Repurposing YouTube content for Bilibili expands reach into the Chinese market without manual video re-encoding or subtitle translation work.

A Claude Code skill that repurposes YouTube videos for Bilibili with bilingual (EN/ZH) hardcoded subtitles. The pipeline downloads with yt-dlp, transcribes with Whisper, validates and fixes subtitle timing, AI-translates to Chinese, merges bilingual subtitles, burns them in with ffmpeg (Netflix-style presets), and generates publish info. Invoke with /yt2bb <YouTube URL>.
