AI Lip Sync

AI lip sync that survives
the close-up.

Upload a performance, pick a track, and the dialogue lands on the face. The Lip Sync Studio re-syncs any finished clip — a VisionX render or filmed footage — to new audio, so a campaign can change its script, or its language, without changing its face.

Why VisionX

Built for the shot, not the gimmick

Most lip-sync demos fall apart the moment the camera pushes in. This one lives inside a production pipeline — mouth-only by design, metered, and honest about what it is.

Dialogue that lands on the face

Pick a video and an audio track; the studio returns the clip with the mouth performance re-timed to the new dialogue. One job in, one synced performance out.

Generated or filmed

Works on VisionX-generated performances and uploaded footage alike — the spot you rendered last week and the one you shot last year take a new track the same way.

Localization without the reshoot

Dub the dialogue into one of 23 target languages in the Audio Studio, then sync the performance to the new track. Same face, new market.

The face doesn’t drift

Only the mouth performance is re-timed — the rest of the frame is untouched. The dialogue changes; the face, wardrobe, and grade do not.

A roster built to grow

The studio runs on Kling’s native lip-sync engine today, and the engine registry is built to add more lip-sync engines over time — same studio, same wallet, same Cast.

Costs quoted before you run

Lip-sync jobs are metered in VX through the same wallet as every render — billed at the Standard video-tier rate for the length of your audio track. 1 VX = $0.10 list.

How it works

New track to synced cut, four moves

Pick the performance

Upload the finished clip — a VisionX render or filmed footage. The shot is done; the dialogue is what changes.

Pick the track

Dub the original into one of 23 target languages in the Audio Studio, or bring your own audio — a new read, a revised claim, a cloned brand voice.

Sync

Kling’s native lip-sync re-times the mouth performance to the new track, metered in VX at the Standard video-tier rate for the audio’s length.

Ship the market

The synced clip flows back into the pipeline — approvals, delivery presets, review links — as the same campaign with a new script.

The killer workflow

Dub it, then sync it.

The cheapest spot to open a new market is the one you already approved. Dub the dialogue, sync the performance, and the campaign travels — no reshoot, no recast.

Included:Localize a hero spot — 23 target languages in the Audio Studio, one face across all of them.
Included:Swap the script after sign-off — re-voice a claim or a price without re-generating the shot.
Included:Keep one spokesperson in every market — only the mouth performance changes between cuts.
Included:Sync filmed material too — uploaded footage takes a new track the same way a render does.
Included:Finish per shot, inside the pipeline — synced clips route straight back to approvals and delivery.

FAQ

AI lip sync, answered

How does AI lip sync work on VisionX?

Pick a video and an audio track in the Lip Sync Studio, and it returns the clip with the mouth performance re-timed to the new dialogue. It runs on Kling’s native lip-sync engine today, and it works on VisionX-generated performances and uploaded footage alike.

Can I lip sync a video into another language?

Yes — that’s the workflow the studio was built around. Dub the spot into one of 23 target languages in the Audio Studio, then lip-sync the performance to the new track. Same face, new market, no reshoot.

Will lip sync change how my character looks?

No. Only the mouth performance is re-timed to the new track — the rest of the frame is untouched, so the face, wardrobe, and grade cannot drift. That’s what lets a localized cut read as the same campaign, not a remake.

How much does AI lip sync cost?

Lip-sync jobs are metered in VX through the same wallet as every render, billed at the Standard video-tier rate for the length of your audio track. 1 VX is $0.10 at list, and every account starts with a free 100 VX trial, no card required.

Which engines run the lip sync?

Kling’s native lip-sync engine runs the studio today, and the engine roster is built to add more lip-sync engines over time — the same multi-engine posture as the rest of the platform, with every job billing the same VX wallet.

Can I use VisionX lip sync for live avatars or meetings?

No — VisionX is a production pipeline, not a streaming product. Lip sync here is a per-shot finishing tool: it takes a finished clip and an audio track and returns a synced performance for the edit. There are no live avatars, webcams, or meeting integrations.
