Professional AI Matte Extraction Plugin for OFX
ONYX Ai Matte is a GPU-accelerated matting plugin for DaVinci Resolve, Fusion Studio, Nuke, and Natron — 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.
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
