Zoom in zoom out sounds have become a staple of short-form video editing because they mimic the quick push and pull of a camera in a way viewers instantly recognise from memes and reaction clips. Editors use the paired movement to signal focus, surprise or irony, often in TikTok, Reels and YouTube Shorts where a fast visual gag needs to land in seconds. Its popularity endures because the effect is simple, flexible and works without words, making it easy to reuse across pranks, gaming highlights, commentary and everyday comedy edits.
