# Wan VACE 14B · Reframe API

> VACE 14B-tilpasning af en video til et nyt billedformat med zoom og beskæring af kanter; prompt valgfri

Tager en `video_url` og komponerer den på ny til et andet `aspect_ratio` (auto, 16:9, 1:1 eller 9:16). `prompt` er valgfri. `zoom_factor` (0 til 0.9) beskærer ind i billedet, og `trim_borders` fjerner kanter. Antal frames og billedhastighed matcher som standard inputtet, og `resolution` går fra 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.ru/v1/run/wan-vace-14b/reframe`
- Quote: `POST https://api.doitong.ru/v1/quote/wan-vace-14b/reframe`
- Docs page: https://doitong.com/da/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.ru/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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | no | `` |  | Tekstinstruktioner, der styrer videogenerering; valgfri ved reframing. |
| `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 anvendt ved generering af en video. |
| `match_input_num_frames` |  | boolean | no | `true` |  | Kilde til den genererede videos frameantal: false bruger `num_frames`, mens true kopierer inputvideoens frameantal. |
| `num_frames` |  | integer | no | `81` | 17 – 241 | Output-frameantal med et inklusivt interval på 81–241. |
| `match_input_frames_per_second` |  | boolean | no | `true` |  | Kilde til den genererede videos billedhastighed: false bruger `frames_per_second`, mens true kopierer inputvideoens billedhastighed. |
| `frames_per_second` |  | integer \| null | no | `16` | 5 – 30 | Genereret videos billedhastighed, kun anvendt når `match_input_frames_per_second` ikke er true; accepterede værdier er 5–30 frames per sekund. |
| `seed` |  | integer \| null | no |  |  | Seed, der gør genereringen reproducerbar. Indstilling til None vælger en seed tilfældigt. |
| `resolution` |  | enum (string) | no | `auto` | `auto`, `240p`, `360p`, `480p`, `580p`, `720p` | Opløsning for outputvideoen. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `16:9`, `1:1`, `9:16` | Højde-bredde-forhold for den resulterende video. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 50 | Antal samplingstrin, hvor længere behandlingstid byttes for bedre kvalitet, når antallet øges. |
| `guidance_scale` |  | number | no | `5` | 1 – 10 | Styrke for prompttilpasning via classifier-free guidance; en øget skala får de genererede billeder til at følge teksten tættere. |
| `sampler` |  | enum (string) | no | `unipc` | `unipc`, `dpm++`, `euler` | Sampler anvendt ved generering af video. |
| `shift` |  | number | no | `5` | 1 – 15 | Shift-indstilling anvendt ved generering af video. |
| `video_url` | `video` | string (video URL) | yes |  |  | Reframing-reference leveret som en URL, der peger på kildevideofilen. |
| `first_frame_url` | `image` | string \| null | no |  |  | Valgfri første-frame-reference leveret via URL, som modellen skal bruge ved behandling af videoen. |
| `last_frame_url` | `end_image` | string \| null | no |  |  | Valgfri sidste-frame-reference leveret via URL, som modellen skal bruge ved behandling af videoen. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Sikkerhedskontrol, hvis deaktivering kræver kontogodkendelse. Uden denne godkendelse kontrolleres alle anmodninger uanset indstillingen; true aktiverer kontrollen. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Styrer, om promptudvidelse er aktiveret. |
| `acceleration` |  | enum (string) \| null | no | `regular` | `none`, `low`, `regular` | Indstilling for inferensacceleration med valget 'none' eller 'regular': accelereret behandling giver en betydelig hastighedsforbedring på bekostning af en meget lille ændring i outputtet. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Kvalitetsniveau for den resulterende video. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Skrivetilstand for den resulterende video. |
| `num_interpolated_frames` |  | integer | no | `0` | 0 – 5 | Antal interpolationer: 0 lader de oprindelige frames være uinterpolerede; andre værdier angiver, hvor mange mellemliggende frames der skal genereres mellem dem. |
| `temporal_downsample_factor` |  | integer | no | `0` | 0 – 5 | Videos frame-springfaktor angivet som et heltal med automatisk opsampling én gang for hver nedsamplingsfaktor. Brug 0 for at deaktivere temporal nedsampling. |
| `enable_auto_downsample` |  | boolean | no | `false` |  | Automatisk tilpasning af frameantal: aktivering lader modellen behandle en temporalt nedsamplet video af passende længde, hvorefter interpolation gendanner det oprindelige frameantal. |
| `auto_downsample_min_fps` |  | number | no | `15` | 1 – 60 | Minimum frame rate i frames per sekund, der er tilladt efter downsampling. For optagelser med lav bevægelse giver en reduktion af denne værdi større downsampling og længere sekvenser; meget hurtige bevægelser kan kræve en højere værdi, selvom standarden passer til de fleste videoer. Automatisk downsampling bruger denne tærskel til at finde den laveste faktor, der bevarer detaljerne. |
| `interpolator_model` |  | enum (string) | no | `film` | `rife`, `film` | Valg af frame-interpolationsmodel: enten 'rife' eller 'film'. |
| `transparency_mode` |  | enum (string) | no | `content_aware` | `content_aware`, `white`, `black` | Transparenshåndtering for start- og slutframes, som bestemmer, hvordan deres transparente områder udfyldes. |
| `return_frames_zip` |  | boolean | no | `false` |  | Styrer, om et ZIP-arkiv med alle genererede frames også returneres; aktiveret når true. |
| `zoom_factor` |  | number | no | `0` | 0 – 0.9 | Sæt videoens zoom til 0 for at lade den være uændret. En positiv faktor forstørrer videoen i forhold til lærredet med den angivne mængde og beskærer de ydre kanter væk. |
| `trim_borders` |  | boolean | no | `true` |  | Styrer, om videokanter beskæres. |

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`.

### MCP

The MCP server at `https://api.doitong.ru/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.
