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.

How to Use

  1. Upload or paste the URL of your image as the starting frame.
  2. (Optional) Upload a last_image if you want the video to end on a specific frame or design.
  3. Write your prompt, specifying subject, scene, motion, and style.
  4. (Optional) Add a negative_prompt to filter out unwanted artifacts or styles.
  5. Adjust guidance_scale to balance between strict prompt following and looser creativity.
  6. Choose the duration (5 s or 10 s).
  7. Run the model, preview the result, then iterate by tweaking the prompt, images, or guidance_scale until you reach the desired look.
