VFX Compositing Technical Review & QA Framework
Systematically QA compositing projects for technical issues and delivery spec compliance
What You Can Do
You can conduct rigorous technical audits of completed compositing work using industry-standard checklists that catch common failure points like banding, color shifts, matte errors, and spec violations. This framework works across any compositor's toolset (Nuke, After Effects, Fusion) and provides systematic documentation for revision requests, ensuring your deliverables meet technical standards and avoid costly revision rounds.
Features
verify layer naming conventions, organization, locked/disabled states, and unnecessary layers that could cause downstream issues
check color space consistency, bit depth accuracy, LUT application, and gamma handling across the composite pipeline
inspect for common artifacts like banding, compression noise, edge fringing, and verify frame ranges match delivery specifications
validate alpha channel cleanliness, edge quality, feathering consistency, and premultiplication correctness
confirm resolution, frame rate, color space, bit depth, metadata, and file naming against delivery requirements
generate structured reports categorizing issues by severity and deliverable impact for efficient revision tracking
final pass covering file exports, color grading relationships, motion graphics integration, and playback consistency
aligns QA process with VFX supervisor expectations and common facility standards
Example Output
Composite QA Report Example:
✓ Layer Management: Hierarchy clean, naming consistent (COMP_BG_CHAR_FX_v002), pre-comps properly labeled
⚠ Color Science: DCI-P3 color space confirmed, but LUT application shows 1.8 gamma in grade layer instead of 2.2 linear—requires correction
✗ Rendering Issues: Frame 847-852 shows banding in sky gradient (8-bit export detected; recommend 16-bit), edge matte on character has 2-pixel fringing on frame 1024
✓ Matte Integrity: Alpha channel clean, premultiplication correct, edge quality passes 2K+ inspection
✗ Spec Compliance: Delivery spec requires ProRes 422 HQ with embedded color profile; current export is 8-bit uncompressed. Revise export settings.
Priority Fixes: 3 critical (gamma, banding, spec), 1 warning (edge fringing—minor impact)

You can break down video content into individual frames and aligned audio segments at any interval you specify. This skill generates PNG images for visual analysis, extracts corresponding audio clips in AAC format, and creates a JSON manifest that maps every frame to its timestamp and audio file—perfect for preparing video content for detailed review, transcription workflows, or handing off to other agents for automated processing.

You'll design dynamic audio systems that shift music and sound effects in real-time based on gameplay intensity, player decisions, environmental conditions, and narrative branching. This skill guides you through building adaptive mixing strategies, stem-based music systems, and procedural audio routing that keeps audio responsive without becoming chaotic—allowing you to maximize asset reusability while maintaining sonic coherence across unpredictable gameplay states.

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.
