VideoDubbing.online is a free AI-powered platform for professional video dubbing, subtitling and voice-over generation. Upload your video or paste a YouTube/Facebook URL and get automatic transcription, translation and dubbing in multiple languages.
We support most common video formats (MP4, AVI, MKV, MOV, WebM) and audio formats (MP3, WAV, OGG, FLAC). You can also process YouTube and Facebook video URLs directly.
Our AI pipeline uses OpenAI Whisper for speech recognition, LibreTranslate for text translation, and Google TTS for voice synthesis. The process: 1) Extract audio, 2) Transcribe speech to text, 3) Translate to target language, 4) Generate voice-over, 5) Mix with original video.
