Prompt and Parameter Best Practices

I. Prompt Structure (Text-to-Video)

• Narrative Goal: The "emotion/information" you want to convey (e.g., warm-textured unboxing demo).
• Subject and Scene: Subject appearance, props, lighting, time and weather, shot type (close-up/medium/wide).
• Camera Language: Camera movement (push in / pull out / pan / tilt / orbit), pace (slow/medium/fast), depth of field.
• Texture Modifiers: Realistic/cyber/film grain/high contrast/natural light; resolution and duration.

II. Image-to-Video

• Choose high-resolution, clear subject images; emphasize "maintain subject consistency + desired camera movement" in descriptions.
• For lip-sync needs, prepare lip-sync copy and audio materials for system audio-visual alignment.

III. Resolution/Duration/Speed Trade-offs

• Need faster output: Choose Fast;
• Need better stability: Choose regular T2V / I2V;
• Mobile-first platforms: 720p is more stable; need higher clarity or secondary editing: choose 1080p.
