What is AI Lip Syncing?

AI Lip Syncing is advanced technology that automatically synchronizes a subject's lip and facial movements in video with any audio track. Our cutting-edge algorithms analyze audio timing and facial features to create perfectly synchronized, natural-looking results that are indistinguishable from originally recorded video.

How do I get access to Lip Sync?

Lip Sync is immediately available to all Magic Hour users for free. You can access it in the free tool with no sign up required, or if you'd like more access, simply log in to your account and navigate to the Lip Sync tool in our video editing suite.

What languages does the Lip Sync AI support?

Lip Sync AI supports all languages globally, making it the most versatile tool in the market. Whether you're creating content in English, Spanish, Mandarin, Japanese, Arabic, or any other language, our AI adapts seamlessly to match speech patterns and lip movements with exceptional precision and naturalness.

Is there a limit to the length of the video that can be processed?

Currently, the maximum video length is 10 seconds in our free tool and 11 minutes (assuming 30 FPS) in our full Lip Sync tool. For longer projects, we recommend splitting your content into segments for optimal processing.

What do I need to create a Lip Sync?

To create a lip-sync video, you'll need:

  • A video file (MP4 or MOV, up to 4K resolution)
  • An audio file (MP3, WAV, or AAC)
  • A stable internet connection to process the video in the cloud

Is the AI Lip Sync tool free to use?

Yes! We offer 3 free lip syncs in our free tool each day, 400 frames for free if you sign up (about 16 seconds at 24 FPS), and 100 free frames daily so you can experience Magic Hour and create your first Lip Sync video at no cost. To process additional frames or unlock advanced features, you can subscribe to our Creator, Pro, or Business plans or purchase a frame pack tailored to your needs.

Can I use Lip Sync for video translation?

Absolutely! Magic Hour’s Lip Sync AI is the only technology that supports all languages worldwide. You can upload audio in any language, dialect, or accent, and our AI will perfectly synchronize the lip movements to match, making it ideal for content localization and global distribution.

How does AI Lip Sync improve video dubbing and translation?

Our AI can auto-translate and lip-sync videos by generating voiceovers in multiple languages while ensuring natural-looking lip movements. This makes it ideal for:

  • Content localization (movies, YouTube, social media)
  • E-learning & training videos
  • Marketing & advertisements

What video formats and resolutions do you support?

Our platform supports professional-quality MOV or MP4 files up to 4K resolution. Both ungraded and graded footage work well with our system, supporting sRGB and Rec709 colorspaces. For optimal results, avoid using footage with text overlays on faces, fade-in transitions, or side profile shots.

Do I need to download software to use the Lip Sync tool?

No, our Lip Sync AI runs entirely in your web browser with no downloads required. This cloud-based solution allows you to create professional lip-synced videos from any device with internet access.

Can I lip sync videos using my own voice?

Yes! You can either:

  • Record your own audio separately and upload it to synchronize with your video.
  • Use AI-generated voices or voice cloning in an online voice cloning tool for dubbing.

Does Lip Sync AI have an API?

Yes! We offer a robust API for developers and businesses. Full documentation is available at Magic Hour AI API Documentation allowing you to integrate our powerful lip sync capabilities directly into your applications or workflows. You can get started with the API for free.

How can AI lip sync benefit my content creation?

Beyond language translation, our Lip Sync AI enables:

  • Dialogue replacement – Modify dialogue or replace entire scripts without reshooting.
  • Script modifications – Adjust scripts for continuity edits.
  • Content personalization – Create custom avatars and virtual presenters for marketing, education, or entertainment.
  • Localization – Translate and sync videos into multiple languages for a global audience.
  • Entertainment – Add fun voiceovers, create animated storytelling, or generate interactive social media content.

How accurate is the lip synchronization?

Our advanced AI delivers industry-leading accuracy in lip synchronization, creating results that are virtually indistinguishable from naturally recorded video. The system precisely matches mouth shapes, facial expressions, and even subtle speech mannerisms to create authentic, professional-quality results.

Can I use Lip Sync AI for multiple speakers in one video?

Currently, our Lip Sync AI only supports single-speaker synchronization. However, we plan on adding multi-speaker synchronization in the future.

What types of videos can I lip sync to audio?

You can sync:

  • Real human videos (talking head, interviews, vlogs)
  • AI-generated avatars (for virtual influencers, marketing, and education)
  • Animated characters (for lip-synced storytelling and dubbing). Make sure animated characters are “human-like” e.g. Pixar style, for best results.
