Kling 4.0 is an AI video generator that creates 1080p cinematic videos from text prompts or uploaded images. It runs entirely in a web browser and offers free starter credits.
What is Kling 4.0?
Kling 4.0 is a text-to-video and image-to-video AI model that produces 1080p MP4 clips up to 15 seconds long with multi-shot storytelling. It accepts text prompts (up to 800 characters with an optional smart expansion feature) or reference images as input, and outputs downloadable MP4 videos. The service is accessible through the Kling4.app website and is developed by the team behind the platform. It supports both 720p and 1080p resolution options.
Key Features
- Multi-Shot AI Director — Automatically interprets a script and generates complete multi-shot cinematic scenes with automatic camera control in a single click.
- Omni Native Audio — Generates character-driven dialogue with precise lip sync, supporting multilingual speech, dialects, and accents while keeping speakers clearly separated.
- Up to 15-Second Videos — Creates clips from 3 to 15 seconds in one generation, maintaining narrative flow. The UI offers 5-second and 10-second presets.
- Consistent Characters — Locks key characters and environments across shots so camera movement and scene changes do not break visual continuity.
- Flexible Storyboard Control — Builds videos from text prompts, reference images, or video inputs, and allows adjusting scenes by adding, editing, or removing elements at any time.
- Native-Level Text Rendering — Renders crisp, structured on-screen text without information loss, ideal for ads, subtitles, overlays, and e-commerce visuals.
- Smart Expansion — Auto-enhances short prompts to generate more detailed outputs (toggle on/off).
