Say it in a prompt

While the video loads, show a small spinner centered over it (8 bars that fade one after another, 0.8s per turn), with the text "Loading video…" under it.

Seen on

  • Apple AirPods Pro 3: The video player shows a loading spinner made of 8 small bars that fade one after another.

You might describe it as

  • spinning circle while waiting
  • loading wheel
  • the thing that spins when stuff loads

Not to be confused with

  • Progress bar

    A spinner only says "wait"; a progress bar shows how much is done.

  • Skeleton screen

    A spinner hides the page while waiting; a skeleton screen shows the shape of what's coming.

  • Preloader

    A spinner is a small sign of waiting inside a page; a preloader covers the whole screen until the site is ready.
