# Ltx 2.3 Quality · Render to Real API

> Tiontaíonn sé píosaí rindreála 3D, CG nó cluiche ina bhfíseán fótaréalaíoch, le déine inroghnaithe

Tiontaíonn sé rindreáil 3D a sholáthraítear mar `video_url` go cuma níos réadúla. Is féidir le `intensity` a bheith light, strong nó strong-v2, ó éadrom go dian. Socraíonn `image_url` roghnach an chéad fhráma fótaréalaíoch, agus cuireann `enable_detail_refine` pas géaraithe eile leis le `detail_refine_strength` ó 0.3 go 0.95. Coinníonn an leid an truicear `3DREAL`, agus is é 480p nó 720p an t-aschur.

- Model id: `ltx-2.3-quality/render-to-real`
- Made by: Lightricks
- Category: Video to Video
- Output: video
- Price per megapixel of your output video: from $0.00241 / megapixel of output video (cheapest run $0.003 (3 API credits))
- Run: `POST https://api.doitong.com/v1/run/ltx-2.3-quality/render-to-real`
- Quote: `POST https://api.doitong.com/v1/quote/ltx-2.3-quality/render-to-real`
- Docs page: https://doitong.com/ga/developers/models/ltx-2.3-quality/render-to-real

## Pricing

Price: **from $0.00241 / megapixel of output video** (the lowest tier; the quote prices your exact input). Price per megapixel 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:

- base rate: $0.00241 / megapixel of output video
- detail refine: $0.00963 / megapixel of output video

The full example input below costs $0.27 = 270 API credits (112 MP output video × $0.002408).

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-2.3-quality/render-to-real` 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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | URL chuig físeán 3D, CG nó cluiche-rindreáilte le haghaidh tiontú fótaréalaíoch. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | Ancaire íomhá roghnach do fhráma 0, a shocraíonn a chuma fhótaréalaíoch. Gan é, ní threoraíonn ach an rindreáil an toradh; nuair a chuirtear ar fáil é, bíonn an íomhá ina chéad fhráma, i gcomhréir le hoiliúint íomhá-go-fhíseán an oiriúnaitheora. |
| `intensity` |  | enum (string) | no | `light` | `light`, `strong`, `strong-v2` | Leibhéal claochlaithe fótaréalaíoch, agus `strong-v2` ag roghnú an oiriúnaitheora nua feabhsaithe le haghaidh comhleanúnachais níos fearr idir radhairc, fuaim, carachtair labhartha agus cáilíocht fhoriomlán. Maidir leis na roghanna eile, roghnaigh `light` chun níos mó de chuma agus de ghluaiseacht na rindreála foinse a chaomhnú, nó `strong` le haghaidh athruithe níos ionsaithí i dtreo an fhótaréalachais. |
| `enable_detail_refine` |  | boolean | no | `false` |  | Cumasaíonn sé céim bhreise scagtha chun géire agus taifeach a mhéadú; díchumasaithe de réir réamhshocraithe. Tar éis na giniúna bunúsaí, méadaíonn upscálaí spásúil an latent físeáin faoi 2x, ansin déanann pas gearr mionsonraitheora é a scagadh leis an tsamhail dhriogtha. |
| `detail_refine_strength` |  | number | no | `0.75` | 0.3 – 0.95 | Neart dí-noisithe an mhionsonraitheora, réamhshocraithe go 0.75 agus infheidhme le `enable_detail_refine` cumasaithe amháin. Le haghaidh eagarthóireachta níos séimhe a chaomhnaíonn an toradh bunúsach, úsáid socrú níos ísle; athghineann méadú air sonraí ar bhealach níos fairsinge ach méadaíonn sé an baol diallta. |
| `prompt` |  | string | no | `3DREAL.` |  | Leid téacs don toradh fótaréalaíoch inmhianaithe, scríofa tar éis truicear gníomhachtaithe an oiriúnaitheora réamh-líonta `3DREAL`. Ní bhaineann imréiteach na leide ná leathnú na leide an truicear sin; coinnítear i gcónaí é. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Roghnaigh taifeach an taobh ghearr den aschur agus cóimheas gné na foinse á choinneáil: tugann 480p torthaí níos boige do ghearrthóga suas le thart ar 15 soicind, agus tugann 720p torthaí níos géire suas le thart ar 6 soicind. Roghnaigh 480p do ghearrthóga níos faide toisc go gcuireann cosán rialaithe IC-LoRA teorainn ar thaifeach iolraithe faoi chomhaireamh frámaí; diúltaítear d’iarratais a sháraíonn an buiséad sin le hearráid shoiléir. Ríomh fad an aschuir mar `num_frames` / `frames_per_second`. |
| `num_frames` |  | integer | no | `121` | 9 – 481 | Comhaireamh frámaí aschuir, faoi réir buiséid IC-LoRA ar thaifeach iolraithe faoi fhrámaí: thart ar 6 soicind ag 720p nó 15 soicind ag 480p. Filleann sárú an bhuiséid 422; laghdaigh `num_frames` nó roghnaigh 480p. Is ionann fad an ghearrthóga i soicindí agus `num_frames` / `frames_per_second`. |
| `frames_per_second` |  | number | no | `24` | 1 – 60 | Ráta fráma físeáin aschuir, tomhaiste ina fhrámaí sa soicind. |
| `num_inference_steps` |  | integer | no | `15` | 8 – 30 | Socraigh cé mhéad céim tátail atá le rith, suas le 30; má fhágtar gan athrú é, úsáidtear 15. |
| `guidance_scale` |  | number | no | `1` | 1 – 20 | Coigeartaigh treoir saor ó aicmitheoir ag úsáid an scála seo; díríonn a thiúnadh réamhshocraithe ar ardchaighdeán agus giniúint thapa araon. |
| `generate_audio` |  | boolean | no | `true` |  | Scorán riain fuaime don MP4 a chuirtear ar ais: cruthaíonn as comhad físeáin amháin, agus cuireann air fuaim san áireamh. |
| `negative_prompt` |  | string | no | `color distortion, overexposure, static, blurry details, subtitles, style, artwork, painting, frame, still, dim overall tone, worst quality, low quality, JPEG compression artifacts, ugly, mutilated, extra fingers, poorly drawn hands, poorly drawn face, deformed, disfigured, malformed limbs, fused fingers, motionless frame, cluttered background, three legs, crowded background, walking backwards` |  | Leid dhiúltach a shonraíonn cad ba cheart don ghiniúint a sheachaint. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Saibhriú AI ar an leid giniúna, díchumasaithe de réir réamhshocraithe ionas go dtéann do fhoclaíocht tríd gan athrú. Tuairiscíonn an t-aschur an leid a úsáideadh i ndáiríre, agus coinníonn sé `3DREAL` i gcónaí; ligeann leathnú cumasaithe do shamhail AI an tuairisc a mhionsaothrú roimh an nginiúint. |
| `seed` |  | integer \| null | no |  |  | Síol a fhágann giniúint in-atáirgthe. Má shocraítear é go None, roghnaítear síol go randamach. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Rialaíonn sé an bhfuil seiceáil sábháilteachta cumasaithe. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Réamhshocrú cáilíochta a chuirtear i bhfeidhm ar an bhfíseán aschuir. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Mód scríofa an fhíseáin a bheidh mar thoradh air. |

File parameters (`video`, `image`) 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.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-2.3-quality/render-to-real",
      "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.
