This is a free animation of TV static, also known as “snow noise”—a visual phenomenon from analog television. It appears when the TV fails to receive a proper signal due to interference, weak transmission, or lack of broadcast input.
The flickering dots and hissing sound became iconic in the era before digital broadcasting. Technically, the effect is caused by electromagnetic noise from various sources, including atmospheric conditions, terrain, or nearby devices. Despite its functional origin, the static visual has been repurposed in modern media as a symbol of mystery, horror, or nostalgia.
Use this animation for retro scene transitions, horror game overlays, or signal-loss effects in video storytelling.
