YouTube Chinese Localizer

What it does

This skill automates turning a YouTube URL or local video into a Chinese-localized deliverable. It covers downloading or ingesting the source, timestamped transcription, natural Simplified Chinese translation, Mandarin TTS dubbing, optional audio mixing, and final MP4 export with burned-in or sidecar subtitles.

When to use it

Use when you need repeatable localization for videos: creating Chinese subtitles, producing a Mandarin dub, or exporting a final localized video for distribution. It's useful for content repurposing, translation workflows, and batch localization jobs.

What's included

• Scripts: pipeline wrapper (scripts/run_localize_video.sh) and core pipeline (scripts/localize_video.py).
• References: runtime requirements and troubleshooting (references/runtime-requirements.md).
• Instructions: step-by-step run examples, decision rules for transcription and download order, and failure handling for missing tools or credentials.

Compatible agents

Agents that can run shell scripts and manage long-running processes (Claude Code, CLI-enabled assistants). The pipeline expects ffmpeg, yt-dlp (for online sources), and optional faster-whisper and Volcengine credentials for full functionality.
