Light modulation on spectator seating areas may also be clearly observed in high frame rate broadcast pictures and should be eliminated whenever possible. The flicker caused by the light modulation is distracting and impairs the viewer’s experience. The circumstances that produce the flicker will vary depending on the modulation of the flicker, the alternating voltage frequency and the camera frame rate.

It should be noted that, in stadiums where the pitch illuminance system is observed to be flicker-free when using high frame rate cameras, there will still be background flicker in broadcast pictures if the light falling upon the spectator areas is not flicker-free. We recommend that you assess the illuminance on the spectator areas and change them to flicker-free where appropriate.
