Beginner-friendly guide to getting started with Google Flow and Veo 3, covering account setup, basic navigation, and your first video generation.

3. Character Consistency Techniques

Character consistency in AI-generated video content represents one of the most challenging technical problems in generative media. Veo3 introduces revolutionary approaches to maintaining character appearance, identity, and visual coherence across multiple shots.

Advanced Architectural Solutions

Veo3’s core character consistency capabilities stem from its sophisticated latent diffusion transformer architecture that employs long-range dependency modeling through self-attention mechanisms. The transformer’s ability to “look back” at latent representations of previous frames enables maintaining consistent character appearance, facial features, and clothing across temporal sequences.

Character Bible Development

Essential Components

Character: [Name] Age: [Specific age with descriptive context, e.g., “woman in late 20s with fine laugh lines”] Face: [Shape, specific features, eye color/shape, unique marks] Hair: [Color, style, texture, specific details] Body: [Build, height perception, posture] Clothing: [Detailed outfit description including materials, colors, fit, accessories]

Example Character Description

“A woman in her late 20s with long, curly auburn hair reaching her mid-back, bright emerald green eyes, and a light spray of freckles across her nose. She wears a chunky, oversized knitted sweater in a deep olive green, paired with dark grey skinny jeans and brown ankle boots with buckle details.”

Strategic Prompting Methodologies

Golden Rules:

  • Verbatim Repetition: Copy character descriptions exactly across all prompts
  • Prioritize Character Details: Make character description prominent in each prompt
  • Establish Clearly: First prompt must include all descriptive detail
  • Maintain Core Descriptors: Repeat full character description while varying only action/setting

Multi-Shot Sequence Example

Shot 1:

“[Full Character Description]. Sarah is sitting at a cluttered wooden desk, intently typing on a laptop, a concerned expression on her face. The room is dimly lit by a desk lamp. Close-up shot on Sarah’s face and the laptop screen.”

Shot 2:

“[Full Character Description – identical]. Sarah sighs, pushes back from the desk, and stands up, stretching her arms above her head with a look of frustration. The camera pulls back slightly to a medium shot, showing more of the messy room.”

Scene Builder Optimization

Google Flow’s Scene Builder functionality is designed to maintain character consistency across multiple shots within scenes. Users can add subsequent shots to timelines using ‘Jump to’ or ‘Extend’ options while preserving the same face, outfit, and general appearance.

Current Limitations

  • Character consistency quality varies significantly based on prompt detail
