Steps

1Upload the source video.
2Upload the new audio.

Steps

1Upload a clear portrait image.

If you use audio separation, preview the separated tracks before generating. Each track should contain only the matching speaker's voice while preserving the original timing.

Reference Images · Prompt

Reference Images

Cat reference image for video ad generation — @image1

Gorilla reference image for video ad generation — @image2

Baby reference image for video ad generation — @image3

Prompt

A cinematic, ultra-realistic SaaS video ad with native synchronized high-quality voiceover. At the opening frame, the bold white text "lipsync.studio" dynamically drops from the top, settling in the center with a soft organic bounce and a subtle glowing neon orange light, before scaling down to the bottom watermark. The camera dynamically zooms into @image1. The cat stands on stage holding the microphone, its whiskers twitching naturally and fur swaying as it speaks like a stand-up comedian, enthusiastically saying: "Why sing when you can just talk?". With a smooth slide-transition, it cuts to @image2. The cool gorilla leans its arm comfortably on the car window, blinking naturally and nodding its head as it talks in a deep, humorous voice: "Exactly, buddy. Just let AI do the talking." A fluid warp transition pans to @image3. The baby closed-eyes, swaying gently, holding the microphone with a natural grip, babbling happily with a sweet baby voice: "Try it for free now!". Photorealistic, 60fps fluid motion.

Video Ad Generation

Create a short product ad from multiple reference images and a detailed prompt. This is designed for branded clips where each scene needs a clear character, voice, and transition.

Use this model#1 Best Video Generation

2Paste a prompt that calls out @image1, @image2, and @image3.
3Describe the voiceover, camera movement, transitions, and on-screen brand text.

Keep each reference tag tied to one scene so the model can preserve character identity and scene order.

What Does Video Lip Sync AI Change?

Video lip sync adjusts mouth movement in existing footage to follow a replacement audio track. Start here when you already have a filmed or generated video and want to change its spoken or sung performance. Automatic script translation and prompt-generated scenes have their own dedicated workflows.

How to Lip Sync a Video with AI

Upload the source video, add replacement speech or singing audio, and choose a model for the scene. Review the output settings and cost before generation. When the result is ready, inspect mouth movement, faces, and difficult sections such as turns, cuts, and obstructions.

Choose the Right Video Lip Sync Workflow

Use mouth-focused editing when the original lips are clearly visible, speaker control when one character must be selected, or scene-aware generation for broader scene and speaker interpretation. Different clips need different approaches; compare a short excerpt before processing a larger project.

Create AI Lip Dubbing from Existing Footage

Replace dialogue, revise a narration, or synchronize a translated recording with the visible speaker. Prepare the replacement audio before submitting. If you need the platform to translate the original speech as well, use AI Video Translation rather than expecting ordinary lip sync to translate the script.

Why Choose This Video Lip Sync Workflow?

4K Detail and Videos up to 10 Minutes

Create sharp, longer performances for complete songs, stories, lessons, and client projects. Supported lip sync models offer output up to 4K and clips up to 10 minutes, with the available settings shown in the generator.

Real People, Anime, and Animal Characters

Bring more than a human headshot to life. Create performances with realistic portraits, anime faces, illustrated characters, and animals using the workflow suited to your source.

Control the Speaker, Expression, and Motion

Choose which character performs with visual masks in supported models, or direct facial expression and movement with a performance prompt. Keep the delivery focused on the character and emotion you want.

Strong Character Consistency

Keep the character recognizable through the performance, using the source face and reference details as the visual foundation. Build videos around the person, animal, or design your audience already knows.

Natural Dialogue and Singing Performances

Create spoken messages, narration, character dialogue, and song performances. Use your own voice or prepared audio to give each character the words, melody, and delivery you choose.

Daily Free Credits and a Complete Creative Workflow

Log in daily for credits to try a 7-second video with eligible base settings. Create images, prepare speech or music, animate the character, and review the result in one workspace.

Video Lip Sync and AI Dubbing Questions

How do I lip sync a video with AI?

Upload a video with a visible speaker and add the replacement audio. Choose a model, review its settings and credit cost, then generate the video. Check mouth movement and speaker assignment before downloading the result.

Which video lip sync model should I choose?

A mouth-focused workflow suits clips with clearly visible lips. Speaker control helps identify a character in a shared scene. Scene-aware options offer a different approach for footage with more complex scene or speaker changes. Test a representative excerpt first.

Can I control who speaks when several people appear?

The speaker-control workflow provides a mask for the intended character. Upload the source video first, then create the mask using the displayed guidance. Review the result to confirm the correct person follows the replacement audio.

What is AI lip dubbing?

AI lip dubbing adjusts a visible speaker’s mouth movement to follow another audio track. It can support dialogue replacement or a translated recording. This page provides that lip-dubbing workflow, rather than automatically translating your original script.

Can I use my own voice or a singing track?

Yes. Supply audio through the available audio controls. Clear speech or vocals give you a useful performance source. Preview the recording and test a short section before processing a longer song or voice-over.

Can I try deepfake lip sync online for free?

This workflow changes mouth movement to follow audio; face replacement is a separate capability. Any free allowance depends on your account and current availability. Check the selected model and displayed credit cost before generating a clip.

Why can turns, microphones, or cuts affect lip sync?

Obstruction, rapid motion, extreme angles, and small faces can make the mouth harder to interpret. Choose a suitable model and review those sections closely. Clear source footage and a short initial test help you assess whether the workflow suits the clip.

Does video lip sync automatically translate speech?

Ordinary video lip sync follows the replacement audio you supply. If you need the original speech translated into another language, start with AI Video Translation, which combines translation, dubbed speech, and lip sync.
