README

Overview

Kling VIDEO O3 Pro is a professional-grade multimodal video model that generates high-definition video with synchronized native audio from text or images.

It prioritizes visual detail, motion realism, and stable subject identity across frames. Kling O3 Pro supports reference-driven generation, structured multi-prompt sequencing, and prompt-based video editing with strong temporal consistency for production-quality output.

How it Works

Kling VIDEO O3 Pro uses an advanced multimodal generation pipeline combining language modelling, optional visual conditioning, and enhanced temporal coherence mechanisms to produce stable HD video with aligned audio.

Prompt Interpretation

The model interprets prompts to extract subject identity, motion, environment, tone, pacing, and camera direction. These signals guide both visual composition and synchronized audio generation throughout the clip.

Image-to-Video

Reference images anchor subject identity, styling, or composition. Output dimensions are automatically inferred from the provided image, maintaining layout and visual consistency.

Reference-Guided Generation

Up to seven reference images (or four when using a reference video) can guide identity, styling, or feature consistency. A single reference video may be used for feature reference in supported workflows.

Multi-Prompt Sequencing

Kling O3 Pro supports up to six structured prompt segments, enabling controlled shot transitions and pacing within a single clip.

High-Fidelity Video & Audio

Video and audio are generated natively and synchronously. Audio may include dialogue, ambient sound, and environmental effects aligned with on-screen timing. The Pro model emphasizes motion realism and subject stability across frames.

Key Features

  • Text-to-Video and Image-to-Video
    Unified multimodal video generation.
  • Higher-Fidelity Rendering
    Enhanced detail and motion realism.
  • Stable Subject Identity
    Reduced drift across frames and shots.
  • Structured Multi-Prompt Control
    Up to six sequential prompt segments.
  • Reference-Based Generation
    Supports images and one reference video.
  • Prompt-Based Video Editing
    Edit existing video while preserving temporal coherence.
  • Native Audio Output
    Dialogue, ambient sound, and effects generated with video.

How to Use

  1. Write a detailed prompt describing subjects, actions, and cinematic direction.
  2. (Optional) Provide reference images or a reference video.
  3. Structure scene progression using multi-prompt segments if needed.
  4. Select duration and supported dimensions.
  5. Submit the request and retrieve the generated clip.

Example prompt:
A cinematic rooftop confrontation at sunset, slow push-in toward two characters arguing, subtle wind movement in clothing, distant city ambience and soft dialogue exchange.

Tips for Better Results

  • Use structured multi-prompt segments for controlled transitions.
  • Provide consistent subject descriptors across prompts.
  • Use reference images to maintain character stability.
  • Specify camera movement for improved motion realism.
