What is AI video dubbing?
AI video dubbing is the process of automatically translating and re-recording a video's audio in another language using artificial intelligence. Unlike traditional dubbing that requires voice actors and studio time, AI dubbing uses voice cloning technology to replicate the original speaker's voice in the target language — preserving their tone, emotion, and speaking style.
DubSync combines three AI technologies: neural machine translation for accurate script conversion, voice cloning to maintain speaker identity across languages, and lip synchronization to match mouth movements with the new audio. The result is a dubbed video that looks and sounds natural in any language.
How DubSync works
DubSync uses AI to automate the entire video dubbing workflow — from transcription to voice cloning to lip sync — in three simple steps.
Step 1
Upload your video
Upload any video file (MP4, MOV, AVI up to 5GB). DubSync automatically transcribes the original audio and detects the source language.
Step 2
AI processes your video
Our AI translates the transcript, clones the speaker’s voice in the target language, and generates lip-synced audio that matches mouth movements. The entire process takes 2–5 minutes for a typical 10-minute video.
Step 3
Download your dubbed video
Review the result, make any edits to the translation, and download your dubbed video in up to 4K quality. Share it with your global audience instantly.

Frequently asked questions
DubSync uses AI to analyze the speaker's voice characteristics — pitch, tone, accent, and emotion — from the original video. It then generates new speech in the target language that preserves these characteristics, so the dubbed version sounds like the same person speaking a different language.
DubSync supports MP4, MOV, AVI, WebM, and MKV formats. The maximum file size depends on your plan: 100MB for Free, 500MB for Starter, 2GB for Pro, and 5GB for Enterprise.
