# Wan 2.1 VACE Long Reframe API

> Tilpasser lange videoer scene for scene med VACE 2.1, med scenedeteksjon og tilbakeinnliming

Laget for lengre klipp: modellen oppdager scener, tilpasser hver scene og kan lime resultatet tilbake i originalvideoen med `paste_back`. `scene_threshold` (0 til 100) angir deteksjonsfølsomheten, der lavere verdier finner flere scener. Automatisk nedsampling er aktivert som standard. Tilbyr også `zoom_factor`, `trim_borders`, sideforhold og `resolution` fra 240p til 720p.

- Category: Video to Video
- Output: video
- Price per 2 seconds of your input video: from $0.04 / 2 seconds of input video (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan-vace-apps/long-reframe`

## Pricing

Price: **from $0.04 / 2 seconds of input video** (the lowest tier; the quote prices your exact input). Price per 2 seconds of your input 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 / 2 seconds of input video
- 360p: $0.04 / 2 seconds of input video
- 480p: $0.04 / 2 seconds of input video
- 580p: $0.06 / 2 seconds of input video
- auto: $0.08 / 2 seconds of input video
- 720p: $0.08 / 2 seconds of input video

The full example input below costs $0.40 = 400 API credits (5 × 2 s input 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-apps/long-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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | no | `` |  | Tekstinstruksjoner som styrer videogenerering; valgfritt ved omramming. |
| `negative_prompt` |  | string | no | `letterboxing, borders, black bars, bright colors, overexposed, static, blurred details, subtitles, style, artwork, painting, picture, still, overall gray, worst quality, low quality, JPEG compression residue, ugly, incomplete, extra fingers, poorly drawn hands, poorly drawn faces, deformed, disfigured, malformed limbs, fused fingers, still picture, cluttered background, three legs, many people in the background, walking backwards` |  | Negativ prompt brukt ved generering av en video. |
| `seed` |  | integer \| null | no |  |  | Seed som gjør genereringen reproduserbar. Hvis den settes til None, velges en seed tilfeldig. |
| `resolution` |  | enum (string) | no | `auto` | `auto`, `240p`, `360p`, `480p`, `580p`, `720p` | Oppløsning for videoen i utdataene. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `16:9`, `1:1`, `9:16` | Sideforhold for den resulterende videoen. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 50 | Antall samplingsteg; lengre behandlingstid byttes mot bedre kvalitet når antallet økes. |
| `guidance_scale` |  | number | no | `5` | 1 – 10 | Styrke for prompttilpasning, kontrollert gjennom classifier-free guidance; en økning av skalaen får genererte bilder til å følge teksten tettere. |
| `sampler` |  | enum (string) | no | `unipc` | `unipc`, `dpm++`, `euler` | Sampler brukt ved generering av video. |
| `shift` |  | number | no | `5` | 1 – 15 | Forskyvningsinnstilling brukt ved generering av video. |
| `video_url` | `video` | string (video URL) | yes |  |  | Referanse for omramming levert som en URL som peker til kildevideofilen. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Bryter for sikkerhetskontroll, der av-innstillingen krever kontogodkjenning. Uten denne godkjenningen kontrolleres hver forespørsel uavhengig av innstillingen; true aktiverer kontrollen. |
| `acceleration` |  | enum (string) \| null | no | `regular` | `none`, `low`, `regular` | Innstilling for inferensakselerasjon, med valget 'none' eller 'regular': akselerert behandling gir en betydelig hastighetsøkning på bekostning av en svært liten endring i utdataene. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Kvalitetsnivå for videoen som resultat. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Skrivemodus for videoen som resultat. |
| `enable_auto_downsample` |  | boolean | no | `true` |  | Bryter for automatisk nedsampling. |
| `auto_downsample_min_fps` |  | number | no | `6` | 1 – 60 | Minimumsbildefrekvens i FPS for automatisk nedsampling. |
| `interpolator_model` |  | enum (string) | no | `film` | `rife`, `film` | Valg av modell for bildeinterpolering: enten 'rife' eller 'film'. |
| `transparency_mode` |  | enum (string) | no | `content_aware` | `content_aware`, `white`, `black` | Transparensbehandling for start- og sluttbildene, som bestemmer hvordan de transparente områdene fylles. |
| `return_frames_zip` |  | boolean | no | `false` |  | Styrer om et ZIP-arkiv som inneholder hvert genererte bilde også skal returneres; aktivert når true. |
| `zoom_factor` |  | number | no | `0` | 0 – 0.9 | Sett videozoomen til 0 for å la den være uendret. En positiv faktor forstørrer videoen i forhold til lerretet med denne mengden og beskjærer bort ytterkantene. |
| `trim_borders` |  | boolean | no | `true` |  | Styrer om videokantene beskjæres. |
| `scene_threshold` |  | number | no | `30` | 0 – 100 | Terskel for scenegjenkjenning: lavere verdi øker antallet registrerte scener. Godtar verdier fra 0 til 100. |
| `paste_back` |  | boolean | no | `true` |  | Styrer om den endrede scenen limes tilbake i den opprinnelige videoen. |

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`.

## 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-apps/long-reframe?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \

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-apps/long-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.
