Kling 3.0 Video Duration Guide
Longer clips are not automatically better. For production work, duration should be chosen around one clear action per shot, continuity risk and the cost of failed generations.
How GenVideoKit structures Kling 3.0 prompts
Separate subject motion from camera motion. State the starting pose/composition, the action progression and the end state precisely. Prioritize character/product identity, reference consistency and physically plausible movement. For multi-shot work, keep shot boundaries and continuity cues explicit.

Production shortcut
Use one main action per clip. If the idea needs several distinct beats, split it in Scene Builder instead of forcing everything into one long generation.

$0.068 / second How to choose clip length
- Use a short validation render for a risky motion or identity-heavy shot.
- Give the action enough time to complete naturally; avoid cramming several story beats into one generation.
- Split long ideas into connected scenes and use the previous last frame as the next visual anchor.
- Price retries, not only the final accepted duration.
