Kling AI offers 4 specialized video generation models: cinematic text-to-video with multi-shot support and native audio (3.0 Pro), character animation via video motion control (2.6 Motion Control), image-to-video with synchronized audio (2.6 Pro), and first/last frame interpolation (O1 Video). Each model includes configurable generation parameters and extended duration support up to 30 seconds.
Cinematic Text-To-Video With Audio
Generate multi-shot video sequences directly from text prompts. Kling 3.0 Pro interprets shot descriptions within your prompt and renders them as continuous video with natural transitions. Supports up to 1000 characters for detailed scene and action direction.
Duration & Format
Choose video length via dropdown: 5, 10, 20, or 30 seconds. Portrait, Square, or Landscape aspect ratios available. Multi-shot generation intelligently distributes shots across the selected duration with automatic scene sequencing.
Native Audio Generation
Toggle audio generation on (default enabled). Supports Chinese and English voice output. Other languages automatically translated to English. For English speech, use lowercase letters; for acronyms or proper nouns, use uppercase. Generates ambient sound and effects synchronized to visual content.
Shot Type Control
Choose between "customize" (manually define shots in prompt) or "intelligent" (model automatically determines shot sequence). Customize offers more control; Intelligent provides creative autonomy. Both modes apply multi-shot transitions automatically.
Video Motion Transfer
Animate any character or object using motion from an external video. Upload a reference character image and a motion control video. The model applies the motion pattern from the video to your character while maintaining visual consistency.
Character Image Requirements
Upload JPG/PNG under 25MB. Characters, backgrounds, and elements will be based on this reference image. Ensure clear body proportions, minimal occlusion, and character occupies more than 5% of image area for best results.
Motion Control Video
Upload video demonstrating desired motion. Duration limits depend on character_orientation: 10 seconds maximum for 'image' mode, 30 seconds maximum for 'video' mode. Motion extracted from entire video and applied to character reference.
Prompt Guidance
Optional prompt (1000 chars). Add character, action, scene details, or style guidance to shape the generated video. Without prompt, model infers context from reference image and motion video alone.
Image-to-Video with Native Audio
Animate a still image into motion video with automatically generated synchronized audio. Describe how the image should move, including motion direction, camera movement, pacing, mood, and audio context. Supports up to 2080 characters for detailed animation direction.
Reference Image Upload
Upload JPG/PNG under 25MB. The AI will animate this image into video with synchronized audio. Image quality, composition, and subject clarity directly impact output quality. Ensure subject fills a meaningful portion of the frame.
Prompt Composition
Describe animation, motion, and sound in detail (2080 char limit). Example: "Pan left across mountain landscape while wind howls and birds chirp." Audio generation interprets prompt context and produces matching ambient sound and effects.
Duration & Audio Sync
Video length up to 30 seconds. Audio is generated automatically based on the scene description in your prompt. Audio roughly synchronizes with visual motion but is not frame-accurate. Treat generated audio as guide for post-production replacement.
First & Last Frame Video Generation
Generate video by specifying both starting and ending frames. Upload first frame (required) and optionally last frame. Model interpolates motion and transitions between the two frames over the selected duration, creating smooth video progression.
First Frame (Required)
Upload the starting frame for your video (JPG/PNG). This establishes the initial scene, characters, and composition. Quality and detail of this frame directly impact video output quality. Ensure clear, well-composed reference.
Last Frame (Optional)
Upload ending frame to define video destination state. If omitted, model infers logical conclusion based on first frame and prompt guidance. Last frame constrains the motion path and final composition, enabling precise scene transitions.
Prompt Direction
Optional prompt (2080 chars) guides motion interpretation and pacing. Example: "Slow zoom into landscape with sunset lighting changes." Prompt influences how model interpolates between first and last frame. Without prompt, model infers natural motion.
| Model | Input Type | Key Features | Max Duration |
|---|---|---|---|
| Kling Video 3.0 Pro | Text Prompt | Multi-shot, native audio, shot type control, aspect ratio selection | 30s (5/10/20/30 dropdown) |
| Kling Video 2.6 Motion Control | Character Image + Motion Video | Motion transfer, character animation, visual consistency, prompt guidance | 10s (image mode) / 30s (video mode) |
| Kling 2.6 Pro | Image + Text | Image-to-video, native audio, synchronized animation, duration up to 30s | 30s |
| Kling O1 Video | First Frame + Optional Last Frame + Text | Frame interpolation, motion path control, optional endpoint definition | 30s |
- Multi-shot character consistency is imperfect. Characters may shift in appearance between shots, especially with large camera angle changes. Clothing color, facial features, and body proportions can drift across shots.
- Quality degrades in long clips. Videos approaching 30 seconds show noticeable quality reduction in the final 10 seconds — color drift, reduced detail, and motion artifacts become more common.
- Audio sync is loose. Generated audio roughly matches visual events but is not frame-accurate. A door closing on screen may produce the sound slightly before or after the visual event.
- Text rendering fails. Text in generated scenes — signs, screens, labels — will be garbled or illegible. This is consistent across all current video generation models.
- Complex physics break down. Water simulation, cloth dynamics, and object collisions produce unrealistic results. The model approximates these visually but does not simulate actual physics.
- Motion control accuracy varies. Shot type selection and motion parameters are guidelines. Results vary between generations with identical settings due to model stochasticity.
- Generation time scales with duration. A 30-second multi-shot clip takes significantly longer to generate than a 5-second single shot. Expect minutes, not seconds, for maximum-duration generations.
What is Kling AI and who made it?
Kling is developed by Kuaishou Technology, the Chinese tech company behind the Kwai short-video platform. Pixazo provides access through its platform layer. Pixazo does not own, train, or modify the Kling model.
Which model should I use?
Choose based on your input: Text prompts (3.0 Pro), character animation with motion (2.6 Motion Control), static image animation (2.6 Pro), or frame-to-frame interpolation (O1 Video). 3.0 Pro offers most creative freedom; O1 Video offers most control over motion path.
Can Kling generate 30-second videos?
Yes, all four models support up to 30 seconds. However, quality tends to be highest in the first 10-15 seconds and degrades toward the end. For maximum quality throughout, generate shorter clips and combine them in post-production.
Does Kling include audio in generated videos?
Kling 3.0 Pro and Kling 2.6 Pro generate native audio automatically. Audio captures environmental sounds and basic effects matched to visual content. Audio is functional for previews but not production-grade. Dialogue, music, and precise timing require post-production replacement.
What are the input size and duration limits?
Image uploads (character reference, first frame, last frame) are limited to 25MB and JPG/PNG format. Motion control videos for 2.6 Motion Control are limited to 10s (image mode) or 30s (video mode). All text prompts (3.0 Pro: 1000 chars; 2.6 Pro/O1: 2080 chars) have character limits. Generated videos max at 30 seconds across all models.
Can I use Kling API directly?
Explore the Kling API through Pixazo. API access provides programmatic control over all four models with identical feature sets to the playground interface. Authentication, rate limits, and usage-based billing apply.
