## Abstract

Frame-by-frame style drift is a fundamental challenge in AI-generated visual sequences. When each frame is generated independently, subtle variations in color palette, texture treatment, contrast curves, and rendering approach accumulate into visible inconsistency. For professional pre-visualization — where sequences must maintain a coherent visual language across dozens or hundreds of frames — this drift is unacceptable.

We present our approach to art style locking — ensuring consistent visual treatment across temporal sequences. Our style library of 200+ cinematic looks is engineered for frame coherence, not single-image aesthetics.

## The Style Drift Problem

AI generation models are inherently stochastic. Even with identical prompts and similar seeds, subtle variations in how the model interprets stylistic instructions produce visible drift across a sequence:

- **Color drift:** Warm tones gradually shift cooler, or saturation levels fluctuate unpredictably between frames.
- **Texture inconsistency:** Film grain, painterly strokes, or rendering approaches change character between generations.
- **Contrast migration:** The dynamic range and tonal mapping shift, creating visible "jumps" when frames are viewed in sequence.
- **Rendering approach shifts:** The model alternates between photorealistic and illustrative treatments within the same sequence.

## Professional Art Direction Requirements

In professional production, art direction establishes a visual contract that binds the entire project. As Block (2007) articulates in "The Visual Story," every visual element — color, contrast, movement, rhythm — must serve the narrative consistently. A storyboard that changes visual style between panels communicates inconsistency rather than intent.

> "The visual components are the fundamental building blocks that a director, cinematographer, and production designer use to create the visual structure of a film. These components must be consistent and purposeful."

— Block, B. (2007). "The Visual Story: Creating the Visual Structure of Film, TV and Digital Media"

## Style Locking Architecture

Our approach treats style not as a text description but as a multi-dimensional parameter space that is locked across the generation sequence:

- **Color histogram anchoring:** The target look is set from your reference and held across every frame.
- **Texture signature preservation:** Grain patterns, brush feel, and surface treatment stay constant across frames.
- **Tonal curve locking:** The contrast and dynamic range stay uniform across the sequence.
- **Rendering mode isolation:** The generation is constrained to a single rendering paradigm (photorealistic, illustration, sketch) without cross-contamination.

## The 200+ Look Library

AIM Previz ships with over 200 cinematic look profiles, each engineered for temporal coherence rather than single-frame impact. Each look encodes the full parameter space: color science, contrast curves, grain structure, highlight/shadow behavior, and rendering approach. When a creator selects a look, every subsequent frame in the project inherits the complete visual identity.

This approach is fundamentally different from text-based style prompts like "cinematic" or "moody" — which are interpreted differently by the model on each generation. Our looks are deterministic visual specifications, not linguistic suggestions.

## Conclusion

Art style coherence is not an aesthetic preference — it is a production requirement. AI-generated sequences that drift visually between frames are unusable for professional pre-visualization. By treating style as a locked parameter space rather than a text suggestion, we achieve the frame-to-frame consistency that professional workflows demand.
