1. Language Standards

Core Rules

Dialog language must be consistent — avoid mixing Chinese and English (except for proper nouns).

#### Correct Examples

{The weather is nice today}  ✓
{How are you}   ✓  (English can be used in English-language scenes)

#### Incorrect Examples

{The weather is nice today, you know}  ✗  (Mixing Chinese and English)

Non-English Dialog Scenarios

If the dialog is in a non-English language (neither Chinese nor English), specify the language.

#### Examples

Said in Japanese: {こんにちは}
Said in Korean: {안녕하세요}

3. Advanced Prompt Formula Guide

Core Concept

Seedance 2.0 is essentially a multimodal AI director: it reads your text prompt, images, video, and audio simultaneously, and internally decomposes them into the "spatial layer" (what's in the frame) and the "temporal layer" (how things change over time) to understand and generate visuals.

Therefore, a good prompt is not just "copywriting-style description" but rather "engineering-style instructions."

Writing Process

• Identify "who" is doing "what" → Define subject + action description
• Set "where" and "what atmosphere" → Scene environment + lighting & color
• Tell the model "how to shoot" → Camera movement
• Refine the result → Style + quality + constraints

Summary in One Sentence

First identify who is doing what, then set where and what atmosphere, then tell the model how to shoot, and finally refine the result with style, quality, and constraints.
