Here is a comprehensive guide to maximizing your Veo video output, combining high-level cinematic theory with practical, in-app directives.
The Core Prompt Structure
The most effective prompts follow a clear hierarchy. Begin with a concise, descriptive paragraph and follow it with technical specifications.
Crafting a Detailed Prompt
Subject & Character Consistency: Since Veo has no "memory" between prompts, detailed character descriptions are critical for consistency. Focus each prompt on a single, clear action and use negative prompts to refine your output.
Advanced Workflow and Strategy
Iteration is key - start with a simple concept and progressively add details. Understand Veo's limitations (5-8 second clips) and plan your story in short, interconnected segments. Use the "one beat strategy" - focus each prompt on a single, clear action to avoid confusing the model. Use reference images and explicit instructions for best results.
Input Methods & Strategies
Veo 3 supports multiple input methods for precise control:
- Text Prompts - Detailed descriptions for subject, action, environment, and style
- Reference Images - Visual anchors for character and stylistic consistency
- JSON Format (Preferred) - Structured parameters for camera angles, lighting, audio with enhanced consistency
- Audio Specifications - Synchronized sound, ambient noise, music, dialogue
- Negative Prompts - Specify elements to avoid in generated output
JSON Workflow: JSON is an alternative format that replaces text prompts entirely. Create structured JSON with scene, camera, lighting, and audio parameters → Input as complete prompt → Generate video with precise technical control.
Sample Prompt
A young detective, defined by their tired eyes and a distinctive mole under their right eye, slowly walks down a dimly lit alley at night. The scene is cinematic, film noir, and gritty. Camera: a tracking shot with a shallow depth of field, captured on a Sony VENICE. Lighting: moody chiaroscuro from a single flickering neon sign. Film: a Kodak 2383 LUT, with a high amount of film grain. Audio: the echo of distant sirens, the crunch of footsteps on wet pavement, and a haunting, jazzy saxophone riff in the background. Dialogue: "The city never sleeps. Neither do I."
