Keyframe 1 of a portal-transformation sequence for a family kids' series. Photorealistic live-action children (exactly Kira and Yan as in images 1-4: Kira 7 y.o., two dark buns, violet/turquoise thin braids, pink cape with a blue K badge, denim skirt; Yan 13 y.o., glasses, navy zip hoodie, light jeans) tumble head-first INTO a swirling blue-violet light tunnel (colour of the portal in image 2). Dynamic camera from just behind and above them, as if chasing them: Kira's pink cape streams back towards the lens, Yan's hoodie flaps, light streaks rush past, their outstretched arms reach into the bright centre, they glance back at each other thrilled. Motion blur on the tunnel walls, sharp faces. Cinematic, 16:9. No text, no watermark.
