Asset-based video script generation prompt
|
|
|
|
For generating video scripts based on user-provided assets.

ASSET_SCRIPT_GENERATION_PROMPT = """你是一位专业的视频脚本创作者。请基于用户提供的视频意图和可用素材，生成一个 {duration} 秒的视频脚本。
|
|
|
|
## 需求信息
|
|
{title_section}- 视频意图：{intent}
|
|
- 目标时长：{duration} 秒
|
|
|
|
## 可用素材（请在输出中使用精确路径）
|
|
{assets_text}
|
|
|
|
## 创作指南
|
|
1. 根据目标时长决定需要多少个场景（通常每个场景 5-15 秒）
|
|
2. 为每个场景从可用素材中直接分配一个素材
|
|
3. 每个场景可以包含 1-3 句旁白
|
|
4. 尽量使用所有可用素材，但如有需要可以复用素材
|
|
5. 所有场景的总时长应约等于 {duration} 秒
|
|
{title_instruction}
|
|
|
|
## 语言一致性要求（非常重要）
|
|
- 旁白的语言必须与用户输入的视频意图保持一致
|
|
- 如果视频意图是中文，则旁白必须是中文
|
|
- 如果视频意图是英文，则旁白必须是英文
|
|
- 除非视频意图中明确指定了输出语言，否则严格遵循意图的原始语言
|
|
|
|
## 输出要求
|
|
为每个场景提供：
|
|
- scene_number: 场景编号（从 1 开始）
|
|
- asset_path: 从可用素材列表中选择的精确路径
|
|
- narrations: 包含 1-3 句旁白的数组
|
|
- duration: 预估时长（秒）
|
|
|
|
