Keyframe 2 of a portal-transformation sequence for a family kids' series. Extreme close-up inside a swirling blue-violet light tunnel: two children's outstretched left wrists side by side, wearing exactly the two watches of image 1 (girl: cream rounded-rectangle watch with a blue smiley screen and coloured stripes; boy: silver rectangular band). Both screens blaze violet and turquoise, and a bright glowing RING OF LIGHT bursts out of the watches and starts sliding up the forearms. Where the ring has passed, the hands are already turning into stylized 3D animated (Pixar-like, smooth, soft) hands in white-and-purple sleeves (look of image 2); ahead of the ring the skin and sleeves are still photoreal. A clear visible seam of light between real and animated. Sparks, speed streaks. 16:9, no text, no watermark.
