How to do it, step by step
Choose Seedance 2.5 and add a photo
Use a clear, front-facing photo with one person and the mouth visible. Portraits, illustrations and characters all work.
Turn on lip sync and upload audio
Switch on Lip sync with your audio and choose an MP3, AAC or WAV file up to 30 seconds and 2MB. Trim silence at the start and end first.
Match the clip length
Pick a video length at least as long as your audio, then describe the expression and camera, such as “smiles, slight head movement, slow push-in”.
Generate and download
The generator shows the price before you start. Download the MP4 with your audio when it is ready.
Prompts you can copy
Swap in your own subject and keep the structure: what moves, how the camera moves, and what stays the same.
Talking head
The woman looks into the camera and speaks naturally with small head movements and occasional blinks. Soft studio light, fixed camera, plain background.
A calm, front-facing setup gives the cleanest lip sync.
Singing portrait
The man sings with feeling, eyes half closed, swaying gently to the rhythm. Warm stage light, slow camera push-in.
Use a vocal track without loud music for the best mouth movement.
Product presenter
The presenter holds the product at chest height, speaks to the camera with a friendly smile and nods at the end. Bright, clean studio, fixed camera.
Good for short ads and product explainers.
Cartoon character
The cartoon character talks excitedly to the camera, with big expressions and small hand gestures. Keep the original drawing style and colors.
Drawn characters often look best with lively expressions.
Tips for better results
Clean audio gives clean lips
Speech with little background noise or music syncs best. Remove long pauses so the face is not still for seconds at a time.
One voice per clip
With two speakers in one file, the model may move the wrong mouth. Make one clip per speaker and join them in an editor.
Keep the camera calm
Big camera moves and turns away from the camera make lip sync harder. A fixed camera or a slow push-in works best.
Use voices you have the right to use
Upload your own voice or audio you have permission for, and don’t make real people appear to say things they never said.
