Jinova Compute · Lip Sync Video

Make your video speak your audio.

Upload a video and an audio track. Jinova Compute matches the speaker's mouth to your audio and gives you a lip-synced video, ready to download.

You supply both files. Jinova does not write, voice or translate the speech.

Real output

One run of the live workload

A silent 4K clip and a separate voice track went in. This came back.

Transcript“Upload your video and audio, then let Jinova Compute create a naturally lip-synced result, ready to download.”

Before plays the original source, which has no audio track. Lip-synced plays what the workload returned, with its audio. Both show the same 6.8 seconds, encoded the same way, with no retouching or editing.

Demo disclosure: the voice track was supplied separately. The person in the clip did not say these words; Jinova Compute generated the matching mouth movement.

Uses

Where it helps.

Any time the audio you have and the video you have need to match.

Creator content

Tidy a take or swap a line without filming it again.

Localised versions

Already have the translated voice-over? Match the speaker to it.

Training videos

Bring presenter-led lessons in line with updated narration.

Product demonstrations

Keep a walkthrough current when the script changes.

Marketing content

Produce versions of a spot from recordings you already have.

Replacing narration

Re-record the audio, then bring the video along with it.

With permission, always

If a video shows a real person, you need their permission for what you are asking Jinova to do, or a licence that covers it.

Acceptable Use Policy
Jinova Compute

Describe the workload. Jinova handles the compute.

Lip Sync Video is one of the workloads on Jinova Compute. Say what you need in the console or pick the workload, approve the price, and Jinova runs it.

Nothing runs until you approve the price, and you are never charged more than the amount you approve.

Before you upload

The practical questions.

Your files stay yours

You keep ownership of the video and audio you upload and of the result Jinova produces for you. We process your files to deliver your result and for nothing else.

An account is required

Uploading and processing happen inside a signed-in account, so your files and results are not sitting behind a public link.

Help if something goes wrong

If a job or a charge does not look right, contact us and we will look into it.

How we handle your data

What we collect, how long we keep it and who processes it is set out in our Privacy Policy.

Full detail is in our Privacy Policy and in the Jinova Compute terms shown in the console.

FAQ

Questions about lip sync with Jinova.

What you supply, what you get back and what it costs.

Does Jinova create the voice or the words?

No. You supply the audio track, whether you recorded it or produced it some other way. Jinova Compute does not write, voice, clone or translate speech. It changes the speaker's mouth movement in your video to match the audio you provide.

What do I need to upload?

Two files: the video of the person speaking, and the audio track you want the video to follow. You download the lip-synced video when the job is done.

Can I use it for other languages?

Yes, if you already have the audio in that language. Jinova does not translate or dub. Bring a translated voice-over and Jinova Compute matches the speaker's mouth to it.

Whose videos can I use?

Footage you have the right to change. If a video shows a real person, you need their permission for what you are asking Jinova to do, or a licence that covers it, as the Acceptable Use Policy in the Jinova console sets out. Content designed to deceive people about who said something is not allowed.

Will I know the cost before it runs?

Yes. The console shows the amount to approve before the job runs. Nothing runs until you approve it, and you are never charged more than the amount you approve. Current prices and the terms for Jinova Compute purchases are shown in the console.

Is the demo on this page real?

Yes. It is one run of the live Lip Sync Video workload: the source clip and the audio track shown went in, and the lip-synced video shown came back. The page plays web copies of the 4K files, encoded the same way for both sides, and the audio is the exact file supplied. Nothing was retouched or edited.

What happens to uploaded files?

You keep ownership of your files and results. Jinova processes your files to produce the result you asked for. What we collect, why, and how long we keep it is set out in our Privacy Policy at /privacy-policy/.

Bring the video. Bring the audio.

Jinova Compute does the synchronising. Nothing runs until you approve the price.

Lip Sync Video is one of the workloads on Jinova Compute. It runs in the Jinova console at app.jinovaai.com.
