Why it matters

For marketers, small businesses and creators who make product and social video. Longer single takes and keyframe control mean fewer stitched clips and more control over how a product or character looks across a scene.

What's new

Native generation of 3 to 30 seconds in a single pass, and existing videos can be extended up to two minutes.
Omni Reference combines up to 15 reference assets (images, subjects, motion footage, voice) and up to 10 keyframes placed along the timeline.
Steadier large-scale motion and better handling of camera moves such as push-ins, pans, tracking and orbit shots, per Kling.
Targeted video editing of characters, products, backgrounds, camera angles and style.
Works through Kling MCP and CLI so AI agents can drive it; native 4K and 1080p 10-bit HDR output and enterprise/developer API access are announced as coming soon.

Taken from the project's own release notes. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: You make product, ad or social videos and want longer, more controllable AI clips than a few seconds at a time.

Worth knowing: 4K/1080p 10-bit HDR output and API access were announced as coming soon at launch, so check availability before planning around them.
