Start a Lip Sync AI Job
A clear workflow from source video to reviewed result
Prepare one visible speaker and a clean audio track. Lip sync AI checks the video, estimates credits, and keeps every job state visible.
02
2. Add an authorized video
Choose a short video with one visible human speaker. Lip sync AI gets the clearest input from front-facing footage with even lighting and an uncovered mouth. This workflow does not promise talking photos, voice cloning, singing, or multiple-speaker selection.
03
3. Add the replacement audio
Upload the speech track that should drive the new mouth movement. Lip sync AI receives a more usable signal from clear speech than overlapping speakers, heavy music, or noisy recordings. Keep the audio duration close to the video duration.
04
4. Choose Basic or High Fidelity
Lip sync AI Basic is the lower-cost mode for short, clear, single-speaker clips and uses one credit per estimated output second. High Fidelity uses the more advanced model when facial and mouth detail matters more and uses nine credits per estimated output second.
05
5. Review the estimate and rights statement
Before lip sync AI starts, review the estimated output duration, selected generation mode, and estimated credits. Confirm that you have the rights and consents required for the video, likeness, voice, audio, and intended use before submitting.
06
6. Generate only after the safety check
Lip sync AI reserves the estimated credits when a job is submitted, then places the video in a safety-check state. Only a recorded PASS reaches the generation provider. REVIEW, REJECT, outage, or unknown results remain blocked, release the reserve, and consume no generation credits.
Why creators use Lip Sync AI
Built for authorized dubbing and editing
Three focused ways creators can use lip sync AI as part of a responsible video workflow.
Update spoken lines
Use lip sync AI to correct a product name, replace an outdated sentence, or test a different hook without filming the whole scene again. You remain responsible for the recording and for reviewing the altered result before publication.

Authorized demo
Prepare localized versions
Use lip sync AI with a translated voice track when the team has permission to edit the performance. Keep the source clip simple during initial testing, and do not present the result as an unaltered statement by the speaker.

Localized demo
Test AI-character dialogue
Use lip sync AI to try a new audio performance on existing video of an authorized synthetic character. Results may differ for stylized faces, exaggerated motion, rapid cuts, and nonhuman features.

Synthetic character
Visual Calibration GuideRecommended
✓ Front-facing, clear light
✕ Harder input
✕ Harder input
Keep the mouth clearly visible, the frame stable, and the replacement speech clean. Profiles, obstruction, and rapid motion make a first test less reliable.
Prepare a strong first test
What makes a better input
Lip sync AI has to identify and follow a visible face over time. A short shot with one speaker, stable lighting, and a readable mouth is a more appropriate first test than a montage with multiple faces.
One clearly visible human speaker, reasonably large in the frame
Stable lighting, steady framing, and limited blur or obstruction
Clean replacement speech with limited music, echo, or background noise
Rights and consent confirmed before upload
Inputs that may be harder
Multiple speakers, profile views, covered mouths, rapid cuts, extreme head movement, overlapping dialogue, strong background music, singing, and nonhuman faces are not promised in the initial product.
Basic and High Fidelity Explained
Choose the generation mode that fits your clip
Both lip sync AI modes require production validation. Neither is a promise that every face, angle, edit, or recording will succeed.

Credits before buzzwords
Compare expected use across subscriptions and packs
Lip sync AI uses credits so you can compare expected use across subscriptions and one-time packs. Basic estimates one credit per output second, while High Fidelity estimates nine. This ratio reflects the current cost model, not a quality guarantee.

OUTAGE
The service is drafted for users age 18 or older. Sexualized or exploitative content involving a minor is prohibited.
A safety check, rights statement, reporting process, and account enforcement work together; none transfers legal responsibility from the user.
What happens after submission
From safety check to reviewed result
Lip sync AI reserves the estimate when a job is submitted. After a PASS, lip sync AI sends the job to the generation queue. A blocked safety check releases the reserve, while processing time depends on input duration, mode, provider demand, and technical conditions.
Stage 1
1. Queued and processing
The lip sync AI job page shows queued and processing states while the provider works. There is no fixed speed promise in the current product contract.
QUEUED → PROCESSING
Stage 2
2. Success and review
If lip sync AI generation succeeds, the job page shows an authenticated preview and download action. Review the entire video for artifacts, timing issues, unwanted changes, and rights or disclosure requirements before publishing.
SUCCESS → REVIEW → DOWNLOAD
Stage 3
3. Failure and credits
If a covered lip sync AI provider failure produces no usable output, the ledger releases the reserved generation credits. User cancellation, unsuitable sources, or subjective dissatisfaction may follow different rules.
FAILURE → CREDIT LEDGER CHECK
