The “Consistent Character” Protocol: Solving AI’s Biggest Narrative Flaw

I’ve spent the last six months trying to make a 10-minute short film using AI, and I’ll be honest: it almost drove me insane. The “magic” of AI video disappears the moment your protagonist changes their shirt, hair color, or facial structure between shots. I remember yelling at my monitor, “He was wearing glasses in the last scene!” This lack of Temporal Consistency is the wall where most AI creators give up. But at Arab Seed News, we’ve developed a protocol that changes everything.

The Science of Seed-Locking and LoRA Training

To make a movie, you need a “Cast,” not a series of random faces. In 2026, the secret to professional AI filmmaking isn’t just a better prompt; it’s Parametric Anchoring.

When you use high-end models like Sora 2 or Runway Gen-3, the AI starts every frame with a “Seed”—a random starting point. If you don’t control this seed, the AI “hallucinates” new details every millisecond. To solve this, we use a combination of LoRA (Low-Rank Adaptation) models and ControlNet. A LoRA is essentially a “mini-brain” you train on a specific character’s face. By feeding the AI 20-30 photos of a real person (or a consistent AI character), you force the model to prioritize that specific identity over its own random generations.

How-to: The Arab Seed Consistency Workflow

If you want to produce a coherent story, follow this step-by-step technical guide:

1. Identity Anchoring: Use a tool like Midjourney or DALL-E 3 to create a “Character Sheet” (front, side, and back views of your character).

2. The Reference Image (IP-Adapter): In your video generator, use the “IP-Adapter” feature. Upload your character sheet. This tells the AI, “Whatever motion I ask for, use this person’s geometry.”

3. Prompt Weighting for Clothing: Always specify clothing in every prompt with high weights. Example: (wearing a weathered brown leather jacket:1.5). The “1.5” tells the AI this is a non-negotiable detail.

4. The “Fixed-Seed” Technique: When generating a sequence of shots in the same room, keep the seed number identical. Only change the “Motion Prompt.” This ensures the background furniture and lighting stay locked in place while the character moves.

The Pro Insight: AI filmmaking is 10% prompting and 90% “Data Wrangling.” If you master consistency, you aren’t just an “AI User”—you are a Technical Director.
