v2-master/text-to-video

This documentation is valid for the following list of our models:

klingai/v2-master-image-to-video

Compared to , this Kling model better aligns with the prompt and delivers more dynamic and visually appealing results.

API Schemas

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 two corresponding API schemas and an example with both endpoint calls.

Create a video generation task and send it to the server

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 generation_id, obtained from the endpoint described above. If the video generation task status is complete, the response will include the final result — with the generated video URL and additional metadata.

Code Example

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

This model produces highly detailed and natural-looking videos, so generation may take around 5–6 minutes for a 5-second video and 11-14 minutes for a 10-second video.
