Video-to-Text 视频转文字

把视频变成可复制、可搜索的文字。支持抖音分享链接(元数据,无需登录)和本地视频文件(语音转写)。

触发条件

用户发送以下内容时使用本技能:

  • 抖音分享链接,要求"转文字""提取文案""拆解视频"
  • 本地视频文件(.mp4/.mov),要求"语音转文字""字幕"

使用步骤

1. 抖音分享链接 → 元数据

python3 scripts/vtt.py "https://v.douyin.com/xxxx/"
  • 输出元数据(标题/作者/点赞/标签)
  • 注意:分享链接当前只提取元数据——语音转写请让用户保存视频后走本地文件(步骤 2)

2. 本地视频文件 → 语音转写

python3 scripts/vtt.py 本地视频.mp4
  • 自动提取音频、faster-whisper 转写(中文)
  • 转写文本保存为 <输入名>_transcript.txt 并打印时间戳分段

依赖(首次使用时安装)

pip3 install faster-whisper        # 转写需要(首次会下载 tiny 模型 ~75MB)
# macOS 自带 avconvert;Linux 需 ffmpeg
# 抖音 SSR 解析零依赖(curl + 标准库)

已知陷阱

  • duration_ms=0 假阴性:SSR 元数据时长可能为 0,但实际是视频。若元数据显示 0 秒且有下载 URL,先下载验证,不要直接判定为图文。
  • play_addr URL 过期:SSR 解析出的视频 URL 可能 404,此时需 Cookie 降级或让用户提供文件。
  • whisper 转写慢:Intel Mac 上 3 分钟视频约 5 分钟;转写必须加 language='zh' 否则自动检测多花 1-2 分钟。
  • 图文内容:duration=0 且下载文件 <1MB 时是图文(无音频),只输出元数据,不要编造内容。

Teaches when to recall from long-term memory before acting and when to save durable decisions, corrections and failures afterwards. Use when a memory tool or MCP memory server is connected but the agent is not using it consistently, when the user complains that the assistant forgets preferences, conventions or past decisions between sessions, or when setting up persistent memory for a project. Works with any memory backend: a folder of Markdown files, a local MCP server, or a managed service.

Checks which private files (.env, keys, secrets) Claude Code and its subagents reached in this project, whether a value came into an agent's context, and which key to change, by running the open source agentwhy CLI over the session records Claude Code already keeps on disk. Use when the user asks whether the agent or a subagent read their .env or other secrets, which private files a session touched, whether a key leaked into the conversation, or which key to rotate. Runs locally and never prints a secret value.
