Sample prompt · generate a video directly
The technique comes first, followed by the scene, action, performance and duration. Paste it straight into a video model and swap in your own characters and plot.
Close shot, facing front: the front door on New Year's Eve, a mother looks at her son who has just come in, her eyes red; even, soft light; when she speaks her lips move clearly and her expression is natural, her head moving only slightly, the background a blurred hallway light. Line: “You're home, that's what matters. The dumplings are still hot.” Upload the voice recording of this line first, then generate the lip sync, 5 seconds.
04
Common pitfalls
- A profile or a covered mouth makes the lip sync fail.
- Lines too long and the second half drifts out of sync.
- The voice's emotion doesn't match the face.
05
Parameter tips
Facing front or slightly angled, mouth unobstructed; keep each line under 5 s; settle the voice before generating the lip sync.
