API Feature

Transfer Motion to Any Character

Make any image move naturally by applying motion from reference videos.

Vydra's Motion Transfer API uses Kling AI's advanced motion control technology to animate still images with realistic movement from reference videos.

Upload a character image and a motion reference video, and our API generates a new video where your character performs the same movements. Perfect for character animation, dance videos, and virtual actors.

Any Character

Works with photos, illustrations, AI-generated images, and 3D renders.

Frequently Asked Questions

What types of images work best?

Clear, well-lit images with visible full or upper body work best. Front-facing or 3/4 views produce the most natural results.

What's the maximum video length?

Reference videos can be up to 30 seconds. Longer videos should be split into segments.

Can I use copyrighted characters?

You're responsible for ensuring you have rights to use any characters or content. Vydra doesn't grant rights to third-party IP.

How do I get the best results?

Use high-quality source images, choose reference videos with clear visible motion, and write descriptive prompts.
