Wan 2.2 Speech to Video
Turn a portrait and a speech track into a talking video. Wan 2.2 lip-syncs the face in image to audio and animates head and body movement; the prompt sets the scene and gestures.
Fields
| Field | Type | Default | Notes |
|---|---|---|---|
prompt | string, required | — | Text instruction. |
image | image URL, required | — | Portrait to animate. JPEG, PNG, or WebP URL. |
audio | audio URL, required | — | Speech track (WAV/MP3) that drives the lips. |
num_frames | integer 40–120 | 80 | Frames to generate (40–120, 16 frames per second of video). |
resolution | 480p / 580p / 720p | 720p | Sets the rate. |
negative_prompt | string | — | What to avoid. |
seed | integer 0–2147483647 | random | Fix it to compare prompt changes. |
Billing
Billed per output second at the upstream rate: $0.10 at 480p, $0.15 at 580p, $0.20 at 720p. The default 80 frames is 5 seconds.
| Output | 480p | 580p | 720p |
|---|---|---|---|
| 80 frames (5s, default) | $0.50 | $0.75 | $1.00 |
| 120 frames (7.5s) | $0.75 | $1.125 | $1.50 |
Failed runs are not charged.
Prompting
- Describe gestures and setting; the lips follow the audio automatically.
- Use a front-facing portrait with the mouth clearly visible.
Limits
- Up to 120 frames (7.5 seconds) per request.

Create a SandBase API key and set it in your server environment. All requests use Bearer authentication.
export SANDBASE_API_KEY="YOUR_API_KEY"Keep the key on your server. Do not expose it in browser code or commit it to a repository.
3. Queue
Submit a request
POST to /v1/run with this model ID and its inputs. The request example above includes submission and polling.
Fetch request status and result
Use the returned run ID to poll until the status is completed, failed or timeout. Read output only after completed.
curl "https://api.sandbase.ai/v1/run/$RUN_ID" \
-H "Authorization: Bearer $SANDBASE_API_KEY"4. Files
Hosted files
Pass a publicly accessible file URL in the model’s image, video or audio field. Supported formats and limits are shown beside each Playground input.
Uploading images
Use the upload or replace control on supported image fields in the Playground. Video URL fields accept a hosted driving video; they do not imply video-upload support.
