Playground
Input
Text prompt describing the motion to generate.
PNG, JPEG, WebP, or GIF · 20 MiB maximum
URL of the image used as the first frame (JPEG, PNG, BMP, or WebP). Cannot be combined with `images`, `videos`, or `audios`.
This field is required.
Output duration in seconds (2-30), or `auto` to let the model pick a length from the prompt and inputs. `auto` is pre-authorized at 30 seconds and billed on the actual output length.
Output aspect ratio. Omit to match the input image.
Output resolution tier after FlashVSR super-resolution.
Advanced settings
PNG, JPEG, WebP, or GIF · 20 MiB maximum
URL of the image used as the last frame (JPEG, PNG, BMP, or WebP). Cannot be combined with `images`, `videos`, or `audios`.
Generate a synchronized audio track. Pricing is the same either way.
Random seed (0-2147483647) for reproducible results. Omit for a random seed; the same seed may still produce slightly different results. Range: 0 to 2147483647.

Wan 3.0 Pro Image to Video
Start a clip from your own picture. image becomes the exact first frame; add end_image and the model interpolates the motion between the two. Clips run 2–30 seconds with native audio. Pro runs the same Wan 3.0 model, then upscales the result with FlashVSR, so output comes back at 1080p, 2K, or 4K. For 480p or 720p use the non-Pro endpoints.
Fields
| Field | Type | Default | Notes |
|---|---|---|---|
prompt | string, required | — | Up to 5,000 characters. |
image | image URL, required | — | First frame. JPEG/PNG/BMP/WebP, 240–8000px per side, ≤20MB, no transparency. |
end_image | image URL | — | Last frame; needs image. |
duration | 2–30 or auto | 5 | auto lets the model pick the length. |
resolution | 1080p / 2k / 4k | 1080p | Output tier after FlashVSR super-resolution; sets the per-second rate. |
aspect_ratio | adaptive / 16:9 / 4:3 / 1:1 / 3:4 / 9:16 | adaptive | adaptive follows the prompt and inputs. |
generate_audio | boolean | true | Native dialogue, music, and effects. Same price on or off. |
seed | integer 0–2147483647 | random | Fix it to compare prompt changes. |
Billing
You pay for output seconds only: $0.18 at 1080p, $0.20 at 2K, $0.23 at 4K. Input images, audio, and video are not metered. The frame images are free.
| Output | Billed | 1080p | 2K | 4K |
|---|---|---|---|---|
| 2s | 2s | $0.36 | $0.40 | $0.46 |
| 5s (default) | 5s | $0.90 | $1.00 | $1.15 |
| 10s | 10s | $1.80 | $2.00 | $2.30 |
| 30s | 30s | $5.40 | $6.00 | $6.90 |
With duration: "auto" the run is pre-authorized at 30 seconds, then settled on the length that was actually generated. Failed runs are not charged. Output files are copied to SandBase storage and the returned URL stays valid for 7 days; download anything you need to keep.
Prompting
- Describe what moves, not what is already visible: “she turns toward the lens as wind lifts her scarf”.
- With two frames, keep them compatible in framing and lighting, or describe the transition explicitly.
- Leave
aspect_ratioonadaptiveto keep the image's own proportions.
The subject slowly turns toward the camera as a breeze moves the fabric; subtle handheld push-in, natural daylight, no dialogue.
Limits
- Reference images, videos, and audio are not accepted here; use reference-to-video instead.

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.

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.
