Online EducatorFrequently Asked Questions
All you need to know about Lip Sync tool usage
What kinds of audio and visuals can I use with Lip Sync?
You can use static images (face/character), avatars, or existing video scenes for visuals. For audio you can upload voice‑overs, narration, character dialogue or even use text‑to‑speech scripts — and the tool will sync it with mouth movements in the visual.
Do I need to download the visual or audio before syncing?
No. You can launch the Lip Sync tool directly from the visual’s details page within the platform — the workflow is integrated and no download is required before syncing.
Can I adjust how the lips move or how fast the voice is delivered?
Yes. After the initial sync, you can tweak parameters such as voice speed, mouth‑movement intensity, accent/language, pause timing or playback speed to refine the output.
What formats can I export the synced output in?
You can export the synced clip as a video segment (MP4, etc.), or pass it directly into your video/motion tool for further editing, animation, transitions or social‑format conversion.
What are the licensing and usage rights for synced clips?
The output from the Lip Sync tool is subject to your subscription plan and the platform’s Terms of Use. Please check your plan details for commercial‑use rights, modifications, export permissions and redistribution guidelines.
