Auto-dub Douyin/TikTok videos into any language using a fully local pipeline: download with Playwright Chromium + Douyin cookie → transcribe with Whisper → translate subtitles with the AI agent → generate TTS (gTTS / Edge TTS / ElevenLabs) → timing stretch with FFmpeg atempo → mix original audio at 10% + new TTS voice → burn ASS subtitle overlay (positioned over original sub area). Use when: (1) dubbing/translating a Douyin or TikTok video, (2) replacing original voice with translated TTS, (3) any "tải video douyin rồi dịch/lồng tiếng" request.
