-up of lead actor)
- Shadow floor: Black at 7.5% setup (not true black)
- Saturation cap: 130% (prevent broadcast distortion)
Example 3: QC Failure Diagnosis
Input: Episode 4 failed QC — "Color shift in transition at 23:45"
Output:
- Root Cause: Monitor white point drifted between grade sessions; LUT applied inconsistently
- Technical Evidence: Transition uses secondary node from Day 3; Day 4 grades show +0.2 blue bias
- Fix: Reapply LUT to secondary node; reference Ep 1 at identical monitor conditions
- Prevention: Lock monitor white point before each session; grade all episodes in same room

This skill helps you architect complete color strategies before grading sessions begin. You'll generate detailed shot-by-shot grading maps that synchronize visual mood to dynamic audio, develop LUT strategies for specific music genres with documented creative reasoning, establish technical parameter ranges per scene or musical section, and create mood board documentation that aligns stakeholder expectations early. By treating color as a primary creative element rather than post-production cleanup, you reduce revision cycles and deliver grades that amplify both narrative and musical intent.
