Seedance 2.5 女孩拍摄街头vlog UGC口播提示词

15-second UGC street vlog, shot on an early 2010 smartphone, front camera selfie style, like an old iPhone 4 / Android video upload. Same young East Asian girl (Korean-Chinese look, early 20s, long black hair with side-swept bangs, light pink lip tint, oversized cardigan over a graphic tee, small shoulder bag) walks through a busy city street holding the phone at arm's length, filming herself. Low-resolution 480p look, grainy front-camera quality, washed-out colors, slightly overexposed daylight, soft digital noise, heavy compression artifacts, rolling shutter wobble, auto-exposure shifting when she turns. Background: small shops, neon signs, bicycles, people walking past, street food stall, vending machines, crosswalk. 0-2s: She walks toward the phone smiling and says "Hi guys! Today I'm exploring the street~" while the frame bobs with her steps. 2-4.5s: She flips to the back camera, quick shaky pan across shops and neon signs, then flips back to her face, laughing. 4.5-7s: She stops at a street food stall, holds up a snack close to the lens, takes a bite, wide eyes, thumbs up. 7-9.5s: She walks to a vending machine, buys a canned drink, shows it to the camera and says "Omg so cute!", then cracks it open. 9.5-12s: She crosses the street at a crosswalk while a bicycle passes behind her, the camera shaking, she looks back at it and giggles. 12-15s: She turns into a small accessory shop window, tries on a funny hat, makes a peace sign, waves, says "Okay bye guys, see you next time!" and her thumb reaches to the screen to stop recording, cut to black. Audio: street ambience, distant traffic, tinny phone mic, wind noise, slight audio clipping when she laughs, can opening sound, faint lo-fi 2010 indie pop from a nearby shop. Voice casual, cheerful, a bit muffled. Style: nostalgic 2010 phone vlog, amateur, authentic, quick handheld cuts between scenes, no cinematic lighting, no stabilization, no color grading.
