Professional AI Matte Extraction Plugin for OFX

ONYX Ai Matte is a GPU-accelerated matting plugin for DaVinci Resolve, Fusion Studio, and Nuke — built for VFX artists who need production-quality mattes without hours of manual roto work.

Powered by Meta SAM3 and VitMatte, it combines text-based object discovery with point and box selection for a flexible, fast workflow that adapts to any shot.

HOW IT WORKS

Type an object name — “person”, “car”, “dog” — and SAM3 instantly finds every instance in the frame. Then click to select specific objects, extract all at once, or switch to direct point or box selection for precise control.

VitMatte then refines edges to production quality: hair, fur, transparent surfaces — handled automatically.

KEY FEATURES

• Text Prompts — Type any object class to detect all instances in frame automatically
• Point Selection — Click to segment specific object; positive/negative points for refinement
• Bounding Box — Draw a box for quick rectangular selection
• Trimap Generation — Automatic trimap from SAM3 masks (Text & Box modes); VitMatte refines edges automatically
• Trimap Input — Connect Roto mask as trimap input; VitMatte refines alpha edges to cinema quality
• VitMatte Refiner — High-quality edge refinement for hair, fur, and complex boundaries
• TensorRT Acceleration — 3-4x faster VitMatte inference on NVIDIA RTX GPUs
• Temporal Smoothing — Reduces flickering across frames for clean motion sequences
• Edge Controls — Feather, shrink/grow, offset, binary threshold for fine-tuning
• Overlay Preview — Real-time mask preview with customizable colors
• Cache System — Smooth scrubbing and playback during review
