# Wan VACE 14B · Reframe API

> VACE 14B video kadrējuma pārveidošana jaunai malu attiecībai ar tālummaiņu un malu apgriešanu; uzvedne nav obligāta

Izmanto `video_url` un pārkomponē to citai `aspect_ratio` (auto, 16:9, 1:1 vai 9:16). `prompt` nav obligāts. `zoom_factor` (0 līdz 0.9) pietuvina kadru, bet `trim_borders` noņem malas. Pēc noklusējuma kadru skaits un kadru nomaiņas ātrums atbilst ievadei, bet `resolution` ir no 240p līdz 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/lv/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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |

| `match_input_num_frames` |  | boolean | no | `true` |  | Ģenerētā video kadru skaita avots: false izmanto `num_frames`, savukārt true kopē ievades video kadru skaitu. |
| `num_frames` |  | integer | no | `81` | 17 – 241 | Izvades kadru skaits ar ietverošu diapazonu 81–241. |
| `match_input_frames_per_second` |  | boolean | no | `true` |  | Ģenerētā video kadru nomaiņas ātruma avots: false izmanto `frames_per_second`, savukārt true kopē ievades video kadru nomaiņas ātrumu. |
| `frames_per_second` |  | integer \| null | no | `16` | 5 – 30 | Ģenerētā video kadru nomaiņas ātrums, kas tiek lietots tikai tad, ja `match_input_frames_per_second` nav true; pieļaujamās vērtības ir 5–30 kadri sekundē. |
| `seed` |  | integer \| null | no |  |  | Sēkla, kas padara ģenerēšanu atkārtojamu. Iestatot None, sēkla tiek izvēlēta nejauši. |
| `resolution` |  | enum (string) | no | `auto` | `auto`, `240p`, `360p`, `480p`, `580p`, `720p` | Izvades video izšķirtspēja. |

| `last_frame_url` | `end_image` | string \| null | no |  |  | Neobligāta pēdējā kadra atsauce, kas nodrošināta ar URL un ko modelis izmanto video apstrādē. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Drošības pārbaudes slēdzis, kura izslēgšanai nepieciešama konta autorizācija. Bez šīs autorizācijas katrs pieprasījums tiek pārbaudīts neatkarīgi no iestatījuma; true iespējo pārbaudītāju. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Kontrolē, vai ir iespējota uzvednes paplašināšana. |
| `acceleration` |  | enum (string) \| null | no | `regular` | `none`, `low`, `regular` | Secināšanas paātrināšanas iestatījums ar opciju 'none' vai 'regular': paātrināta apstrāde ievērojami palielina ātrumu, radot ļoti nelielas izmaiņas izvadē. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Iegūtā video kvalitātes līmenis. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Iegūtā video ierakstīšanas režīms. |
| `num_interpolated_frames` |  | integer | no | `0` | 0 – 5 | Interpolācijas reižu skaits: 0 atstāj sākotnējos kadrus bez interpolācijas; citas vērtības norāda, cik starpkadru jāģenerē starp tiem. |
| `temporal_downsample_factor` |  | integer | no | `0` | 0 – 5 | Video kadru izlaišanas koeficients, kas izteikts kā vesels skaitlis, ar automātisku iztveršanas palielināšanu pēc katra iztveršanas samazināšanas koeficienta. Izmantojiet 0, lai atspējotu laika iztveršanas samazināšanu. |
| `enable_auto_downsample` |  | boolean | no | `false` |  | Automātiska kadru skaita pielāgošana: iespējošana ļauj modelim apstrādāt piemērota ilguma video ar samazinātu laika iztveršanu, pēc tam ar interpolāciju atjaunojot sākotnējo kadru skaitu. |
| `auto_downsample_min_fps` |  | number | no | `15` | 1 – 60 | Minimālais kadru ātrums kadros sekundē, kas atļauts pēc iztveršanas samazināšanas. Mazkustīgiem materiāliem šīs vērtības samazināšana ļauj veikt lielāku iztveršanas samazināšanu un iegūt garākas secības; ļoti ātrai kustībai var būt nepieciešama lielāka vērtība, taču noklusējums ir piemērots lielākajai daļai video. Automātiskā iztveršanas samazināšana izmanto šo slieksni, lai atrastu mazāko koeficientu, kas saglabā detalizāciju. |
| `interpolator_model` |  | enum (string) | no | `film` | `rife`, `film` | Kadru interpolācijas modeļa izvēle: 'rife' vai 'film'. |

| `zoom_factor` |  | number | no | `0` | 0 – 0.9 | Iestatiet video tālummaiņu uz 0, lai to atstātu nemainītu. Pozitīvs koeficients palielina video attiecībā pret audeklu par norādīto apjomu, apgriežot ārējās malas. |
| `trim_borders` |  | boolean | no | `true` |  | Nosaka, vai video malas tiek apgrieztas. |

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`.

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" \

    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()

### 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.
