Swap the audio on any video: Match the lips with emotion and style transferred automatically
Reshooting a video just to change a hook, fix one line, or record a translation is slow and expensive, and it does not scale when you are building automated pipelines. Lip Sync 2.0 fixes that. Send the API a video and a new audio track, and it returns a fully lip-synced result that matches the original take.
Built on VEED's most capable lip sync model to date, the API transfers emotion, style, and timing from your new audio automatically, with no per-subject training or fine-tuning. Use it to change ad hooks, fix audio mistakes, or localize content into any language, all through one video API.
How to lip sync a video with the Lip Sync 2.0 API:
Step 01
Send your video and audio
Make a request with your source video and the new audio track. The API accepts standard video and audio files, subjects up to 4K, clips up to 10 minutes, and files up to 5GB. No training data or reference footage needed.
Step 02
Let the model sync and transfer
The model detects the face and re-renders the mouth to match your new audio. Emotion and speaking style carry over from the audio, and you control the sync strength. Results come back faster than any manual retakes.
Step 03
Get your lip-synced video back
The API returns a finished video with the face synced to the new audio, at the same resolution you sent in. Pair it with translated voiceovers from VEED's AI video translator to ship localized versions at scale.

Change the audio, keep the performance
One take becomes endless versions. Swap in a new hook to A/B test an ad, drop in a corrected line, or replace the voiceover with a translation, and the lips match every time. No reshoot, no re-record, no manual animation. The original visual take stays intact while the audio does the work.
Dubbing that looks like the real take, not AI
Lip Sync 2.0 transfers emotion and speaking style straight from your audio, so the result reads as the speaker's own performance rather than a generic AI overlay. Editable sync strength lets you control how tightly the mouth tracks the audio, giving your team broadcast-quality output you can put a brand name behind.
Built for pipelines and scale
Call it over a REST API or run it as a Fal deployment, and process footage up to 4K and 10 minutes at $0.07/sec regardless of resolution. "Zero-shot" means no per-face setup, so you can batch thousands of clips. Combine it with VEED's Fabric 1.0 API for talking-video generation or the Subtitles API to caption every localized version.
FAQ
The Lip Sync 2.0 API is a video-to-video dubbing endpoint built on VEED's most capable lip sync model. You send it a video and a new audio track, and it re-renders the speaker's mouth to match the audio, transferring emotion and style from the recording. It is zero-shot, so no per-subject training or fine-tuning is required, and it returns a finished video in seconds.
VEED's original lip sync API is the affordable, entry-level option at $0.40/min for straightforward lip remapping. Lip Sync 2.0 is the production-grade tier: it adds emotion and style transfer, controllable sync strength, support for clips up to 10 minutes and 4K, and a jump in visual quality. Choose 2.0 when you need dubbing that holds up to close viewing.
The Lip Sync 2.0 API costs $0.07 per second of video processed, and the price is the same at every resolution, so a one-minute clip costs $4.20 whether it is 720p or 4K. There is no per-subject training fee and no fine-tuning step. You send video and audio, and you pay only for the seconds you process.
No. Lip Sync 2.0 is zero-shot, so it works on any new face the first time without training data, reference clips, or a setup step. Send a video and an audio track, and the model handles the sync directly. This makes it practical for automated pipelines where you process many different speakers and cannot train a model for each one.
The API takes a video file plus a separate audio file. It supports resolutions up to 4K, clips up to 10 minutes long, and files up to 5GB, and the $0.07/sec price does not change with resolution. It returns a video at the same resolution you sent in, with the speaker's mouth synced to the new audio and their emotion and timing preserved.
The model delivers its highest fidelity on a single, forward-facing human speaker, and it also handles side-angle subjects up to a medium closeup. It currently supports one active speaker per scene and does not support non-human subjects. For localization and dubbing, pair it with translated audio to create market-ready versions without reshooting the original video.
