# LTX Video-0.9.7 13B Distilled API

> Tekst u video sa starijim destiliranim modelom 0.9.7 13B, uz podršku za LoRA modele i velik broj kadrova

Generira video iz obaveznog `prompt` koristeći destilirani model 0.9.7. Rezolucija je 480p ili 720p, omjer slike 9:16, 1:1 ili 16:9, a `num_frames` može biti od 9 do 1441 pri 1 do 60 fps. Svaki od dvaju prolaza uzorkovanja traje 2 do 12 koraka. Dostupni su neobavezni `loras`, dodatni prolaz detalja i proširivanje prompta.

- Model id: `ltx-video-13b-distilled`
- Made by: Lightricks
- Category: Text 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/ltx-video-13b-distilled`
- Quote: `POST https://api.doitong.com/v1/quote/ltx-video-13b-distilled`
- Docs page: https://doitong.com/hr/developers/models/ltx-video-13b-distilled

## 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.

The full example input below costs $0.202 = 202 API credits (5.0417 s output video × $0.04).

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/ltx-video-13b-distilled` 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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Tekstualne upute koje usmjeravaju generiranje. |
| `negative_prompt` |  | string | no | `worst quality, inconsistent motion, blurry, jittery, distorted` |  | Negativne tekstualne upute za generiranje. |
| `loras` |  | array of object {path, weight_name, scale} | no | `[]` |  | LoRA težine primijenjene tijekom generiranja. |
| `loras[].path` |  | string | yes |  |  | Lokacija LoRA težina, navedena kao URL ili putanja. |
| `loras[].weight_name` |  | string \| null | no |  |  | Naziv težine LoRA-e za odabir među višestrukim težinama u repozitoriju HuggingFace; potreban je samo za repozitorije s više težina. Ova postavka nema učinka osim ako `path` označava repozitorij HuggingFace. |
| `loras[].scale` |  | number | no | `1` | 0 – 4 | Množitelj koji skalira LoRA težinu pri učitavanju. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Razlučivost izlaznog videozapisa. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `9:16`, `1:1`, `16:9` | Omjer širine i visine rezultirajućeg videa. |
| `seed` |  | integer \| null | no |  |  | Početna vrijednost koja kontrolira slučajnost tijekom generiranja. |
| `num_frames` |  | integer | no | `121` | 9 – 1,441 | Ukupan broj sličica za video. |
| `first_pass_num_inference_steps` |  | integer | no | `8` | 2 – 12 | Broj koraka zaključivanja za prvi prolaz. |
| `second_pass_num_inference_steps` |  | integer | no | `8` | 2 – 12 | Broj koraka zaključivanja za drugi prolaz. |
| `second_pass_skip_initial_steps` |  | integer | no | `5` | 1 – 11 | Početni broj koraka zaključivanja koji se izostavljaju tijekom drugog prolaza, čime se taj prolaz usmjerava na fine detalje umjesto na opsežne promjene. |
| `frame_rate` |  | integer | no | `24` | 1 – 60 | Brzina sličica za video. |
| `expand_prompt` |  | boolean | no | `false` |  | Proširivanje prompta putem jezičnog modela. |
| `reverse_video` |  | boolean | no | `false` |  | Obrnuti redoslijed reprodukcije videa. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Prekidač sigurnosne provjere čija se isključena postavka poštuje samo za ovlaštene račune. Svi zahtjevi bez tog ovlaštenja prolaze sigurnosne provjere. |
| `enable_detail_pass` |  | boolean | no | `false` |  | Neobavezni drugi prolaz poboljšanja koji poboljšava detalje videa kada je omogućen. |
| `temporal_adain_factor` |  | number | no | `0.5` | 0 – 1 | Jačina prilagodljive normalizacije instance (AdaIN), koja pri višim postavkama uravnotežuje dosljednost boja, a pri nižima veću varijaciju boja. Djeluje na generiranim blokovima osim prvog, normalizirajući distribucije boja kroz video kako bi pomogla suzbiti postupno povećanje zasićenosti ili kontrasta. |
| `tone_map_compression_ratio` |  | number | no | `0` | 0 – 1 | Razina kompresije mapiranja tonova, od bez kompresije pri 0.0 do najveće kompresije pri 1.0. Komprimiranje dinamičkog raspona videa na ovaj način poboljšava vizualnu kvalitetu. |

## Example input

Required parameters only:

  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/ltx-video-13b-distilled?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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/ltx-video-13b-distilled?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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 = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/ltx-video-13b-distilled", 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": "ltx-video-13b-distilled",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.

Close-up on the van's tires shows the gravel spraying, highlighting the speed and rugged terrain. Sunlight filters through the trees, casting dappled shadows on the van and the trail.
