# Subtitles API

> Incruste des sous-titres stylisés dans une vidéo, à partir d'une transcription automatique ou de votre propre SRT, avec traduction facultative

Ajoute des sous-titres rendus à une vidéo (`video_url`) à l'aide d'un `preset` de style obligatoire, avec 30 préréglages disponibles. Le modèle transcrit automatiquement, ou ignore cette étape si vous fournissez `srt_file_url` ou `srt_content`. `language` définit la langue source pour améliorer la précision, et `translation_language` traduit les sous-titres. Une liste `vocabulary` de 100 termes maximum et des paramètres `customization` permettent d'affiner le résultat.

- Model id: `veed/subtitles`
- Made by: VEED
- Category: Video to Video
- Output: video
- Price per minute of your input video: from $0.10 / minute of input video (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.com/v1/run/veed/subtitles`
- Quote: `POST https://api.doitong.com/v1/quote/veed/subtitles`
- Docs page: https://doitong.com/fr/developers/models/veed/subtitles

## Pricing

Price: **from $0.10 / minute of input video** (the lowest tier; the quote prices your exact input). Price per minute 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:

- base rate: $0.10 / minute of input video
- above 1080p: $0.20 / minute of input video

The full example input below costs $0.20 = 200 API credits (1 min input video × $0.20).

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/veed/subtitles` 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.

Sans langue cible, les sous-titres restent dans la langue parlée d'origine. |
| `srt_file_url` |  | string (file URL) \| null | no |  | 1 – 2083 characters | Fournissez les sous-titres au lieu d'effectuer une transcription en téléversant un fichier .srt ou en collant son URL. |
| `srt_content` |  | string \| null | no |  |  | Texte brut des sous-titres au format SRT, fourni à la place de srt_file_url. Sa fourniture contourne la transcription. |
| `vocabulary` |  | array of object {word, replaces} \| null | no |  | ≤ 100 items | Vocabulaire de transcription facultatif, actif uniquement si ni srt_content ni srt_file_url n'est fourni. Incluez les noms de marques et le jargon spécialisé que les fournisseurs de transcription orthographient souvent mal, par exemple "VEED" → "vid". |
| `vocabulary[].word` |  | string | yes |  | 1 – 100 characters | Fournissez l'orthographe correcte du terme, de préférence une marque, un nom de produit ou un terme spécialisé de votre domaine. |
| `vocabulary[].replaces` |  | array of string | yes |  | 1 – 20 items | Répertoriez chaque faute d'orthographe une fois pour la remplacer par `word`. La correspondance exige un mot complet, mais ignore la casse : `['vid']` correspond à `vid`, `Vid` et `VID`, sans entrées distinctes pour chaque casse. |
| `customization` |  | object {position, shadow, text_customizations} \| null | no |  |  | Personnalisation facultative du préréglage, conservant les valeurs par défaut lorsque des champs sont omis. Les remplacements peuvent ajuster le placement vertical et l'intensité de l'ombre, ainsi que la police, la graisse et la couleur hexadécimale séparément pour chaque niveau d'importance des mots. |
| `customization.position` |  | enum (string) \| null | no |  | `top`, `center`, `bottom` | Position à l'écran sur l'axe vertical pour les sous-titres statiques. |
| `customization.shadow` |  | enum (string) \| null | no |  | `none`, `min`, `mid`, `max` | Amélioration de la lisibilité des sous-titres sur des arrière-plans clairs ou visuellement chargés. |
| `customization.text_customizations` |  | object {baseline, highlighted} \| null | no |  |  | Paramètres d'apparence du texte par niveau, couvrant les mots de base et les mots mis en évidence. |
| `customization.text_customizations.baseline` |  | object {font, weight, color} \| null | no |  |  | Apparence du texte par défaut pour tous les mots de la transcription, visible avant que l'un des mots ne reçoive une mise en évidence. |
| `customization.text_customizations.highlighted` |  | object {font, weight, color} \| null | no |  |  | Style du niveau de mots intermédiaire, que les préréglages mettent généralement en évidence avec une taille ou une graisse supérieure. Les mots passent automatiquement à ce niveau lorsqu'ils sont signalés comme importants, notamment les noms clés, les verbes d'action et les adjectifs saillants. |

File parameters (`video`, `srt_file_url`) 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",
  "preset": "glass"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "preset": "glass"
}
```

## 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/veed/subtitles?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",
    "preset": "glass"
  }'

# 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/veed/subtitles?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "preset": "glass"
  }),
});
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",
    "preset": "glass",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/veed/subtitles", 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": "veed/subtitles",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
        "preset": "glass"
      },
      "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.
