Loading Spinner Circle UI Overlay Black Background 4K Vertical - 4K 影片檔

A clean circular loading spinner in the centre of the frame: a bright arc chasing round a faint ring, stretching and easing as it turns, with a Loading label and animated dots underneath. Small and centred, so it sits over a frozen screen, a video intro or a waiting moment. Generic placeholder labels, no app, platform or brand names. The background is true black (#000000) edge to edge with no vignette or grain: set the layer to Screen or Add and only the interface stays over your footage. Seamless 15-second loop. Vertical 9:16 cut for reels, stories and phone screens.
