v2-master/image-to-video

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

• klingai/v2-master-image-to-video

Model Overview

Compared to v1.6, this Kling model better aligns with the prompt and delivers more dynamic and visually appealing results.

How to Make a Call

Generating a video using this model involves making two sequential API calls:

• 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 or extended video from the server using the generation ID received from the first endpoint.

Below, you can find both corresponding API schemas.

Retrieve the generated video from the server

After sending a request for video generation, this task is added to the queue. Based on the service's load, the generation can be completed in seconds or take a bit more.

Code Example (Python)

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.
