Frequently asked questions

Does Kling 3.0 Image-to-Video require an input image?

Yes. kling-3.0/image-to-video is an image-to-video route. The image establishes the subject and opening composition; the prompt directs motion, camera, and environmental change.

Which durations and resolutions does Kling 3.0 Image-to-Video support?

The current HiAPI contract supports 3–15s at 720p or 1080p or 4K. Check the page controls and API docs for the current options.

How is Kling 3.0 Image-to-Video billed?

Billing follows output duration and the selected tier. The page follows the global display unit, while the successful task record contains the final charge.

How can I improve subject consistency?

Use a clear, unobstructed source with a complete composition. Describe the main action and camera first, then name the appearance, material, and background relationships that must remain stable. Validate a short clip first.

The first frame defines subject, composition, and shape. Add a matching last frame only when the ending state must be fixed, leaving room for the intended motion.

Direct the transition, camera, and sound

Write the middle process in time order, state whether the camera is locked, preserve stable details, and place sound cues next to their matching events.
