V1.6 Pro Effects

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

• klingai/kling-video-v1.6-pro-effects

Try in Playground

A specialized video model that generates short clips based on reference images of people, applying one of several preset scenarios: two people hugging, kissing, or making a heart shape with their hands (requires 2 reference images), or a single person being humorously squished like clay or inflated like a balloon (requires 1 reference image).

Generated Video Examples (low-res GIF previews)

Theoretically, you can get acceptable results for the squish and expansion effects even when using photos of animals, inanimate objects, or even landscapes. The output can be unusual, but the video will be generated.

However, if you try to use such photos with the hug, kiss, or heart_gesture effects, you’ll receive an error saying “Could not detect face in the image” .

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

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.

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.

Code Example

In this example, we'll try to make two people from different photos (provided via URLs) form a romantic heart shape with their hands. No prompt is required — the effect is selected by setting the appropriate value for the effect_scene parameter.

For effects that involve two images, the first one will always appear on the left side of the video, and the second one on the right. Therefore, to achieve the most natural-looking result, you may sometimes need to swap the image order.

In videos featuring a single person (the squish and expansion effects), an audio track is also generated — a mix of music and material interaction sounds, such as rubber squeaks and similar effects.

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