In this guide, you’ll learn what lip syncing is, how to create a lip-sync video step by step, common pitfalls to avoid, and how to get the best results using AI.
What is a lip-sync video?
A lip-sync video is a visual content where a person’s mouth movements are aligned with an audio track, such as dialogue, voice-over, or lyrics. The result is a video that looks like the subject is naturally saying or singing the audio.
Lip syncing is used widely in:
- Entertainment: music videos, dance trends, and comedy skits.
- Marketing: branded videos with voice-over synced to spokespeople or characters.
- Education and accessibility: bubbing, translation, or inclusive visual content.
Lip-sync videos are effective because they’re expressive, relatable, and easily shareable across platforms.
Step-by-step: How to make an AI lip-sync video
With the Freepik AI-powered Lip Sync tool, you can create a video using just an image and an audio clip. Here’s how:
Step 1. Go to the Freepik Lip Sync tool
From the Freepik homepage, click on All tools in the left-hand menu. Scroll to the Video section and select Lip Sync from the list.
Step 2. Pick your starting image or video
Click Browse images to upload the file you want to animate.
You can start with:
- A high-resolution image (portrait or character-facing forward)
Step 3. Choose or create the voice for your video
You can decide how the subject will sound by either uploading existing audio or generating a voice with AI:
- Upload your own audio: Click the Audio tab to browse and upload a file (MP3 or WAV). This is ideal for voice-overs, music clips, or any prerecorded speech.
Generate a voice with AI: Click the Voice tab to create a voice track using Freepik’s AI voice generator. You can filter by language, gender, age, and even use case.
Step 4. Describe the video
In the Prompt box, describe what the video should look like. For example:
Prompt: Lip sync video of a young woman with shoulder-length brown hair, smiling and talking expressively to the camera. She is wearing a white t-shirt and standing in front of a soft yellow background. She uses expressive facial gestures, occasional hand movements, and natural pauses. The camera is steady, front-facing, 4K resolution, cinematic lighting.
This helps guide the AI to generate visual details that match the tone of the voice.
Step 5. Apply lip sync
Once your media and audio are set, click Apply lip sync. The AI will process everything and generate a video where the character or subject appears to speak naturally.
Step 6. Review and download
Once complete, your video will appear in the right-side panel. From here, you can:
- Preview the video.
- Retry if needed.
- Download and export to your device.
That’s it! You’ve created a lip sync video using AI with no need for manual editing.
Tips for better results for AI lip-sync videos
Creating a good lip-sync video requires attention to both the visuals and the audio. Here are some tips to improve quality:
Use high-quality assets

- Record clean audio with expressive delivery.
Write a visual prompt that matches the tone
- Align your visual prompt with the emotion and context of the audio.
- Mention style, lighting, and camera angle if relevant.
Keep it short and focused

Check expression and realism

- If the result feels off, try using a different image or video, or adjust the prompt and regenerate.
