LED screens for camera and broadcast: refresh rate, moiré and the right pixel pitch
Three things decide how an LED screen looks on camera: a high refresh rate, a pixel pitch suited to the camera distance and correct camera settings. A low refresh rate shows as lines and flicker; moiré depends on pitch, focus and camera distance. The model's refresh rate is listed in the datasheet sent with the written quote.
Short answer: Three things decide how an LED screen looks on camera: a high refresh rate, a pixel pitch suited to the camera distance and correct camera settings. A low refresh rate shows as lines and flicker; moiré depends on pitch, focus and camera distance. The model's refresh rate is listed in the datasheet sent with the written quote.
What is refresh rate?
Refresh rate is how many times per second the LEDs are driven, in Hz. The eye does not notice low values, but a camera sensor with short exposure captures the refresh. Screens that will be filmed therefore use high-refresh drivers and control cards.
What is moiré and how to reduce it
Moiré is the wavy pattern that appears when the screen's pixel grid overlaps the camera sensor grid. Keep the screen slightly out of the focal plane, angle the camera a little instead of square-on, change the camera distance or focal length, and choose a fine pitch suited to the distance.
Camera settings: shutter, frame rate, sync
Run a short camera test while content plays. If you see lines, adjust shutter speed and frame rate to match the screen refresh; values matched to the local mains frequency usually reduce flicker. For multi-camera productions mention sync needs at the survey; the controller configuration is set in the quote.
Pixel pitch and camera distance
The closer the camera, the finer the pitch. Our fine-pitch options are P1.25, P1.53 and P1.86 GOB; for wider shots indoor P2.5 is considered. Published prices: P1.25 GOB USD 115.06, P1.53 GOB USD 74.50, P1.86 GOB USD 58.90 (per panel, VAT included; shipping and on-site installation excluded).
Choosing the controller
We offer NovaStar and Colorlight controller families; the right configuration depends on camera count, source resolution and screen size and is specified in the quote.
Uses
TV and podcast studios, wedding and event filming, corporate live streams and product shoots. We plan camera position and distance together at the survey.
Why does an LED screen flicker on camera?
When the screen refresh rate and the camera shutter and frame rate do not match, the camera records the refresh as lines or flicker. A high-refresh screen and correct settings prevent it.
How do I avoid moiré?
Keep the screen slightly out of focus, change camera angle and distance, and choose a fine pitch suited to the distance.
What is the refresh rate of NXTIONSTAR models?
Per-model refresh rate and other technical values are shared in the datasheet with the written quote.
Which pitch suits a studio?
For close shots P1.25, P1.53 or P1.86 GOB; if the camera is far from the screen, indoor P2.5.
