# Ltx 2.3 Quality · Render to Real API

> Hubadilisha video ya 3D, CG au mchezo kuwa video yenye uhalisia wa picha, ikiwa na kiwango cha kuchagua

Hubadilisha kurenda ya 3D iliyotolewa kama `video_url` kuwa mwonekano halisi zaidi. `intensity` inaweza kuwa light, strong au strong-v2, kutoka laini hadi kali. `image_url` ya hiari huweka fremu ya kwanza yenye mwonekano wa picha halisi, na `enable_detail_refine` huongeza awamu ya pili ya kunoa yenye `detail_refine_strength` kutoka 0.3 hadi 0.95. Kidokezo huhifadhi kichochezi `3DREAL`, na tokeo ni 480p au 720p.

- 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/sw/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 inayoelekeza kwenye video iliyotengenezwa kwa 3D, CG au mchezo, kwa ubadilishaji wa uhalisia wa picha. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | Nanga ya hiari ya picha kwa fremu 0, inayoweka mwonekano wake wa uhalisia wa picha. Bila hiyo, renderi pekee huongoza tokeo; ikitolewa, picha huwa fremu ya kwanza kulingana na mafunzo ya picha-kwa-video ya adapta. |
| `intensity` |  | enum (string) | no | `light` | `light`, `strong`, `strong-v2` | Kiwango cha ubadilishaji wa uhalisia wa picha, ambapo `strong-v2` huchagua adapta mpya iliyoboreshwa kwa mshikamano bora kati ya mandhari, sauti, wahusika wanaozungumza na ubora wa jumla. Kwa chaguo nyingine, chagua `light` kuhifadhi zaidi mwonekano na mwendo wa renderi ya chanzo, au `strong` kwa mabadiliko makubwa zaidi kuelekea uhalisia wa picha. |
| `enable_detail_refine` |  | boolean | no | `false` |  | Huwasha hatua ya ziada ya uboreshaji ili kuongeza ukali na mwonekano; imezimwa kwa chaguomsingi. Baada ya uzalishaji wa msingi, kipandisha mwonekano cha anga huongeza latent ya video mara 2, kisha hatua fupi ya kusafisha maelezo huiboresha kwa kutumia modeli iliyosafishwa. |
| `detail_refine_strength` |  | number | no | `0.75` | 0.3 – 0.95 | Nguvu ya kuondoa kelele ya kisafisha maelezo, chaguomsingi ikiwa 0.75 na ikitumika tu `enable_detail_refine` ikiwa imewashwa. Kwa mabadiliko madogo yanayohifadhi tokeo la msingi, tumia mpangilio wa chini; kuuongeza huzalisha maelezo upya kwa upana zaidi lakini kuna hatari ya kutofautiana zaidi. |
| `prompt` |  | string | no | `3DREAL.` |  | Kidokezo cha maandishi cha tokeo linalohitajika la uhalisia wa picha, kilichoandikwa baada ya kichocheo cha uanzishaji wa adapta `3DREAL` kilichojazwa awali. Kufuta kidokezo au kuwezesha upanuzi wa kidokezo hakukuondoi kichocheo hicho; huhifadhiwa kila wakati. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Chagua mwonekano wa upande mfupi wa tokeo huku ukihifadhi uwiano wa kipengele wa chanzo: 480p hutoa matokeo laini zaidi kwa klipu za hadi takriban sekunde 15, huku 720p ikitoa matokeo makali zaidi kwa hadi takriban sekunde 6. Chagua 480p kwa klipu ndefu kwa sababu njia ya udhibiti ya IC-LoRA inaweka kikomo kwa mwonekano unaozidishwa kwa idadi ya fremu; maombi yanayozidi bajeti hiyo hukataliwa kwa hitilafu iliyo wazi. Kokotoa muda wa tokeo kama `num_frames` / `frames_per_second`. |
| `num_frames` |  | integer | no | `121` | 9 – 481 | Idadi ya fremu za tokeo, iliyo chini ya bajeti ya IC-LoRA ya mwonekano unaozidishwa kwa fremu: takriban sekunde 6 katika 720p au sekunde 15 katika 480p. Kuzidi bajeti hiyo hurudisha 422; punguza `num_frames` au chagua 480p. Muda wa klipu kwa sekunde ni sawa na `num_frames` / `frames_per_second`. |
| `frames_per_second` |  | number | no | `24` | 1 – 60 | Kiwango cha fremu za video ya tokeo, kinachopimwa kwa fremu kwa sekunde. |
| `num_inference_steps` |  | integer | no | `15` | 8 – 30 | Weka idadi ya hatua za inference za kuendesha, hadi 30; kuiacha bila kubadilishwa hutumia 15. |
| `guidance_scale` |  | number | no | `1` | 1 – 20 | Rekebisha mwongozo usio na classifier kwa kutumia kipimo hiki; urekebishaji wake chaguomsingi hulenga ubora wa juu na uzalishaji wa haraka. |
| `generate_audio` |  | boolean | no | `true` |  | Kigeuzi cha wimbo wa sauti kwa MP4 inayorejeshwa: ikiwa kimezimwa hutengeneza faili ya video pekee, na kikiwa kimewashwa hujumuisha sauti. |
| `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` |  | Kidokezo hasi kinachobainisha kile ambacho uzalishaji unapaswa kuepuka. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Uboreshaji wa kidokezo cha uzalishaji kwa kutumia AI, umezimwa kwa chaguomsingi ili maneno yako yapitie bila kubadilishwa. Tokeo huripoti kidokezo kilichotumiwa hasa, huku `3DREAL` ikihifadhiwa kila wakati; kuwezesha upanuzi huruhusu modeli ya AI kufafanua maelezo kabla ya uzalishaji. |
| `seed` |  | integer \| null | no |  |  | Seed inayofanya uzalishaji uweze kurudiwa. Kuiweka kuwa None huchagua seed bila mpangilio. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Hudhibiti ikiwa ukaguzi wa usalama umewashwa. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Preset ya ubora inayotumika kwenye video ya tokeo. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Hali ya kuandika ya video inayotokana. |

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.
