Kling V1.6 Text-to-Video Standard
Kling V1.6 Text-to-Video Standard is Kuaishou’s reliable text-to-video generation model that creates high-quality videos from text descriptions. Generate smooth, cinematic videos with natural motion and excellent visual fidelity — perfect for content creators and marketers.
Why It Stands Out
- High-quality generation: Produces detailed videos with natural motion and visual clarity.
- Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
- Negative prompt support: Exclude unwanted elements for cleaner outputs.
- Flexible aspect ratios: Choose from 16:9, 9:16, or 1:1 to fit any platform.
- Flexible duration: Generate 5 or 10 second videos.
- Guidance control: Adjust how closely the output follows your prompt.

Pro Tips for Best Quality
- Be detailed in your prompt — describe subject, action, environment, lighting, and mood.
- Include style keywords like “magical realism,” “cinematic,” or “mystical tone.”
- Use negative prompts to reduce artifacts like blur or distortion.
- Choose the right aspect ratio: 16:9 for widescreen, 9:16 for mobile, 1:1 for social squares.
- Lower guidance scale (0.3–0.5) for more natural results, higher for strict prompt adherence.
Notes
- Processing time varies based on duration and current queue load.
- Please ensure your prompts comply with content guidelines.
