Sign up for free to unlock account-specific credits, rewards, and saved projects. ### Does free AI lip sync include a watermark? Free video lip sync results may include a watermark. Paid plans remove watermarks on video outputs. Photo free tools on Magic Hour do not add watermarks; lip sync is a video tool. ### What is AI lip sync? AI lip sync is technology that uses artificial intelligence to automatically synchronize a person’s lip and facial movements in a video with any audio track. The AI analyzes the audio timing, phonemes, and facial features to produce perfectly matched, natural-looking mouth movements—making it look like the person is actually speaking the new audio. Magic Hour’s Lip Sync AI works entirely in your browser with no software download required. ### Can I lip sync an AI avatar or talking-head video? Yes. Lip sync works on real talking-head footage and on AI avatar / virtual influencer clips when a face is clearly visible. Upload the avatar video, add your audio (or a dubbed track), and generate a synced MP4 for ads, education, or social. ### How does AI lip sync work? Upload a video with a visible face and an audio file with the speech you want to sync. Click Generate and the AI analyzes the audio waveform and maps mouth shapes frame by frame onto the face in your video. The result is a natural, seamless lip-synced video you can download as MP4. The entire process takes seconds to minutes depending on video length. ### What video formats, resolutions, and lengths are supported? We support MP4 and MOV files up to 4K resolution. The maximum video length is 10 seconds in the free tool and 83 minutes (at 24 FPS) in the full tool. For longer projects, split your content into segments. Both sRGB and Rec709 colorspaces work well. For best results, use front-facing footage with good lighting and a clearly visible face. ### 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. ### What languages does lip sync AI support? Magic Hour’s Lip Sync AI supports all languages worldwide. You can upload audio in any language, dialect, or accent—English, Spanish, French, German, Portuguese, Japanese, Korean, Mandarin, Hindi, Arabic, and more—and the AI will perfectly synchronize lip movements to match. This makes it ideal for video translation, content localization, and global distribution. ### How accurate is the lip synchronization? Our AI delivers industry-leading accuracy, producing results that are virtually indistinguishable from naturally recorded video. The system precisely matches mouth shapes, facial expressions, and subtle speech mannerisms frame by frame to create authentic, professional-quality lip sync. ### How long does processing take? Most lip sync videos process in under a minute for short clips. Processing time depends on video length, resolution, and complexity. You can monitor progress in real time and download your result as soon as it finishes. ### What types of videos can I lip sync? You can sync: - Real human videos (talking head, interviews, vlogs, ads) - AI-generated avatars (for virtual influencers, marketing, and education) - Animated characters (for lip-synced storytelling and dubbing)—best results with human-like characters (e.g. Pixar style) ### Can I use lip-synced videos commercially? Yes. Paid plan subscribers (Creator, Pro, or Business) hold full commercial rights to their lip-synced videos. You can use them for ads, social media, e-commerce, client work, and branded content. Free users can use outputs for personal, non-commercial purposes. ### Can I use lip sync for video translation and dubbing? Absolutely. Lip Sync AI is one of the most powerful tools for video dubbing and translation. Upload your video and a translated audio track, and the AI will re-sync lip movements to match the new language. This is ideal for: - Content localization (YouTube, TikTok, Instagram, movies) - E-learning and training videos - Marketing and advertisements - Dialogue replacement without reshooting ### Does lip sync AI have an API? Yes. We offer a robust API for developers and businesses. Full documentation is available at [docs.magichour.ai](https://docs.magichour.ai/), allowing you to integrate lip sync capabilities directly into your applications or workflows. You can get started with the API for free.
