教室里的吉他弹唱 `AI 反推`

Duration: 15 seconds | Aspect ratio: 9:16 | Style: Photorealistic, casual lifestyle portrait SCENE Young woman with long ash-blonde hair and straight bangs. She wears a white long-sleeve button-up shirt, grey plaid pleated skirt, white knee-high socks, a silver necklace, and a dark beaded bracelet. She sits on a wooden chair holding a light wood acoustic guitar with a dark pickguard. The setting is a music classroom featuring a green chalkboard, scattered black music stands, a black upright piano, a wooden floor, and a large left-side window showing city buildings. SHOT BREAKDOWN 0-4s — Medium-full shot framing the woman from the knees up. She sits centered, strumming the guitar, and looks directly at the camera with a gentle smile. 4-8s — She subtly shifts her posture while playing. Her left hand adjusts chords on the fretboard while her right hand continuously strums. 8-12s — Her lips move clearly as she sings along to the music. She maintains steady eye contact and a bright expression. 12-15s — The performance continues seamlessly. She smiles, holding the guitar comfortably, maintaining a relaxed seating position as the video concludes. CAMERA Static medium-full shot. Eye-level angle. Steady framing with no camera movement or cuts. Natural depth of field keeps the background classroom elements recognizable but slightly soft. LIGHTING & PALETTE Soft, diffused natural daylight enters from the left window, evenly illuminating her face. Warm interior atmosphere. The palette features crisp white, ash blonde, light oak wood, slate grey, and contrasting black accents. AUDIO Bright acoustic guitar strumming, clear female singing vocals matching the lip movements, subtle room reverberation. AVOID Camera movement, quick cuts, heavy shadows, distorted fingers, electric guitars.
