Seedance 2.0Expression transition from cold to shy smile, slow and natural, 8 seconds. Start: The young woman sits courtside, poker-faced, cold and aloof expression, staring straight ahead, completely unaware of the camera. No smile, very calm. Middle: She slowly turns her head toward the camera. Her eyes shift softly. Her facial expression begins to soften. End: She notices the camera. Her cold expression breaks into a shy, subtle, gentle smile. Lips slightly parted. A natural blush appears on her cheeks. She makes brief eye contact with the camera, then looks down shyly before glancing back up with a soft smile. Camera: Static broadcast camera, slight depth of field, ESPN live TV texture. Style: Ultra-realistic, natural skin texture, authentic human micro-expressions, organic facial muscle movement, no AI smoothing, no morphing, no flickering, no distortion. Live arena lighting, broadcast color grading, subtle compression artifacts. 16:9. Negative prompt: Exaggerated smile, laughing, open mouth wide, crying, anger, robotic movement, CGI, cartoon, overacting, unnatural blinking, face swapping, glitching.
Seedance 2.015s, cinematic emotional confrontation. Two characters @[chracter sheet ref] stand face-to-face inside a small apartment kitchen late at night. The room is dimly lit by a single warm overhead light and soft city lights leaking through the window. The atmosphere feels emotionally exhausted, tense and painfully intimate, like an argument that has been building for years. Modern cinematic realism, subtle handheld camera movement, shallow depth of field, soft film grain, emotionally restrained acting, realistic silence between dialogue lines. Beat 1: The emotional state remains at high arousal and medium-low valence. Camera: slow handheld side shot circling both characters tight over-the-shoulder close-ups brief eye-level two-shot showing emotional distance FACS Character A: AU4 + AU7 + AU17 Dialogue A: /juː ˈnev.ɚ ˈriː.ə .li lʊkt æt miː/ /juː wɚ ɔːlˌweɪz ˈsʌmˌwɛɹ ɛls/ Voice: tight restrained voice, controlled anger, uneven breathing Character A tries to stay calm while suppressing years of resentment. Beat 2: The emotional state gradually shifts toward very low valence and medium-high arousal. Camera: slow push-in toward Character B extreme close-up on trembling eyes and mouth wide static shot showing silence after the argument peaks FACS Character B: AU1 + AU4 + AU15 + AU25 Dialogue B: /aɪ wəz ˈtɹaɪ.ɪŋ maɪ bɛst/ /aɪ dɪdnt noʊ haʊ tə fɪks ˈɛv.ɹiˌθɪŋ/ Voice: breaking voice, unstable breath support, emotionally collapsing delivery Beat 3: The emotional state remains at very low valence and medium-low arousal. Camera: locked wide shot with silence between them slow close-up on both characters avoiding eye contact subtle rack focus between faces FACS Character A: AU1 + AU15 + AU17 Dialogue A: /ˈmeɪ.bi wiː stɑpt ˈlɪs.ən.ɪŋ ə lɔŋ taɪm əˈgoʊ/ Voice: emotionally exhausted, quieter delivery, fading anger replaced by sadness No exaggerated screaming, no violence, no comedy, no text overlay, no watermark.
Seedance 2.0Use the storyboard reference @[storyboard ref] as the complete visual and choreography source for a 15-second video. Follow all 12 beats sequentially from left to right, top to bottom. Do not reinterpret the actions, poses, camera angles or emotional progression. Preserve the storyboard’s shot order, movement logic, framing variety and final pose. Compress the full 12-beat sequence into 15 seconds. Each beat must appear clearly as a fast motion snapshot, not as a full-length action. Use urgent rhythm, quick cuts, match cuts and whip transitions. No pauses until the final beat. Keep the same single female performer @[character ref] identity from the character reference. Do not duplicate her. Continuous live singing throughout, with visible breath, mouth movement, body strain, fabric motion, floor contact and emotional escalation. Environment: massive empty brutalist hall, wet reflective floor, smoke, harsh light beams, minimal space. Cinematic arthouse camera energy: handheld movement, close-ups, overhead flashes, low angles, orbit motion and extreme negative space. Final beat holds for the last 1 seconds under one harsh isolated spotlight. Lyrics only once, IPA: /aɪ muːv θruː ˈsaɪləns/ /ðə laɪt breɪks miː/ FACS: AU1+AU4 tension, AU5 intensity, AU25 singing mouth, AU26 open release, AU43 exhausted blink. No text, no annotations, no timestamps, no watermark.
