TECHNICAL TOOL
Start with the LED wall. Get practical camera settings.
Enter parameters normally available in VMP or from the LED technician. The tool ranks standard camera frame rates and gives a shutter starting point.
CAMERA STARTING PROFILE
Exact 2:1 reference / camera relationship.
Set camera sensor sync to Genlock.
Set camera FPS and shutter to the values above.
If supported, enter the same shutter value in COEX Shutter Fit.
Start COEX Phase Offset at its default 0°; use it only as the final physical trim.
The wall parameters support a practical starting profile.
Exact 1:1 synchronization, but the shorter exposure needs more light and may reveal LED timing more easily.
Use only when the wall and master clock can be changed to the same rate family.
ARTEFACT RISK
Common Genlock keeps the frame relationship stable.
Refresh, scan and brightness determine the starting risk.
LED pitch is close to the camera sampling scale.
2.1 camera px / LED pixelIndividual LED pixels are unlikely to dominate at this geometry.
Geometric estimate only. Camera-format presets use an approximate active width; focus, aperture, OLPF, Bayer pattern, panel RGB layout and crop/readout mode can move the real moiré boundary.

METHOD REVIEWED 13 SEP 2026
LED refresh, scan, brightness, pixel pitch, Genlock, Shutter Fit availability and camera geometry come from the user. The tool does not read VMP, a camera or an NCP.
Frame-rate relationships, exposure time and the shutter angle nearest to whole nominal refresh periods are calculated from those inputs.
Rate ranking, capture-condition labels and geometric moiré risk are PixelSentinel starting heuristics. They are not NovaStar ratings or measured cabinet performance.
Confirm PWM/scan banding, sensor readout, focus, aperture, OLPF, Bayer sampling, LED RGB layout, the actual NCP and final Phase Offset on the specific camera and wall.
The ranking evaluates frame-rate compatibility. Shutter is fitted near 180° to the nearest whole number of nominal LED refresh periods, then rounded to a realistic 0.1° camera setting. Begin Phase Offset at its default 0° and use it only as the final physical trim.
These documents support the COEX, Genlock, Shutter Fit, Frame Rate Adaptive and cabinet/NCP context. They do not validate PixelSentinel's rate-ranking or moiré heuristics.
