Kling Motion Brush is the masking layer Kuaishou added on top of the Kling video pipeline. Most image-to-video models animate everything in the frame; Motion Brush lets you mark which regions should move and how, leaving everything else static. The result is cinemagraph-quality clips where the source still character holds while only the chosen elements come alive.
I tested Motion Brush on portrait, product, and landscape stills to see where the regional control actually changes the output meaningfully.
What is Kling Motion Brush?
Motion Brush is a feature layer on klingai.com that runs on top of any Kling video version. You upload a still, paint regions, and assign motion vectors (direction, intensity). The model animates only those regions.
The feature shines on cinemagraph work, ecommerce reels with subtle product motion, and portrait shots that need only the hair or fabric to move.
The test results
Test 1. Cinemagraph: portrait + hair
Prompt: “Still of a woman against a window. Mask only the hair; assign downward motion vector. Background and face stay frozen.”
Output looked exactly like a high-end cinemagraph: the woman frozen, only the hair flowing. No other image model produces this level of regional control out of the box.
Test 2. Ecommerce product with breath of motion
Prompt: “Sneaker on white background. Mask only the laces; assign a slow swaying motion. Rest of the shoe and the background stay frozen.”
Laces swayed, shoe stayed rigid. Useful for product reels where you want a hint of life without rotating the whole shot.
Test 3. Landscape with water
Prompt: “Mountain lake still. Mask only the water; assign ripple motion. Mountains and sky stay frozen.”
Water rippled, mountains held still. This is the classic cinemagraph use case and Motion Brush nails it.
The annoying parts
Brush UX. Painting precise masks takes practice. The first 5-10 attempts are usually wonky.
Extra credit cost. Motion Brush runs as an additional step on top of a Kling render, so it consumes more credits than a plain image-to-video.
No audio. Visual only, like the rest of Kling outside Omni.
Is it worth the price?
For ecommerce, lifestyle, and editorial content that benefits from cinemagraph treatment, Motion Brush is the cleanest option in 2026. The extra credit cost is justified by the regional control no other model offers.
