Professional AI Matte Extraction Plugin for OFX

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

Powered by Meta SAM3 with the VitMatte and MEMatte refiners, it runs one unified pipeline: text, point, box and mask prompts work together in a single scene, and objects track across frames automatically.

Installing on Windows, macOS or Linux, activating a license and every parameter explained: see the ONYX Ai Matte documentation.

HOW IT WORKS

Type an object name — "person", "car", "dog" — and SAM3 instantly finds every instance in the frame. Click to select specific objects, extract them all at once, or switch to direct point or box selection for precise control — all in the same node. Once defined, objects track across frames on their own.

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

KEY FEATURES

• Unified Pipeline — Box, Point, Text and Mask prompts in one scene, up to 16 objects
• Text Prompts — Type any object class (or several, comma-separated) to detect all instances automatically
• Point Selection — Click to segment a specific object; positive/negative points for refinement
• Bounding Box — Draw a box for quick rectangular selection
• Mask Prompt Input — Track a mask you already have: a one-frame roto becomes a fully tracked matte (works for sub-objects too — a sleeve, a car door); move the mask mid-track and a correction key is set right on that frame
• Object Tracking — Masks propagate across frames automatically; four tracking modes for any shot
• Object Manager — On-canvas panel to solo, keyframe visibility, refine and delete objects
• Trimap + HQ Refiner — Automatic trimap from the masks; VitMatte/MEMatte refine the edges
• Refiner Direct Input — Connect any matte (your roto, or a mask tracked in Mocha or another system) straight to the refiner for cinema-quality alpha edges
• Dual Refiners — VitMatte (default) and MEMatte, switchable instantly — pick the best for your footage
• TensorRT Acceleration — 3-4x faster refiner inference on NVIDIA RTX GPUs
• Temporal Smoothing & Edge Stabilization — Reduce flickering across frames for clean motion
• Edge Controls — Feather, shrink/grow, offset, levels, binary threshold for fine-tuning
• Overlay Preview — Real-time mask preview with customizable colors
• Bake to Disk — Cache masks to disk; reopen the project and play back with no engine and no VRAM

PERFECT FOR

• Multi-character scenes: find all people, solo specific actors
• Complex hair and fur extraction with cinema-quality edges
• Fast commercial turnaround with text-first discovery
• 4K+ compositing in Nuke, DaVinci Resolve, Fusion Studio, Flame and Natron
• Edge-refining external mattes (roto, planar-tracked) via the Refiner Direct workflow
