Recording a concert screen often looks simple in the moment, yet the footage can quickly become unusable because of a moving black line or visible flicker. The problem is common when fans point a smartphone at a giant LCD or LED display instead of the main stage.
That issue is not always a sign that the phone camera is broken. In coverage of EXO’s EXhOrizon concert at Indonesia Arena, the flicker disappeared after one key setting was changed: shutter speed.
Why concert screens flicker in video
LCD and LED screens refresh very quickly, but that refresh cycle does not always match the shutter speed of a smartphone camera. When the two are out of sync, the camera captures only part of the light cycle, and that creates dark bands or a flickering effect in the video.
The more the shutter speed conflicts with the screen’s refresh rate, the worse the flicker becomes. In other words, the black lines in concert footage usually point to a settings mismatch, not a damaged sensor.
This becomes especially relevant in venues where the side screens are the clearest way to capture the artist’s face. For many concertgoers, those displays are more useful than the stage itself, particularly when seating is far from the performance area.
The simple fix on Galaxy S26 Ultra
During testing with a Samsung Galaxy S26 Ultra, the initial setup used UHD 60 fps, ISO 200-600, and shutter speed between 1/180 second and 1/250 second. Those settings are well suited for sharp stage action and fast dance movements.
Once the camera was aimed at the concert screen, however, the footage was filled with black lines. The solution was to use Pro Video mode and slow the shutter speed from 1/280 second to around 1/60 second.
As soon as the shutter speed was lowered, the flicker vanished. The screen looked normal again, and the footage became much cleaner.
That change also made it easier to capture facial detail, expressions, and movement on the display. For fancam-style concert recording, that matters because many fans are trying to get close-up visuals from the jumbotron rather than a wide shot of the stage.
Why the best setting is not always the same
The ideal shutter speed can vary from one concert to another because screen types are not identical. In some events, 1/90 second or 1/125 second may already be enough to reduce flicker.
That means the adjustment should be treated as a quick on-site experiment rather than a fixed rule. If the black bands remain visible, the shutter speed can be lowered further until it matches the screen more closely.
The method is most useful for fans seated at the side or back of a venue, where the main stage may be difficult to view clearly. In those situations, the extra LED screen often becomes the primary visual subject for recording.
It is also important to separate this use case from recording dancers or performers directly on stage. Fast movement usually needs a higher shutter speed for sharpness, while a screen recording often benefits from a slower one.
On the Galaxy S26 Ultra, the slowest setting available in the test was 1/60 second. In that setup, the concert screen stayed clear, and the flicker problem was effectively removed.
