Why Multi-Person Motion Tracking Online Works Here
Tracks several people at once
Multi-Person mode uses a dedicated multi-pose model so more than one skeleton is tracked simultaneously.
Stable IDs across frames
Each tracked person keeps a consistent ID frame to frame, so Color by ID can give everyone their own color.
Per-person effects
Angel Glow, Hand Spiderwebs, Head Halo, Gesture Labels, and Joint Angles all work per-person, independently.
Object mode counts people too
Switch to Object Detection with the Person class filter for simple box-based multi-person counting instead of full skeletons.
Works on recorded footage too
Load a group video instead of a live camera — same multi-person tracking applies.

Frequently Asked Questions
How many people can it track at the same time?
Pose mode with Multi-Person on tracks several skeletons at once, and Object and Motion modes have no fixed limit — the practical ceiling is how much people overlap and how fast your device can process each frame.
Does each person keep their own colour?
Yes. Colour by ID gives every tracked person a stable colour, and tracking holds that ID across frames so two people crossing paths do not swap.
What happens when two people walk past each other?
Tracking resolves the closest pairings across the whole frame at once rather than in detection order, which is what keeps IDs stable through a close pass. Track Persistence also keeps a briefly hidden person on screen instead of flickering out.
Can I draw connecting lines between people?
Yes. Connect and Constellation draw lines between tracked objects, with distance and line-count limits so a crowded frame does not turn into a solid mesh.
Is this multiplayer over a network?
No — it means several people in one camera frame. Everything runs on one device and nothing is sent anywhere.
