🎬 Scene Builder

Create professional multi-scene videos with AI-powered generation. Build complex narratives by combining multiple scenes into seamless video experiences.

Overview

Scene Builder is a professional video creation tool that allows you to build multi-scene videos through an intuitive interface. It provides a seamless experience for creating complex video narratives by combining multiple scenes into a single continuous video.

Key Concept

Scene Builder allows you to create professional video scenes by adding multiple scenes with custom prompts. Each scene can be 5 or 8 seconds long, with a total duration constraint ensuring the last scene keeps the total under 30 seconds (final total can reach up to 37 seconds).

The system automatically processes scenes using text-to-video for the first scene and extend for subsequent scenes, creating a seamless video experience.

Use 5-second scenes for quick transitions and 8-second scenes for more detailed actions or establishing shots.

Write Detailed Prompts

Be specific about setting, action, atmosphere, and visual elements. Detailed prompts produce better results.

Use Style Settings

Experiment with different styles (anime, cyberpunk, etc.) to match your creative vision.

Add camera movements to create dynamic scenes. Use zoom, pan, or auto camera for professional effects.
