01
Lock on
Tap your subject in the live preview. Helm locks on with Apple Vision and keeps following the same person, even when someone walks between you.
How it works
Tap a person and the rig follows.
The camera itself moves; there’s no digital crop. Tracking runs entirely on your Mac, with no cloud and nothing to wear.
02
The rig follows
Motors pan and tilt the camera to hold the framing. The rig stays still while your subject is still, and moves smoothly when they do.
03
Walk the room
Cross the stage, work the whiteboard, sit back down. A walking subject gets room to move into, and the frame settles when they stop.
Features
The details.
The tracking is tuned against a measured model of the physical rig, then verified on the real thing.
Motion
Two-axis smooth tracking
Pan and tilt are driven together and tuned for steady, deliberate movement. No hunting, no stop‑start.
Framing
Head-anchored framing
Helm frames on the head, not the bounding box, so headroom stays natural as your subject steps closer or farther away.
Anticipation
Lead room
A walking subject is framed with room to move into. When they stop, the shot recenters smoothly.
Control
MIDI jog
Trim the shot from a MIDI controller whenever you like. Helm folds the adjustment into the frame and keeps tracking.
Developer
Mock-hardware dev mode
A developer simulator with a virtual rig and mock serial hardware, so you can tune and test with nothing plugged in.
