AI Lip Sync FAQs
Common questions about creating synchronized talking videos with Seedance.
What is AI lip sync?
AI lip sync aligns a visible speaker's mouth movement with spoken audio. The source can be a recorded video, an animated character, or a still image supported by the selected model.
Why use an AI lip sync tool?
It helps creators change dialogue, localize videos, build talking avatars, and update presenter content without filming every version again.
Can I try Seedance AI Lip Sync for free?
You can open the tool and review the available models and credit cost before generation. Available credits and pricing depend on your current account plan.
How long does AI lip syncing take?
Processing time varies with the model, source length, resolution, and current demand. Short, clean clips generally finish faster than longer or more complex inputs.
What kind of source video works best?
Use a clear, well-lit face with visible lips, limited occlusion, and steady framing. Extremely small faces, fast cuts, or hands covering the mouth can reduce accuracy.
Can I create lip sync videos in different languages?
Yes. You can use recorded or generated speech in different languages, then create a synchronized version for each audience.
Can I upload my own audio for lip syncing?
Yes. The lip sync workflow accepts a driving audio file so you can use recorded dialogue, narration, or generated speech. Supported formats and limits are shown in the uploader.
Can I use AI lip sync for commercial content?
Lip sync is useful for ads, product demos, courses, and localized campaigns. Make sure you hold the necessary rights and consent for the face, video, voice, script, and intended distribution.
