Change a hook, fix a line, or localize every video
Reshooting a finished video just to update one opening line, repair a stumble, or record another language is slow, costly, and difficult to automate. Vidione’s Lip Sync 2.0 API replaces that entire loop. Send one source video and a new audio track, then receive a finished result that preserves the original take while matching the new delivery.
Built to retain emotion, timing, and speaking style, the model works without subject-specific training or fine-tuning. Growth teams can test multiple hooks, product teams can fix approved footage, and localization teams can create market-ready versions from one shoot. It works alongside the rest of Vidione’s video creation tools.
How to lip sync a video with the Lip Sync 2.0 API:
Step 02
Let the model match the performance
The model finds the face and rebuilds the mouth and lower face around the new recording. Emotion and speaking style carry through, so the result still feels like the speaker’s own performance.
Step 03
Receive your lip-synced video
Get a finished video back at the resolution you sent, with the mouth aligned to the new audio. Pair it with translated voiceovers to publish localized versions at scale.

New audio, same on-camera performance
Turn one finished take into many versions. Test a new hook, patch a corrected sentence, or replace the voiceover with a translation while the original visuals stay intact. No reshoot, re-recording, or manual mouth animation is needed for social cuts, short-form clips, or a full channel upload.
Dubbing that feels like the original take
Emotion and speaking style travel with the new audio, so the result reads as the speaker’s own delivery instead of a pasted-on track. The system is designed for difficult footage too: hands crossing the face, low light, quick camera movement, multiple angles, and close-up mouth detail. The final output is polished enough to publish under your name.
Ready for pipelines and scale
Call the endpoint over REST or deploy it in a serverless workflow. Process footage up to 4K and 10 minutes at a consistent rate of $0.07 per second, regardless of resolution. Zero-shot processing means no face-by-face setup, so teams can batch thousands of clips across different speakers, animated subjects, and non-human characters. Combine lip sync with image-to-video generation, captions, translation, and brand finishing in one workflow.
FAQ
It is a video-to-video endpoint that rebuilds a speaker’s mouth to match a new audio track. Send a source video and a separate recording, then receive a finished video aligned to the new performance. Vidione’s Lip Sync 2.0 model also carries over emotion and speaking style, so the result feels naturally performed.

More than lip sync
Lip Sync 2.0 is one part of Vidione’s broader AI video creation platform. Generate talking visuals from a single image with MotionFrame, create presenters with AI avatars, then refine the result: trim it, caption it, translate it, and apply your brand system so every version feels made by your team rather than by a machine. From the first generation through dubbing, branding, and export, Vidione turns one video into every version you need in minutes.
