Generate a 30-second realistic livestream-style video. Scene: Selfie/webcam-style footage of a female content creator sitting at her desk during a YouTube-style livestream. The camera is fixed like a webcam at eye level, slightly wide, showing her from the waist up. She is in a cozy creator room with a desk setup, soft LED lights, monitor glow, microphone arm, keyboard, mouse, headphones, small decor items, and a warm realistic background. Main character: A young adult female creator, friendly and expressive, natural makeup, casual stylish outfit, soft natural skin texture, relaxed posture. She looks directly into the webcam, occasionally glances at the chat panel on her screen, smiles, laughs softly, and speaks casually to viewers. Keep her face, hairstyle, outfit, and body proportions consistent throughout the entire video. Livestream interface: A realistic YouTube-style livestream layout surrounds the camera feed. Include a clean video frame, live badge, viewer count, like button area, subtle progress bar, and a visible chat panel on the right side. The chat messages scroll slowly upward. The interface should feel authentic but use fictional usernames and generic readable short comments. No real YouTube logo, no copyrighted branding, no actual creator name. Video style: Realistic webcam footage, slight compression, subtle autofocus, natural screen glow on her face, soft room lighting, minor webcam noise, realistic livestream latency feeling. The video should feel like a real creator casually chatting live with her audience. Timeline: 0–5s: The creator looks into the webcam and smiles warmly. She adjusts her posture slightly, rests one hand near the keyboard, and says hello to the stream. Chat messages begin scrolling slowly beside her. 5–10s: She glances to the chat panel, reads a comment silently for a second, then laughs softly. She points lightly toward the screen and responds casually, as if answering a viewer question. 10–15s: She leans a little closer to the webcam, speaking with friendly energy. The monitor glow shifts subtly across her face. Her hand gestures are small and natural. 15–20s: She looks down at the desk, takes a quick sip from a mug or water bottle, then looks back up. The chat continues moving slowly with friendly messages and emojis-style reactions, but no distracting large text. 20–25s: She reads another comment, smiles wider, nods, and gives a thoughtful answer. Her expression feels genuine and relaxed, like a familiar livestream moment. 25–30s: She waves briefly at the camera, says something cheerful to viewers, then settles back into her chair while still smiling. The livestream interface remains visible and stable. Camera: Fixed webcam angle, eye-level, slight wide-angle lens, minimal movement. No cinematic camera moves, no cuts, no zooms. Keep the livestream layout stable and readable. Audio direction: Natural room tone, soft voice, subtle keyboard taps, quiet chair movement, no background music unless very faint and ambient. Avoid: No real platform logos, no real usernames, no copyrighted UI, no distorted hands, no warped face, no duplicated person, no extra people, no unreadable chaotic text, no heavy beauty filter, no subtitles, no watermark, no black borders.
