Speed, physics, and value
Kling 2.5 Pro was designed around three principles: speed, physics accuracy, and cost efficiency. At 3× faster than previous Kling models and 30% lower in cost, it’s the most practical HD Kling model for volume production workflows and budget-conscious professional content. The state-of-the-art physics engine handles realistic motion — gravity, momentum, and material behavior all render accurately, making Kling 2.5 Pro particularly strong for sports content, action scenes, and any footage where physical plausibility is important. Multi-reference support (up to 4 input images) enables character and style consistency across a generation.Capabilities
3× faster generation
Generates 3× faster than previous Kling Pro models — significantly reduces time-to-result for production workflows.
State-of-the-art physics engine
Gravity, momentum, and material behavior render accurately — noted as best-in-class for AI sports video due to realistic motion physics.
30% lower cost
30% more affordable than comparable previous Kling models — practical for high-volume and budget-sensitive production.
Multi-reference support
Accepts up to 4 reference images to anchor character appearance, visual style, and scene consistency.
1080p HD output
Full HD 1080p resolution at 5 or 10 seconds for professional deliverables.
Text and image input
Supports both text-to-video and image-to-video workflows with strong prompt adherence.

Write your prompt
Describe the scene, motion physics, camera behavior, and atmosphere. For sports or action content, describe the specific physical action explicitly.
Prompting tips
- Describe physics explicitly — “A soccer player kicks the ball with full force, realistic ball trajectory, natural spin” — the physics engine responds accurately to described physical events.
- Use references for consistent characters — For brand content or recurring characters, upload reference images to anchor visual identity across generations.
- Sports and action work well — Kling 2.5 Pro’s physics accuracy makes it particularly strong for sports footage, action sequences, and any physically demanding motion.
Example prompts
A tennis player serves a ball at full power. Slow-motion capture of the ball impact, realistic ball deformation and spin. Courtside, natural daylight. 5 seconds, 16:9.
Two fencers spar in an elegant dojo. Steel blades catch the light on each clash. Realistic weight and momentum in every movement. 10 seconds.
