Kling 3.0 & O3 — AI Video Generation by Kuaishou

Generate, animate, and edit AI videos using Kuaishou's Kling 3.0 and Kling Video O3 — featuring cinematic motion quality, realistic physics simulation, reference-based generation, and natural-language video editing.

Kling 3.0 excels at creating cinematic short clips with realistic motion, complex camera movements, and faithful prompt adherence. Kling Video O3 adds MVL (Multi-modal Visual Language) technology with reference-based generation and video editing capabilities. All models support optional synchronized sound generation.

Data usage note: This skill sends text prompts, image URLs, and video URLs to the Atlas Cloud API (api.atlascloud.ai) for video generation and editing. No data is stored locally beyond the downloaded output files. API usage incurs charges per second based on the model selected.

Polling Logic

processing / starting / running → wait 5s, retry (typically takes ~60-120s)
completed / succeeded → done, get URL from data.outputs[]
failed → error, read data.error

Atlas Cloud MCP Tools (if available)

If the Atlas Cloud MCP server is configured, use built-in tools:

atlas_generate_video(model="kwaivgi/kling-v3.0-pro/text-to-video", params={...})
atlas_get_prediction(prediction_id="...")

Implementation Guide

Determine task type:
- Text-to-video: user describes a scene/action in text
- Image-to-video: user provides an image to animate
- Reference-to-video: user wants to generate video using character/prop/scene references
- Video editing: user wants to modify an existing video
Choose model family:
- Kling V3.0 for standard text-to-video and image-to-video with negative prompts and cfg_scale control
- Kling Video O3 for MVL-enhanced generation, reference-based video, video editing, and longer durations (3-15s)
Choose tier:
- Pro for final output, client-facing content, or quality-critical use
- Standard for most production use, cost-effective generation
Extract parameters:
- Prompt: describe scene, action, camera movement, and visual details
- Negative prompt (V3 only): specify undesired elements (e.g., "blurry, distorted faces, watermark")
- Aspect ratio: infer from context (social reel→9:16, YouTube→16:9, square→1:1)
- Duration: V3 supports 5 or 10s; O3 supports 3-15s
- cfg_scale (V3 only): 0.5 default; increase toward 1.0 for stricter prompt adherence
- Sound: enable if user wants audio; disabled by default
Execute: POST to generateVideo API → poll result → download MP4
Present result: show file path, offer to play

Prompt Tips

Kling produces best results with detailed, descriptive prompts:

Scene + Action: "A chef flips a pancake in a busy kitchen, steam rising from the pan"
Camera direction: "Camera slowly pans left to reveal...", "Close-up tracking shot of...", "Aerial view sweeping over..."
Style: "cinematic", "documentary style", "slow motion", "timelapse", "anime style"
Negative prompts (V3): Use to avoid common issues — "blurry, low quality, distorted, watermark, text overlay"
cfg_scale tuning (V3): Lower values (0.3-0.5) give more creative freedom; higher values (0.7-1.0) follow the prompt more strictly
Reference-to-video (O3): Provide clear character/prop reference images for consistent results

Image Requirements for Image-to-Video

When using image-to-video models, the source image must meet these requirements:

Format: JPG, JPEG, or PNG
Size: Maximum 10MB
Dimensions: Minimum 300px on shortest side
Aspect ratio: Between 1:2.5 and 2.5:1
