Generate Text to Video With LTX 2 Video (RTX 5090)

What it does

This service turns a text prompt or a source photo into a short LTX-2 video on a dedicated NVIDIA RTX 5090, and gives you a task ID to track progress.

Text to Video — Send a prompt, and optionally seed, model, length, quality, and resolution. Use the POST /v1/video/generate endpoint to start the job. length supports 3s, 5s, or 10s, quality can be fast, balanced, or best, and resolution can be sd or hd.

Image to Video — Send an image (base64-encoded) and a prompt describing the motion, and optionally seed, length (3s, 5s, or 10s), quality (fast, balanced, or best), and resolution (sd or hd). Use the POST /v1/video/i2v-ltx2 endpoint to animate a photo while keeping the composition of the source image — a good fit for ad mockups, product demos, and social content.

Both endpoints respond with status, message, and task_id so you can store the job and poll later. Poll the shared GET /v1/video/tasks/:task_id endpoint until the job reaches completed or error. The status response includes type, status, task_id, elapsed_s, and, when generation finishes, an output_url for the final MP4. If something fails, check the error field on the task response.

This service is a good fit for ad mockups, concept previews, social clips, and internal creative iteration where a short video draft is enough — whether starting from a text description or animating an existing photo.

Notes: Text-to-video and image-to-video with LTX-2 19B (distilled) on a dedicated NVIDIA RTX 5090. Text-to-video generates a ~5-second cinematic clip in ~30-60 seconds; image-to-video generates a ~5-second clip in ~30-60 seconds.

GUIDE

Quickstart

Generate a short text-to-video task from a prompt.

curl -X POST "https://api.eu.apyhub.com/mastera-ai/ltx-2-video-rtx-5090/v1/video/generate" \
  -H 'apy-token: $APY_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{
    "length": "3s",
    "model": "ltx2",
    "prompt": "A red fox running through fresh snow, slow motion, cinematic lighting",
    "quality": "fast",
    "resolution": "sd",
    "seed": 0
  }'

What you'll get back

Returns a JSON object with status, message, and task_id string fields. status indicates the job state, message contains a human-readable note, and task_id is the queued generation task identifier.

  "task_id": "67ddbf74b89f",
  "status": "queued",
  "message": "Video generation started. Poll GET /v1/video/tasks/{task_id}."

About this endpoint

What it does

Starts a text-to-video generation request using the LTX-2 model and returns a task identifier for tracking the job. The request body includes the text prompt and optional generation settings such as seed, length, quality, and resolution.

Request Body

Parameter	Type	Mandatory	Description
prompt	String	Yes	Text description of the video to generate.
seed	Integer	No	Random seed for reproducible generation. Default: `0`.
model	ENUM	No	Video model to use. Allowed value: `ltx2`. Default: `ltx2`.
length	ENUM	No	Approximate duration. Allowed values: `3s`, `5s`, `10s`. Default: `5s`.
quality	ENUM	No	Generation quality (inference steps). Allowed values: `fast`, `balanced`, `best`. Default: `fast`.
resolution	ENUM	No	Output resolution. Allowed values: `sd` (SD 480p), `hd` (HD 720p). Default: `sd`.

Response

Returns a JSON object with status, message, and task_id fields. The status is a string indicating the job state, message is a string, and task_id is the identifier for the submitted task.

Parameter	Type	Mandatory	Description
status	String	No	Job status. Example: `queued`.
message	String	No	Informational message returned by the service.
task_id	String	No	Identifier for the submitted task.

Notes

This endpoint kicks off an async job and returns immediately with a job identifier; the actual work runs in the background. Pair this call with the corresponding job_check endpoint — poll that until the status reaches a terminal state to retrieve the result. Extract the job id from task_id in the response.

About this endpoint

What this endpoint does

Image to Video Generator turns a photo into a short animated LTX-2 clip and gives you a task ID to track progress. Send an image (base64-encoded) and a prompt describing the motion, and optionally seed, length (3s, 5s, or 10s), quality (fast, balanced, or best), and resolution (sd or hd); the request is queued and processed on RTX 5090 hardware.

The POST /v1/video/i2v-ltx2 endpoint starts a generation task and returns a status, message, and task_id. Poll GET /v1/video/tasks/:task_id (same poller as the LTX-2 text-to-video endpoint) until the job reaches completed or error. The status response includes type, status, task_id, elapsed_s, and, when generation finishes, an output_url for the final MP4.

Use Image to Video Generator when you want to animate a product photo, portrait, or scene image into a short cinematic clip while keeping the composition of the source photo — a good fit for ad mockups, product demos, and social content.

Request Body

Parameter	Type	Mandatory	Description
prompt	String	Yes	The text description of the motion to generate.
image	String	Yes	Base64-encoded source image to animate.
seed	Integer	No	Random seed for reproducible generation. Default: `0`.
length	ENUM	No	Output clip duration. Allowed values: `3s`, `5s`, `10s`. Default: `5s`.
quality	ENUM	No	Generation quality tier. Allowed values: `fast`, `balanced`, `best`. Default: `fast`.
resolution	ENUM	No	Output resolution tier. Allowed values: `sd`, `hd`. Default: `sd`.

Response

Returns a JSON object with status, message, and task_id fields. status is a string indicating the job state, message is a string, and task_id is the identifier for the submitted task.

Parameter	Type	Mandatory	Description
status	String	No	Job status.
message	String	No	Additional message about the request or job.
task_id	String	No	The job identifier to use when checking progress.

Notes

This endpoint kicks off an async job and returns immediately with a job identifier; the actual work runs in the background. Pair this call with the video-get-task endpoint (GET /v1/video/tasks/:task_id) — poll that until the status reaches a terminal state to retrieve the result. Extract the job id from task_id.

Notes: Image-to-video with LTX-2 19B (distilled) on a dedicated NVIDIA RTX 5090. Generates a ~5-second clip in ~30-60 seconds.
