First-person ping pong rally with silver-haired opponent, Seedance 2.0

Create a 15-second ultra-realistic vertical video in strict 9:16 format, single continuous shot, first-person perspective POV. Realistic iPhone 17 handheld phone shooting texture, high-definition clarity, 4K quality, natural indoor lighting, realistic motion blur, sharp subject detail. No cinematic commercial look, no anime, no cartoon, no 3D render, no game-engine look. Reference: image1 = female lead identity reference. Use image1 as the strict identity reference for the female lead throughout the entire video. Preserve her exact face, facial proportions, hairstyle, hair color, body proportions, outfit impression, and recognizable identity. She is an original AI digital human character, not a real person. Do not change her face, hairstyle, body type, outfit, or overall appearance. Female lead: The female lead has silver-gray short hair, a blue butterfly hair clip, a light gray athletic short-sleeve shirt, dark gray athletic short skirt-pants, and white sneakers. She stands across the ping pong table from the camera. She always holds the same ping pong racket in her right hand. Her left hand holds the yellow ping pong ball only before serving, then becomes empty after the serve. Her left hand must never hold a racket. POV character: The camera is a first-person POV. The opposite player is never fully visible. Only his right hand and forearm may appear at the bottom of the frame, holding one red ping pong racket. He always has only one red racket. Location: Ordinary indoor activity room with only one ping pong table. Simple walls, clean floor, realistic indoor recreational-room atmosphere. No crowd, no extra players, no extra tables. The camera faces the female lead across the table. The net is clearly visible. Camera: Single continuous handheld phone shot from first-person POV. Camera stays on the same side of the table. Use natural slight phone shake, small reaction movements, realistic focus adjustment, and physical body movement from playing. No cuts, no angle changes, no slow motion, no digital zoom. Keep the table, net, female lead, opposite player's red racket, and yellow ball readable during the rally. Ping pong physics rule: Only one yellow ping pong ball exists throughout the video. The ball must move continuously and physically. Every return must follow real ping pong rules: hit by one player, crosses over the net, bounces exactly once on the opponent's side, is immediately struck back. No double bounce, no net fail, no ball passing through the net, no floating, no teleporting, no clipping through racket, table, net, or body. Ball speed rule: The rally starts at moderate speed and gradually becomes faster. The ball should remain visible as a small fast yellow blur with readable trajectory. During normal rally shots, keep the ball fast but trackable. During the final smash, the ball becomes the fastest shot in the video, with stronger motion blur, a sharper downward angle, and a clear single bounce before a miss. Action timeline (0:00 to 15:00): The first-person POV faces the female lead across the ping pong table. She looks focused but playful, bounces the ball once, then serves. A smooth expert rally begins with forehands, backhands, and controlled push blocks, gradually speeding up. She becomes more competitive and playful, reading the returns. She turns sideways for a powerful forehand smash with physically correct mechanics: feet plant, hips rotate, torso follows, shoulder turns, arm swings through, racket contacts the ball. The smash sends the ball over the net at the highest speed of the video, landing once on the far side before shooting up fast. The opposite player swings late and misses by a clear small gap. The rally ends with the female lead leaning slightly forward, smiling with playful confidence, lightly raising the racket toward the camera in a teasing challenge gesture, and speaking one line before the video ends on her smiling face and raised racket. Audio: No music or subtitles. Use only realistic indoor room sound: ping pong ball bounce, racket hits, shoe squeaks, breathing, subtle phone-handling noise, a louder sharp smash hit near the end, and the female lead's single spoken line. Negative prompts: no duplicate ball, no extra balls, no ball teleportation, no floating ball, no ball clipping, no double bounce, no net fail, no ball passing through net, no impossible ball path, no ball stopping midair, no extra rackets, no duplicated racket, no racket switching hands, no extra ping pong table, no extra players, no camera cuts, no transition, no slow motion, no digital zoom, no subtitles, no watermark, no logo, no anime, no cartoon, no 3d render, no game-engine look, no identity drift, no hairstyle change, no outfit change, no broken anatomy, no frozen acting.
