About this skill
PDF to Video
将 PDF 文档转换为展示视频,自动提取核心观点并生成动态展示。
工作流程
digraph pdf_to_video {
rankdir=TB;
"接收 PDF 路径" -> "读取 PDF 内容";
"读取 PDF 内容" -> "分析提取核心观点";
"分析提取核心观点" -> "生成 props.json";
"生成 props.json" -> "复制 PDF 到 public";
"复制 PDF 到 public" -> "执行 remotion render";
"执行 remotion render" -> "输出 MP4 视频";
}
步骤详解
1. 读取 PDF 文件
使用 Read 工具读取用户提供的本地 PDF 文件路径。
2. 分析并提取核心观点
从 PDF 内容中识别:
- 标题:文档主标题,通常在首页
- 副标题:可选,如"核心内容概览"
- 核心观点:3-5 个关键页面及其标题
- 内容描述:每个关键页面的简要说明(1-2 句话),用于底部打字机效果展示
分析时关注:
- 章节标题和大纲
- 重点段落(加粗、高亮)
- 摘要和结论部分
- 图表和数据页面
3. 生成配置并渲染
目录结构:
props/ # 配置文件目录
glm45.json # 以文档名命名
report-2024.json
out/ # 输出视频目录
glm45.mp4
report-2024.mp4
public/ # 源 PDF 文件
document.pdf
创建 props/<name>.json:
{
"src": "/document.pdf",
"title": "文档标题",
"subtitle": "核心内容概览",
"highlights": [1, 3, 7, 12, 15],
"pageTitles": {
"1": "封面",
"3": "执行摘要",
"7": "市场分析"
},
"pageDescriptions": {
"1": "这是文档的封面页,展示了报告的主题和作者信息。",
"3": "执行摘要概述了报告的核心发现和建议。",
"7": "市场分析部分详细分析了当前市场趋势和竞争格局。"
}
}
执行命令:
# 复制 PDF 到 public 目录
cp /path/to/source.pdf ./public/document.pdf
# 写入配置到 props 目录(使用 Write 工具)
# 渲染视频(配置和输出使用相同命名)
npx remotion render PdfShowcase out/<name>.mp4 --props=./props/<name>.json
