Features
Kling 2.5 Turbo Pro (Image-to-Video)
Kling 2.5 Turbo Pro turns a single image and a text prompt into cinematic video with fluid motion and accurate intent. A new text-timing engine, improved dynamics, and faster inference enable high-speed action and complex camera moves with stable frames, while refined conditioning preserves palette, lighting, and mood.
This version additionally supports first–last frame control: you can specify both a starting image and an ending image, and the model will animate a smooth transformation between them.
What makes it stand out?
-
Better prompt understanding Precisely parses multi-step, causal instructions and turns a single image and prompt into coherent, well-paced shots that stay true to your creative idea.
-
More realistic look and greater stability Improved dynamics and balanced training data closely mimic real-world motion, even at high speeds and with complex camera moves. Playback is smooth with fewer jitters, tears, and dropped details.
-
Detail and style consistency Refined image conditioning maintains color, lighting, brushwork, and mood, keeping frames visually unified even during aggressive motion or transitions.
-
First–last frame animation When you provide both an initial image and a last_image, Kling 2.5 Turbo Pro treats them as keyframes and generates a video that naturally evolves from the first to the last frame.
Inputs
-
image (required) The starting frame of your video. Composition, style, and subject are primarily taken from this image.
-
last_image (optional) An optional target frame. If provided, the model interpolates between image and last_image, creating a smooth visual evolution from start to end.
-
prompt (required) Text description of the scene, actions, camera movement, and style.
-
negative_prompt (optional) Things you want the model to avoid (for example, blur, text overlays, distortions).
-
guidance_scale Controls how strongly the model follows the prompt versus being more free-form. Lower values = more creative variation; higher values = stricter adherence to the prompt.
-
duration Length of the generated video:
- 5 seconds
- 10 seconds
Output: a single video clip of the chosen duration, animated from the initial image (and optionally toward the last_image) according to your prompt.
Designed For
- Marketing and brand teams – Consistent, on-brand motion spots, feature demos, and campaign assets.
- Creators / YouTubers / Shorts teams – Strong narrative motion that boosts watch-through and engagement.
- Film / animation studios – Previz, style tests, and technique exploration with reliable dynamics.
- Education and training – Turn static diagrams or slides into clear, animated explainers.
Pricing
| Duration | Price |
|---|---|
| 5 s | $0.35 |
| 10 s | $0.70 |
How to Use
- Upload or paste the URL of your image as the starting frame.
- (Optional) Upload a last_image if you want the video to end on a specific frame or design.
- Write your prompt, specifying subject, scene, motion, and style.
- (Optional) Add a negative_prompt to filter out unwanted artifacts or styles.
- Adjust guidance_scale to balance between strict prompt following and looser creativity.
- Choose the duration (5 s or 10 s).
- Run the model, preview the result, then iterate by tweaking the prompt, images, or guidance_scale until you reach the desired look.
