Redub video audio online with VoxCraft. Keep the original picture and replace the spoken track: extract audio, transcribe, translate, re-voice with a neural voice, then mux back onto the video — without needing a cloned voice or any special hardware.
This is the practical path for creators who want an Urdu, Hindi, Tamil, or English version of an existing clip without re-recording. Phase 1 uses the same neural voices as Studio; voice-cloning the original speaker may follow once voice cloning launches (coming soon).
How it works
- Upload an MP4/MOV/WebM/MKV (up to 50MB, up to ~10 minutes).
- Choose the source language for transcription (or leave Auto).
- Pick the target language and any of the 130+ stock voices — same picker as Studio.
- VoxCraft transcribes, translates with Google NMT, generates the new voice with edge-tts, and muxes it onto your video.
- Download the dubbed MP4, or just the new audio track if you prefer to re-mux yourself.

Tips for better results
- Clear speech transcribes better than music-heavy or noisy tracks — denoise first if needed.
- If source and target are the same language, translation is skipped and only the voice is replaced.
- Match the target voice's language to the target language for natural pronunciation.
- Long videos burn TTS character quota the same way Studio does — a 5-minute script is typically a few thousand characters.
Frequently asked questions
Is this free?
No — redub is included with the Pro plan. Free accounts can still use Transcribe and Extract audio separately.
Does it clone the original speaker?
Not in Phase 1. It uses the same stock neural voices as Studio (130+ voices, 40+ languages). Cloned-speaker redub may follow once voice cloning launches (coming soon).
Which languages work?
Any language pair where we have a stock voice and Google Translate coverage — including Urdu, Hindi, Bengali, Punjabi, Tamil, Telugu, Arabic, and English variants.
What happens to the original audio?
It is replaced. Download the separate audio track if you want both.
How long can a video be?
Up to about 10 minutes and 50MB in Phase 1.
