Clock ticking is one of the most widely used sound effects in video editing because time itself is a universal visual shorthand. Creators use it to signal waiting, deadlines and suspense without needing dialogue or music, from short-form countdown edits to longer sketches where a character is stuck in an awkward pause. Its steady rhythm is easy to loop, layer under narration, and cut for comic timing, which is why it keeps appearing in memes, tutorials and reaction videos long after countless other effects have faded.
