E-Solutions / SpotTrace Studio
E-Solutions / SpotTrace Studio
An operator watches a fixed camera of the stage and moves one target. Every calibrated moving head aims at the same spot — pan, tilt, zoom and dimmer solved per fixture and sent over Art-Net or sACN at 40 Hz. In the spirit of RoboSpot and Follow-Me, using the lights you already have in the rig.
3-day trial, fully featured. No account, nothing to sign up for.
Calibrate once against tape marks on the floor, and the maths does the rest — camera pixels become stage positions, and stage positions become pan and tilt for every fixture independently.
A webcam or capture device, or any NDI source on the network — PTZ cameras, vision mixers, visualisers. No camera at all? Load a stage plot, top view, photo or PDF and operate from the plan instead.
Enter the coordinates of four tape marks and click them on the floor. Then aim each fixture at those marks and capture. With four or more points it solves the fixture's position in 3D and reports the accuracy in centimetres.
Click, drag or touch the video. Or use a gamepad, MIDI controller, keyboard or OSC. Three independent targets, with handoff crossfades when you move a fixture from one to another.
Everything below is in the shipping build.
Detected people get boxes; click one to lock the active target onto them. A Kalman filter with lookahead compensates for fixture mechanical lag. Manual input always overrides, and a watchdog decides what happens if the person is lost — hold, fade out, or go to the safe preset.
Auto-zoom holds a constant beam diameter and auto-dim holds constant perceived brightness as the distance to the fixture changes.
Draw polygons over the audience or an LED wall with a soft fade edge in metres — beams fade approaching and black out inside. One SAFE button sends every target to a known position.
Load official manufacturer profiles and pick the DMX mode. Pan and tilt with real ranges, dimmer, zoom with real beam angles, iris, focus and colour are mapped automatically; every other channel becomes an extra attribute at its default.
Targets A, B and C each with their own dimmer, enable toggle and AI toggle. Assign any fixture to any target; reassigning crossfades it across.
Art-Net broadcast or unicast, and sACN with settable priority — run above the console to take over pan, tilt and dimmer, then disable to hand control back mid-show.
Bind MIDI CC and notes, keyboard keys, or gamepad axes and buttons to any parameter with a Learn workflow. OSC input for target, dimmer, blackout, presets and target select.
Record the active target's path in rehearsal and play it back, optionally looped, in the show. Nine position presets, colour presets with per-fixture conversion, and quick channel looks.
Worth checking before you plan a rig around it.
| Operating system | Windows 64-bit |
| Camera | Any webcam or capture device, or an NDI source on the network. NDI needs the free runtime from ndi.video installed. |
| Fixtures | Moving heads with 16-bit pan and tilt. Dimmer, zoom, iris and focus optional. GDTF profiles supported; grandMA2 .xml personalities are not. |
| Network | Art-Net or sACN (E1.31) to your nodes or console |
| Calibration | At least four measured marks on the stage floor, and the ability to aim each fixture at them once |
| AI tracking | Optional. The first time it is enabled it downloads the detection model, so that one step needs internet. |
Two builds, same software. Everything runs locally — the only step that ever needs internet is the optional one-off AI model download.
