Use Volcengine Lip Sync on ReelPush with a required source video and driver audio, plus alignment controls for a focused audio-driven lip sync task. ## Volcengine Lip Sync on ReelPush Volcengine Lip Sync is ByteDance's audio-driven video-processing workflow. ReelPush sends an existing face video and separate driver audio, then exposes the integration's timing and scene controls. ## Volcengine Lip Sync capabilities available now 1 available variants, video input, 1 to 15 seconds, source video, and driver audio ### Keep the original performance The source video supplies the face, framing, and body movement. The model changes mouth timing around the driver audio. ### Control audio alignment ReelPush exposes alignment direction and template start controls so the timing decision is explicit before processing. ### Handle scene changes deliberately Scene detection is available for clips that contain cuts, but each shot still needs visual review after lip sync. ## How to use Volcengine Lip Sync on ReelPush ### 1. Prepare the face clip Choose a clear one to 15 second source video with a visible mouth and limited obstruction. ### 2. Upload final driver audio Use the exact spoken track intended for review, then set lip-sync and alignment controls. ### 3. Inspect every spoken segment Review mouth timing, teeth, jaw edges, cuts, expression, and audio synchronization before delivery. ## Three jobs suited to Volcengine Lip Sync ### Localized creator read Pair an approved talking-head clip with a translated voice track when consent and usage rights are in place. ### Corrected product narration Replace a short spoken line without rebuilding the entire source performance. ### Client-approved audio revision Test final driver audio against a locked face clip before the asset returns to editing. ## When to compare Volcengine Lip Sync with another model ### Lip sync or OmniHuman Volcengine starts from existing video. OmniHuman starts from a still portrait plus audio and creates the broader performance. [OmniHuman 1.5 Video Generator](https://reelpush.ai/models/omnihuman.md) ### Lip sync or InfiniteTalk InfiniteTalk creates a talking portrait from an image and audio. Lip Sync preserves more of a recorded source performance.

It does not automatically add final captions, verify claims, clear likeness or music rights, schedule posts, or publish to a channel. Review every output for identity, objects, movement, audio, brand rules, consent, and platform requirements before use. ## Related models and creation tools - [OmniHuman 1.5 Video Generator](https://reelpush.ai/models/omnihuman.md): Create person videos from a source image and driving audio with OmniHuman 1.5. - [InfiniteTalk Video Generator](https://reelpush.ai/models/infinitetalk.md): Create lip-synced person videos from a source image and driving audio with InfiniteTalk. - [Kling Video Generator](https://reelpush.ai/models/kling.md): Explore Kling video generation in one Account workspace. - [Text to Video AI](https://reelpush.ai/text-to-video.md) - [Image to Video AI](https://reelpush.ai/image-to-video.md) - [Video to Video AI](https://reelpush.ai/video-to-video.md) - [URL to Video AI](https://reelpush.ai/url-to-video.md) ## Volcengine Lip Sync questions, answered ### What files does AI lip sync need? This ReelPush workflow requires a source video and separate driver audio. The video should show the speaker's mouth clearly, and the audio should contain the final speech. Both inputs need appropriate consent, likeness rights, voice rights, and permission for the intended use. ### How long can a lip sync source clip be? The current Volcengine Lip Sync catalog entry accepts source durations from one to 15 seconds. Short clips make it easier to check mouth timing and scene boundaries. For a longer piece, process and review deliberate segments within the supported input contract. ### What does audio alignment change? Alignment controls determine how driver audio and the source template are positioned when their timing differs. ReelPush exposes forward and reverse alignment choices plus a template start value. Preview the result closely because a valid setting does not guarantee natural synchronization for every performance. ### Can I use lip sync without the speaker's consent? You should only use video, likeness, and voice material when you have the necessary rights and consent. ReelPush provides processing controls, while responsibility for authorization, disclosure, claims, and platform policy remains with the creator or account using the resulting asset. ## Start Creating Free [Open the editor](https://reelpush.ai/models/volcengine-lip-sync) [Log in](https://reelpush.ai/login) [Pricing](https://reelpush.ai/pricing.md) ## Core creation tools - [Text to Video AI](https://reelpush.ai/text-to-video.md): Turn a written prompt into a short-form video with reelpush.ai. - [Image to Video AI](https://reelpush.ai/image-to-video.md): Animate a source image into a video while reelpush.ai keeps your creative intent in view. - [Video to Video AI](https://reelpush.ai/video-to-video.md): Transform a source video into a new creative direction with reelpush.ai. - [URL to Video AI](https://reelpush.ai/url-to-video.md): Create a selected video type from a supported public URL without exposing the source link in an indexed page. --- ## More from reelpush.ai - [Home](https://reelpush.ai/.md) - [News](https://reelpush.ai/announcements.md) - [About](https://reelpush.ai/about.md) - [Privacy](https://reelpush.ai/privacy.md) - [Terms](https://reelpush.ai/terms.md) - [Site index for agents](https://reelpush.ai/llms.txt) Contact: contact@reelpush.ai ## Structured data ```json [ { "@context": "https://schema.org", "@type": "SoftwareApplication", "name": "Volcengine Lip Sync on ReelPush", "url": "https://reelpush.ai/models/volcengine-lip-sync", "applicationCategory": "MultimediaApplication", "operatingSystem": "Web", "description": "Use Volcengine Lip Sync on ReelPush with a required source video and driver audio, plus alignment controls for a focused audio-driven lip sync task.", "featureList": [ "Keep the original performance", "Control audio alignment", "Handle scene changes deliberately" ], "offers": { "@type": "Offer", "price": "0", "priceCurrency": "USD" } }, { "@context": "https://schema.org", "@type": "HowTo", "name": "How to use Volcengine Lip Sync on ReelPush", "step": [ { "@type": "HowToStep", "position": 1, "name": "Prepare the face clip", "text": "Choose a clear one to 15 second source video with a visible mouth and limited obstruction.", "url": "https://reelpush.ai/models/volcengine-lip-sync#model-step-1" }, { "@type": "HowToStep", "position": 2, "name": "Upload final driver audio", "text": "Use the exact spoken track intended for review, then set lip-sync and alignment controls.", "url": "https://reelpush.ai/models/volcengine-lip-sync#model-step-2" }, { "@type": "HowToStep", "position": 3, "name": "Inspect every spoken segment", "text": "Review mouth timing, teeth, jaw edges, cuts, expression, and audio synchronization before delivery.", "url": "https://reelpush.ai/models/volcengine-lip-sync#model-step-3" } ] }, { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "What files does AI lip sync need?", "acceptedAnswer": { "@type": "Answer", "text": "This ReelPush workflow requires a source video and separate driver audio.
