An advanced AI model designed for converting images into high-quality videos. It allows users to generate dynamic video content with smooth motion and detailed textures from still images or text prompts, significantly enhancing creative workflows in multimedia production.

## Setup your API Key

If you don’t have an API key for the AI/ML API yet, feel free to use our [Quickstart guide](https://docs.aimlapi.com/quickstart/setting-up).

## How to Make a Call

<details>

<summary>Step-by-Step Instructions</summary>

Generating a video using this model involves sequentially calling two endpoints:

* The first one is for creating and sending a video generation task to the server (returns a generation ID).
* The second one is for requesting the generated video from the server using the generation ID received from the first endpoint.

Below, you can find both corresponding API schemas.

</details>

## API Schemas

{% hint style="success" %}
Now, all of our API schemas for video models use our new universal short URL — `https://api.aimlapi.com/v2/video/generations`.\
However, you can still call this model using the legacy URL that includes the vendor name.
{% endhint %}

### Video Generation

You can generate a video using this API. In the basic setup, you need only an image URL and the aspect ratio of the desired result. The model can detect and use the aspect ratio from the input image, but for correct operation in this case, the image's width-to-height ratio must be between `0.5` and `2`.

## POST /v2/video/generations

>

```json
{"openapi":"3.0.0","info":{"title":"AIML API","version":"1.0.0"},"servers":[{"url":"https://api.aimlapi.com"}],"paths":{"/v2/video/generations":{"post":{"operationId":"_v2_video_generations","requestBody":{"required":true,"content":{"application/json":{"schema":{"type":"object","properties":{"model":{"type":"string","enum":["gen3a_turbo"]},"prompt":{"type":"string","maxLength":1000,"description":"The text description of the scene, subject, or action to generate in the video."},"image_url":{"type":"string","format":"uri","description":"A HTTPS URL or data URI containing an encoded image to be used as the first frame of the generated video."},"tail_image_url":{"type":"string","format":"uri","description":"A HTTPS URL or data URI containing an encoded image to be used as the last frame of the generated video."},"aspect_ratio":{"type":"string","enum":["16:9","9:16"],"default":"16:9","description":"The aspect ratio of the generated video."},"duration":{"type":"integer","description":"The length of the output video in seconds.","enum":[5,10],"default":"5"},"seed":{"type":"integer","minimum":0,"maximum":4294967295,"description":"Varying the seed integer is a way to get different results for the same other request parameters.

```

### Retrieve the generated video from the server

After sending a request for video generation, this task is added to the queue. This endpoint lets you check the status of a video generation task using its `id`, obtained from the endpoint described above.\
If the video generation task status is `completed`, the response will include the final result — with the generated video URL and additional metadata.

## Full Example: Generating and Retrieving the Video From the Server

<details>

<summary>How it works</summary>

Let’s take a beautiful but somewhat barren mountain landscape:

<figure><img src="https://upload.wikimedia.org/wikipedia/commons/thumb/6/68/Liebener_Spitze_SW.JPG/1280px-Liebener_Spitze_SW.JPG" alt=""><figcaption><p><a href="https://commons.wikimedia.org/wiki/File:Liebener_Spitze_SW.JPG">commons.wikimedia.org</a></p></figcaption></figure>

Then ask Gen4 Turbo to populate it with an epic reptilian creature using the following prompt:

*<mark style="background-color:blue;">"A menacing evil dragon appears in a distance above the tallest mountain, then rushes toward the camera with its jaws open, revealing massive fangs. We see it's coming"</mark>*

We combine both methods above in one program: first it sends a video generation request to the server, then it checks for results every 10 seconds.

{% hint style="warning" %}
Don’t forget to replace `<YOUR_AIMLAPI_KEY>` with your actual AI/ML API key from your [API Key management page](https://aimlapi.com/app/keys/) — in **both** places in the code!
