Why This Use Case Matters in 2025

Creating a spokesperson-led ad traditionally requires hiring an actor, booking a studio, and managing a film crew—a process that is expensive and slow. As of late 2025, Invideo's "AI Avatar" (or "AI-UGC") feature allows any brand to generate a realistic, high-quality digital human to act as their spokesperson. This makes it possible to create consistent, scalable, and professional testimonial or explainer ads in minutes, not weeks.

How Invideo Simplifies Spokesperson Ad Creation

Invideo's platform is designed to generate a complete, "talking head" style video from your script, creating both the actor and the voice.

Automated Generation (Text-to-Video)

You provide a prompt that includes your script and describes your desired spokesperson and setting (e.g., "a professional-looking woman in a modern office"). The AI generates the complete scene.

AI-Generated Avatars

This is the core feature. Invideo can generate a realistic, high-resolution AI avatar to perform your script. You can choose from a library of avatars or, in some workflows, generate one based on your description (e.g., "a friendly male mechanic," "a professional doctor").

AI Scripting and Voice Performance

You can paste your own script for the avatar to perform. The AI will then generate a natural-sounding voiceover with realistic lip-syncing. You can direct the voice's tone (e.g., "professional," "friendly," "excited").

Intuitive Refinement (Text-Based Editing)

After the first draft, you can "direct" the AI actor. Use simple text commands like, "Change the avatar to a man in his 40s," "Make the background a 'library,'" or "Make the avatar's tone 'more confident.'"

Step-by-Step Workflow

Step 1: Write Your Script

Write the script you want your spokesperson to say.

Step 2: Write the Prompt

Describe the actor and the scene, and provide your script.

• Example Prompt: "Create a 30-second ad. Use a 'female AI avatar' in a 'modern office setting.' She should be 'professional' and 'friendly.' Here is her script: [Paste your 30-second script here]. End with our company logo."

Step 3: Generate and Refine

Invideo will generate the video of the avatar speaking your lines. From there, you can refine it.

• "Upload my logo and place it in the bottom-right corner."
• "Change the avatar's outfit to a 'blue blazer.'"
• "Add text overlays for the key features she mentions."
• "Make the voiceover 'slower and clearer.'"

Comparison: Traditional Workflow vs. Invideo

Factor	Traditional Method	Invideo (2025)
Timeline	2-5 weeks (casting, filming, post-production)	5-15 minutes (generation and refinement)
Cost	Extremely High (actor fees, studio rental, crew, editor)	Low (fixed subscription cost)
Skill Requirement	Professional (Director, casting agent, editor)	Accessible for any marketer (prompt-based)
Revisions	Requires a reshoot; new script is a new production	Instant and text-based; just edit the script and regenerate

Expert Tips for Better Results

• Use a Good Script: The AI avatar will perform what you write. A natural, well-written script is the most important element for a believable ad.
• Be Specific About the Avatar: Don't just say "a person." Describe your target audience: "a friendly, middle-aged doctor," "a young, energetic tech reviewer," or "a calm, professional financial advisor."
• Use Voice Cloning: For maximum brand consistency, you can use Invideo's voice cloning feature to have the AI avatar speak in your brand's specific voice.
