12 parameters · 1 required · 11 optional
| Parameter | Type | Required | Description |
|---|---|---|---|
prompt | string | Required | The prompt to generate the video from. |
fps | number | Optional | The frames per second of the generated video. · Min: 1 · Max: 60 · Default: 25 |
seed | integer | Optional | The seed for the random number generator. |
num_frames | integer | Optional | The number of frames to generate. · Min: 9 · Max: 481 · Default: 121 |
video_size | string | Optional | The size of the generated video. · Options: square_hd, square, portrait_4_3, portrait_16_9, landscape_4_3, landscape_16_9 · Default: "landscape_4_3" square_hdsquareportrait_4_3portrait_16_9landscape_4_3landscape_16_9 |
camera_lora | string | Optional | The camera LoRA to use. This allows you to control the camera movement of the generated video more accurately than just prompting the model to move the camera. · Options: dolly_in, dolly_out, dolly_left, dolly_right, jib_up, jib_down, static, none · Default: "none" dolly_indolly_outdolly_leftdolly_rightjib_upjib_downstaticnone |
video_quality | string | Optional | The quality of the generated video. · Options: low, medium, high, maximum · Default: "high" lowmediumhighmaximum |
generate_audio | boolean | Optional | Whether to generate audio for the video. · Default: true |
use_multiscale | boolean | Optional | Whether to use multi-scale generation. If True, the model will generate the video at a smaller scale first, then use the smaller video to guide the generation of a video at or above your requested size. This results in better coherence and details. · Default: true |
video_write_mode | string | Optional | The write mode of the generated video. · Options: fast, balanced, small · Default: "balanced" fastbalancedsmall |
camera_lora_scale | number | Optional | The scale of the camera LoRA to use. This allows you to control the camera movement of the generated video more accurately than just prompting the model to move the camera. · Min: 0 · Max: 1 · Default: 1 |
video_output_type | string | Optional | The output type of the generated video. · Options: X264 (.mp4), VP9 (.webm), PRORES4444 (.mov), GIF (.gif) · Default: "X264 (.mp4)" X264 (.mp4)VP9 (.webm)PRORES4444 (.mov)GIF (.gif) |
Output Schema
| Field | Type | Description |
|---|---|---|
id | string | Unique identifier for the generation task |
status | string | Task status: pending, running, completed, failed, timeout |
model | string | Model used for the generation |
outputs | array | Array of output items |
outputs[].url | string | URL of the generated artifact |
outputs[].content_type | string | MIME type (e.g. image/png, video/mp4) |

error.message | string | Human-readable error description |
Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read
outputsfrom the completed response

LTX-2 19B Distilled
LTX-2 19B Distilled is a text-to-video creation endpoint in the LTX 2 19B family. It is built for creators who need to turn a concrete creative brief into a controlled visual sequence: the request establishes the source material, the intended subject behavior, the camera language, and the atmosphere of the finished shot. The distilled route keeps that workflow explicit instead of hiding its input assumptions behind a generic video-generation label.
In practice, this route accepts a written prompt as creative context and exposes num frames, video size, generate audio, camera lora for delivery planning. That makes it suitable for shot-based pipelines where teams must preserve a source, direct a transformation, or control the final format without losing sight of the model's central task. Write prompts as a compact shot plan—subject, action, setting, camera, light, and timing—then use the structured fields for constraints that should remain deterministic across iterations.
Highlights
- Scene built from language. No source image is required: the prompt defines subject, action, environment, camera, light, and temporal progression.
- Purposeful camera direction.
camera_loraoffers named dolly, jib, static, and lateral camera paths. - Native soundtrack option.
generate_audiocan request sound as part of the same generated scene. - Distilled-route format-first generation. Resolution, video size, aspect ratio, duration, or frame count can be fixed before rendering where the schema exposes them. This capability is exposed by the named distilled route and its exact request fields. For
lightricks/ltx-2-19b/distilled/text-to-video, this task-specific control is documented alongside the route’s own required inputs.

When to Use
| Scenario | Recommendation |
|---|---|
| Choose this route | Use it when the deliverable specifically calls for text-to-video creation, rather than a neighboring generation mode. |
| Prepare the source | Provide a precise written brief in the format described by the request schema. |
| Direct the shot | Describe the subject, action, environment, camera movement, lighting, and temporal progression in that order. |
| Control continuity | Use endpoint frames, reference media, strength, or audio controls when those fields are available instead of burying hard constraints in prose. |
| Plan delivery | Set duration, frame count, resolution, and aspect ratio explicitly when the schema exposes them, then compare iterations with a stable seed where supported. |
Prompt Guide
For text-to-video creation, describe one coherent shot rather than a list of visual keywords. Put the main subject and action first, follow with location and staging, then add camera movement, lens or framing, lighting, mood, and any timed change. Keep URLs and hard delivery choices in their dedicated fields.
