Seedance 2.5 Kim 对镜头挥手 复古提示词

[Generation goal] Reference-to-video. One continuous 20-second handheld camcorder montage following a High school student named Kim through four locations, shot to look like 1998 consumer VHS home video. [Reference roles] @Image 1 defines Kim: East Asian woman, late teens, black shoulder-length waves, open red and white plaid flannel over a white ribbed tank, light-wash straight-leg jeans, white chunky sneakers, thin gold chain. Use her face, hair and wardrobe only. Do not inherit the gray studio backdrop, the four-panel layout, the corner inset, or the neutral expression. [Stage 1 — approximately 0-5s] The operator walks through a doorway into a school class room of seated students. Kim sits turned sideways in her chair mid-conversation with one classmate. She catches the lens, breaks off the sentence, opens into a wide open-mouth smile and waves with her whole hand. No backpack anywhere on her. End state: Kim still waving, the classmate turning toward the camera. [Stage 2 — approximately 5-10s] High school corridor. Lockers line both sides. Kim steps into the middle of the hall and drops into a four-count hip hop step: shoulder rolls, a quick two-step, one spin. She loses the beat coming out of the spin, laughs at herself, and keeps going anyway. Two students edge past along the wall. End state: Kim doubled over, hands on her knees, laughing. [Stage 3 — approximately 10-15s] School cafeteria. Kim at a long table with three friends, tray in front of her, black backpack on the floor beside her chair. She says something, the table laughs, she points at one friend. End state: Kim leaning back in her chair, grinning. [Stage 4 — approximately 15-20s] Outside, brick building of the high school behind her. Kim works a piece of gum and blows a pink bubble that grows past her chin. At 18s a friend's finger enters from frame left and pops it. Gum flattens across her lips, cheek and nose. Half a beat of stillness, then both fold into laughing. End state: Kim peeling gum off her cheek, still laughing. [Camera] Handheld throughout, operator walking, eye level to chest height. Each location change is a hard in-camera cut with one frame of motion blur and a tape glitch. [Visual style] 1998 consumer camcorder recorded to VHS. Soft focus, visible horizontal field lines, chroma bleed and smear on the red plaid, white dropout streaks, windows blown out by auto-exposure, heavy gain grain indoors, cool fluorescent inside and warm daylight outside. [Audio] (thin hip hop track from a boombox down the corridor, stage 2 only) <room chatter, footsteps on tile, tray clatter, wind on the mic outside> American English, casual and unrehearsed, spoken by Kim in stage 1: {Are you recording? Oh my god.} Camcorder mic character: mono, thin, slightly clipped. [Maintain consistency] One Kim throughout, same face, hair and outfit in all four locations. No backpack on her body in any stage; it appears only on t
