What Is a Consistent Character?

Continuity is the invisible thread that holds a viewer’s attention and a production’s believability together.

This is why, on big-budget productions, the Script Supervisor—affectionately known as “scripty”— is always behind the monitor on set.

Their sole job is to ensure that character continuity remains consistent, preventing many distractions that might break the audience’s immersion.

In AI video production, a consistent character is a digital persona that maintains the same face, outfit, hairstyle, and style across every scene.

Whether you’re building a branded mascot or a protagonist for a short film, visual consistency anchors a narrative, builds emotional impact, and streamlines your workflow.

LTX Studio makes this possible in the AI video production space through its new AI Actor feature, giving users the tools to train custom AI characters using photo uploads, detailed text prompts, or predefined templates—ensuring professional-grade results across even the most dynamic sequences.

Why Character Consistency Matters in AI Video

• Narrative Cohesion: Viewers connect more deeply with characters who look, act, and evolve in ways that feel in line with how we understand them. Sudden visual changes—like mismatched faces or outfits—can break immersion and disrupt potential emotional impact.
• Brand Identity: In advertising, recognizable AI avatars and spokespeople strengthen message recall and maintain visual alignment across campaigns, platforms, and edits. This is why a green gecko, doughboy, and caveman can immediately evoke associations to specific brands. This demonstrates the power of character continuity as an effective marketing strategy.
• Production Efficiency: When character fidelity is built into the system, creators reduce errors, eliminate unnecessary re-renders, and unlock faster timelines for feedback and delivery.

Common Pain Points Solved by LTX Studio’s Actors

• Maintaining character likeness in every shot without time-consuming manual tweaks
• Reducing visual inconsistencies between scenes
• Enabling asset reusability across projects
• Accelerating storyboards and animatics with high-fidelity AI characters

How to Create Your Consistent Character with the Actor Library

Creating a consistent character in LTX Studio is a fast, intuitive process designed to meet the needs of all kinds of professionals. With just a few inputs—like a written prompt, a set of reference images, or a predefined character template—you can build a custom AI character that retains fidelity across your scenes. All characters are saved in your Actor Library, where they can be reused, refined, and seamlessly integrated into any project.

Let’s walk through each method for generating your AI actor:

Step 1: Use the AI Actor Feature

• Navigate to the Actor Library in LTX Studio (“Create an Actor” on the homescreen). 
• Select “Create Actor” to start the process.
• This tool is directly linked to other workspaces in LTX Studio, enabling continuity across projects, scenes, and animations.

Step 2: Create Your Actor (3 Options)

LTX Studio supports three distinct methods within its AI character builder for creating your custom AI actor:

Option 1: Use a Predefined Character

Choose from a library of professionally designed characters already built by LTX Studio. These are great for quick prototyping or storyboarding. This is the fastest option, and ideal for early-stage concepting.

‍

‍

Option 2: Create from a Text Prompt

Write a detailed description of your character’s appearance, including traits like age, hairstyle, outfit, demeanor, and style (ie: “30-year-old man with silver hair and a leather jacket, neutral expression, cinematic noir lighting”). When you’re ready, click “Generate images” to see your results. As always, you can iterate as needed until you find the perfect fit.

‍

‍

Option 3: Upload a Photo (Best for Realism and Control)

Upload between 5 and 12 high-quality JPG or PNG character reference photos. This option is best when precision is critical—such as for brand spokespersons, real-world talent, or continuity across episodic projects.

Tips for Uploading Actor Photos

To ensure that your AI actor is designed accurately and delivers consistent results, 

• Best Practices
  
  • Use a mix of close-ups and full-body shots
  • Capture a range of angles and facial expressions
  • Stick to clean, well-lit backgrounds (white walls, blank studio setups)
  • Use high-resolution, .jpg or .png formats
• Avoid
  
  • Photos with sunglasses, hats, or anything obstructing the face
  • Blurry, dark, or low-res photos
  • Group photos or cluttered backgrounds

Step 3: Use Your Character in Any LTX Project

Once created, your character is stored in the Actor Library and accessible via the Character Generator in any new project.

You can reuse your AI avatar across:

• Scene change and camera angles
• Dialogue moments or dubbed content
• Entire campaigns or video series

Unlock Next-Level Visual Continuity in Every Project

Developing consistent characters used to require deep technical know-how and slow, manual processes. With LTX Studio’s AI Actors, you gain scalable, intuitive tools for video continuity, greater narrative impact, and a streamlined workflow.
