My dad found the right car repair video on YouTube. English only. He speaks Russian and Romanian. Thirty minutes later he had the same video with a Russian voiceover in the original speaker's voice and Romanian subtitles. Next day he showed it to his mechanic. New video, the whole pipeline: https://www.youtube.com/watch?v=25D9QxH2NPw What I used, all free and running on my own computer: - Claude Code as the agent that ran everything - CapForge for the subtitles - Coqui XTTS v2 for the Russian voice clone, Piper as the native-voice fallback - faster-whisper to check every generated line - FFmpeg to mix it all The tools sheet with every link is attached to this post. Straight answer on cost: the tools are free. Claude Code needs a subscription or API key. Gemini TTS and ElevenLabs are optional and I did not need them. Straight answer on limits: it does not lip sync, and you need a CUDA GPU for the voice clone. Piper runs on anything.
