Start with a clear creative job.

Lip sync is useful when the spoken audio is already defined and you need the visible delivery to follow it. Start with the audio and the face or video required by the selected model. This is a different job from asking a video model to invent the entire scene, and it benefits from a clean, easy-to-read view of the speaker.

What to bring

  • Authorized face or source video
  • Clean speech audio
  • A model-compatible duration and format

From brief to reviewed creative.

  1. 01

    Prepare the line

    Listen for clipped words, noise and unnecessary pauses. Finalize the words before paying to match the visible mouth motion.

  2. 02

    Select compatible media

    Choose Lip Sync and use the input type the selected model supports. Prefer a clear face with minimal obstruction and an appropriate frame.

  3. 03

    Review the full delivery

    Watch with sound at normal speed, then check difficult syllables and cuts. Reject a clip with distracting mouth or jaw changes.

A brief to adapt.

Illustrative starting point—replace it with your actual product and approved information.

Match this authorized presenter reference to the supplied speech. Preserve the face and framing; prioritize a natural delivery over exaggerated motion.

Before the asset becomes an ad.

  • Source and voice permissions are clear
  • Audio remains understandable
  • Timing works through the full clip

Available models, inputs and credit estimates depend on the selected workflow. Check the current controls before generating, and review the final asset in its intended placement.

Tools for this job.

Questions about this workflow.

Does every model accept both images and video?

No. The available face, video and audio inputs depend on the selected model. Follow its current controls and limits.

Can I use a different language?

Use speech the selected workflow supports and have a fluent speaker review pronunciation and meaning. Lip alignment alone does not validate a translation.
