caption-burn 技能：将字幕烧录到 MP4 文件中，用于无声音频的短视频分发。
caption-burn 技能是一个专注于将字幕永久嵌入到 MP4 视频文件中的工具，特别适用于在静音模式下播放的短视频平台（如社交媒体上的自动播放视频）。该技能通过 FFmpeg 等命令行工具实现字幕烧录，支持 SRT、ASS 等多种字幕格式，并能自动调整字体、位置和样式以适应不同分辨率的视频。它通常集成在 AI 代理（如 Claude Code、Cursor）的工具链中，使开发者能够通过简单指令快速生成带有硬编码字幕的视频，无需手动操作复杂参数。该技能的核心优势在于自动化处理最终交付格式，确保字幕在所有播放环境中可见，从而提升 mute-feed 场景下的用户体验。
