# LTX Video-0.9.7 13B Distilled · Image to Video API

> Převod obrázku na video se starším destilovaným modelem 0.9.7 13B z obrázku a promptu

Animuje obrázek na `image_url` podle povinného `prompt`. Zvolit lze 480p nebo 720p a `aspect_ratio` auto, 9:16, 1:1 nebo 16:9. `num_frames` má rozsah 9 až 1441 a `frame_rate` 1 až 60. Podporuje `loras`, volitelný průchod detailů a `reverse_video`.

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

## 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.ru/v1/quote/ltx-video-13b-distilled/image-to-video` 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 | yes |  |  | Textové pokyny řídící generování. |
| `negative_prompt` |  | string | no | `worst quality, inconsistent motion, blurry, jittery, distorted` |  | Negativní textové pokyny pro generování. |
| `loras` |  | array of object {path, weight_name, scale} | no | `[]` |  | Váhy LoRA použité během generování. |
| `loras[].path` |  | string | yes |  |  | Umístění vah LoRA zadané jako URL nebo cesta. |
| `loras[].weight_name` |  | string \| null | no |  |  | Název váhy LoRA pro výběr z více vah v repozitáři HuggingFace; vyžadují jej pouze repozitáře obsahující více vah. Toto nastavení nemá účinek, pokud `path` neurčuje repozitář HuggingFace. |
| `loras[].scale` |  | number | no | `1` | 0 – 4 | Násobitel škálující váhu LoRA při načítání. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Rozlišení výstupního videa. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `9:16`, `1:1`, `16:9`, `auto` | Poměr stran videa. |
| `seed` |  | integer \| null | no |  |  | Seed řídící náhodnost během generování. |
| `num_frames` |  | integer | no | `121` | 9 – 1,441 | Celkový počet snímků videa. |
| `first_pass_num_inference_steps` |  | integer | no | `8` | 2 – 12 | Počet inferenčních kroků v prvním průchodu. |
| `second_pass_num_inference_steps` |  | integer | no | `8` | 2 – 12 | Počet inferenčních kroků ve druhém průchodu. |
| `second_pass_skip_initial_steps` |  | integer | no | `5` | 1 – 11 | Počáteční počet inferenčních kroků vynechaných během druhého průchodu, čímž se tento průchod zaměří spíše na jemné detaily než na velké změny. |
| `frame_rate` |  | integer | no | `24` | 1 – 60 | Snímková frekvence videa. |
| `expand_prompt` |  | boolean | no | `false` |  | Rozšíření promptu pomocí jazykového modelu. |
| `reverse_video` |  | boolean | no | `false` |  | Obrácení pořadí přehrávání videa. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Přepínač kontroly bezpečnosti, jehož vypnutí se respektuje pouze u autorizovaných účtů. U všech požadavků bez tohoto oprávnění se provádějí bezpečnostní kontroly. |
| `enable_detail_pass` |  | boolean | no | `false` |  | Volitelný druhý průchod vylepšením, který po zapnutí zlepší detaily videa. |
| `temporal_adain_factor` |  | number | no | `0.5` | 0 – 1 | Síla adaptivní normalizace instance (AdaIN), která při vyšších hodnotách vyvažuje konzistenci barev a při nižších větší barevnou variabilitu. Funguje na vygenerovaných blocích kromě prvního a normalizuje rozložení barev v celém videu, aby pomohla omezit postupný nárůst sytosti nebo kontrastu. |
| `tone_map_compression_ratio` |  | number | no | `0` | 0 – 1 | Úroveň komprese mapování tónů od bez komprese při 0.0 po maximální kompresi při 1.0. Komprese dynamického rozsahu videa tímto způsobem zlepšuje vizuální kvalitu. |
| `constant_rate_factor` |  | integer | no | `29` | 0 – 51 | Konstantní faktor rychlosti (CRF) používaný pro kompresi vstupu, který může zlepšit kvalitu pohybu přiblížením dodaného média trénovacím datům modelu. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL zdrojového obrázku použitého ke generování videa. |

File parameters (`image`) 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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"

}
```

## 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.ru/v1/run/ltx-video-13b-distilled/image-to-video?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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

### Python

```python
import os
import requests

API = "https://api.doitong.ru/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",

r = requests.post(API + "/run/ltx-video-13b-distilled/image-to-video", 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.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": "ltx-video-13b-distilled/image-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
