Laser transition sounds come from the wider library of science-fiction effects that became standard in online video editing, where a short zap is used to signal movement between shots. As short-form video, gaming montages and reaction edits grew, editors began reusing the same clean, futuristic sweep because it reads instantly, even on phone speakers. It has no single famous scene or character behind it, which is why it works across vlogs, tutorials, memes and gameplay clips without tying the edit to one franchise or joke.
