# Wan VACE 14B · Reframe API

> Endurrömmun VACE 14B-myndbands í nýtt stærðarhlutfall, með aðdrætti og sniðnum römmum; kvaðning valfrjáls

Tekur `video_url` og endursetur það fyrir annað `aspect_ratio` (auto, 16:9, 1:1 eða 9:16). `prompt` er valfrjáls. `zoom_factor` (0 til 0.9) skerðir inn í rammann og `trim_borders` fjarlægir brúnir. Fjöldi ramma og rammatíðni samsvara sjálfgefið inntakinu og `resolution` er frá 240p til 720p.

- Model id: `wan-vace-14b/reframe`
- Made by: Alibaba
- Category: Video to Video
- Output: video
- Price per second of your output video: from $0.04 / second of output video (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan-vace-14b/reframe`
- Quote: `POST https://api.doitong.com/v1/quote/wan-vace-14b/reframe`
- Docs page: https://doitong.com/is/developers/models/wan-vace-14b/reframe

## Pricing

Price: **from $0.04 / second of output video** (the lowest tier; the quote prices your exact input). Price per second of your output video: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

Price by tier:

- 240p: $0.04 / second of output video
- 360p: $0.04 / second of output video
- 480p: $0.04 / second of output video
- 580p: $0.06 / second of output video
- auto: $0.08 / second of output video
- 720p: $0.08 / second of output video

The full example input below costs $1.50 = 1500 API credits (18.75 s output video × $0.08 (auto)).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/wan-vace-14b/reframe` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

| `frames_per_second` |  | integer \| null | no | `16` | 5 – 30 | Rammatíðni myndbandsins sem verður til, aðeins notuð þegar `match_input_frames_per_second` er ekki true; leyfileg gildi eru 5–30 rammar á sekúndu. |
| `seed` |  | integer \| null | no |  |  | Sáðgildi sem gerir efnisgerð endurtekningarhæfa. Ef það er stillt á None er sáðgildi valið af handahófi. |
| `resolution` |  | enum (string) | no | `auto` | `auto`, `240p`, `360p`, `480p`, `580p`, `720p` | Upplausn úttaksmyndbandsins. |

| `num_inference_steps` |  | integer | no | `30` | 2 – 50 | Fjöldi sýnatökuskrefa, þar sem lengri úrvinnslutími skilar betri gæðum eftir því sem fjöldinn eykst. |
| `guidance_scale` |  | number | no | `5` | 1 – 10 | Styrkur samræmingar við kvaðningu, stýrður með classifier-free guidance; hærri kvarði hvetur myndir sem verða til til að fylgja textanum nánar. |

| `last_frame_url` | `end_image` | string \| null | no |  |  | Valfrjáls tilvísun í síðasta ramma send með vefslóð fyrir líkanið við úrvinnslu myndbandsins. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Öryggisathugunarrofi þar sem slökkt stilling krefst heimildar reiknings. Án þeirrar heimildar er sérhver beiðni athuguð óháð stillingunni; true virkjar athugunina. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Stýrir því hvort kvaðning sé útvíkkuð. |
| `acceleration` |  | enum (string) \| null | no | `regular` | `none`, `low`, `regular` | Stilling fyrir hraðari ályktun, með valinu 'none' eða 'regular': hröðun eykur vinnsluhraða verulega en breytir úttakinu lítillega. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Gæðastig myndbandsins sem verður til. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Skrifhamur myndbandsins sem verður til. |
| `num_interpolated_frames` |  | integer | no | `0` | 0 – 5 | Fjöldi innskotsramma: 0 skilur upprunalegu rammana eftir án innskots; önnur gildi tilgreina hversu marga milliramma á að búa til á milli þeirra. |

| `enable_auto_downsample` |  | boolean | no | `false` |  | Sjálfvirk aðlögun rammafjölda: með því að virkja þetta getur líkanið unnið úr tímalega niðurúrtökðu myndbandi af hæfilegri lengd, en innskot endurheimtir upphaflegan rammafjölda síðar. |
| `auto_downsample_min_fps` |  | number | no | `15` | 1 – 60 | Lágmarks rammatíðni, í römmum á sekúndu, sem leyfð er eftir undirúrtöku. Fyrir myndefni með lítilli hreyfingu leyfir lækkun þessa gildis meiri undirúrtöku og lengri runur; mjög hröð hreyfing gæti krafist hærra gildis, en sjálfgefið gildi hentar flestum myndböndum. Sjálfvirk undirúrtaka notar þessi mörk til að finna lægsta stuðulinn sem varðveitir smáatriði. |
| `interpolator_model` |  | enum (string) | no | `film` | `rife`, `film` | Val á líkani fyrir rammabilun: annaðhvort 'rife' eða 'film'. |

| `trim_borders` |  | boolean | no | `true` |  | Stýrir því hvort brúnir myndbandsins séu skornar af. |

File parameters (`video`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json

  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/wan-vace-14b/reframe?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/wan-vace-14b/reframe?wait=20", {

let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/wan-vace-14b/reframe", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "wan-vace-14b/reframe",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
