This model generates up to 9-second clips at 4K, compared to lower resolutions and shorter durations in Ray 1.6. You can specify the first and last frames as images or extend previously generated videos by passing their generation IDs. Looped videos are also supported.

How to Make a Call
Step-by-Step Instructions
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.
API Schemas
Create a video generation task and send it to the server
You can generate a video using this API. In the basic setup, you only need a reference image and a prompt.
This endpoint creates and sends a video generation task to the server — and returns a generation ID.
post
Body
modelstring · enumRequiredPossible values:
promptstringRequired
The text description of the scene, subject, or action to generate in the video.
resolutionstring · enumOptional
The resolution of the output video, where the number refers to the short side in pixels.
Default: 1080pPossible values:
aspect_ratiostring · enumOptional
The aspect ratio of the generated video.
Default: 16:9Possible values:

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
The code below creates a video generation task, then automatically polls the server every 10 seconds until it finally receives the video URL.
curl -L \
