Generate lip-synced videos at scale with our lip sync AI API
VEED's lip sync API remaps speaker lips to match new audio perfectly. No training required, no minimum input length. Upload an existing video, provide replacement audio, and get back an MP4 with synchronized lip movements — video in, video out. Fast processing, affordable pricing at $0.40/min, and developer-ready with just two inputs: video and audio.
The lip sync API automates many video workflows. Submit multiple requests to dub keynote speeches into different languages. Rephrase video ads to refresh outdated product details without reshooting. Build AI customer service agents that respond with personalized video. This AI lip sync API processes videos while keeping users on your platform. Get API access on fal.ai.
How to use the lip sync API:
Step 01
Provide video and audio input
Upload your source video and replacement audio. The API accepts standard video formats (MP4, MOV, WebM, M4V) and audio formats (MP3, OGG, WAV, M4A, AAC). Works with any aspect ratio.
Step 02
Process and sync
Submit your API request. The lip sync API analyzes facial movements and remaps lip positions to match your new audio track. The AI handles natural mouth shapes, speech timing, and facial dynamics automatically—no manual animation or complex configuration required.
Step 03
Receive your synced video
The API returns an MP4 video URL with synchronized lip movements. The speaker appears to naturally say the new audio, maintaining authentic facial expressions and head movements throughout.

Fast processing built for high-volume workflows
The lip sync API processes videos at around 2-2.5 minutes per video minute. It handles videos up to 5 minutes long through a queue system where you submit requests and receive processed videos back. Submit multiple requests to process videos for different languages or versions.
Affordable per-minute pricing
VEED's lip sync API costs $0.40 per minute of video processed. Get transparent pricing with no hidden fees. A 5-minute video costs $2.00. You know exactly what you'll pay before you process anything. Traditional professional dubbing services can cost hundreds or thousands per video for the same localization work.
Developer-ready API integration
Start with just two parameters: video_url and audio_url. No training required, no minimum input length to worry about. The API accepts standard video and audio formats, works with any aspect ratio, and returns an MP4 URL ready to use. Process vertical social content, horizontal demos, or square format videos—the lip sync API handles them all.
