AI Video Scripts: How to Write Scripts That Work with AI Avatars

Why Scripts Matter More for AI Video

With real video, a skilled presenter compensates for mediocre scripts. They add energy, interpret tone, and adapt in the moment.

AI avatars can't do this. They deliver exactly what you write, nothing more. A poor script produces a poor video—every time.

This makes scriptwriting the highest-leverage skill for AI video success.

Fundamentals of AI Avatar Scripting

Write for Speech, Not Text

People speak differently than they write. AI scripts must sound natural when spoken aloud.

Written text style (don't use): "The implementation of our comprehensive solution facilitates the optimization of your organizational workflow processes."

Spoken style (do use): "Our tool makes your work easier. It handles the tedious stuff automatically, so you can focus on what matters."

Quick test: Read your script aloud. If it sounds stiff or unnatural, rewrite.

Keep Sentences Short

AI handles short, clear sentences best. Long sentences create:

• Unnatural pacing
• Lip-sync challenges
• Viewer confusion

Guidelines:

• Average sentence: 10-15 words
• Maximum sentence: 25 words
• One idea per sentence

Example:

❌ "When considering the various options available for your video marketing strategy, it's important to evaluate how AI-powered solutions can provide significant cost savings while maintaining quality."

✅ "Let's talk about AI video marketing. You can save 70% on production costs. And the quality? Often better than traditional methods."

Add Natural Pauses

Without explicit pauses, AI delivers content as continuous speech. Add breathing room:

Pause markers:

• Ellipses (...) for brief pauses
• Commas for micro-pauses
• Period + new sentence for longer pauses
• [pause] for explicit direction (platform-dependent)

Example with pauses:

"Here's something most people miss... The biggest factor in video success isn't quality. It's consistency."

Use Contractions

Contractions make speech sound natural:

• "you're" not "you are"
• "it's" not "it is"
• "don't" not "do not"
• "we've" not "we have"

The exception: emphasis. "This is NOT optional" works better than "This isn't optional."

Script Structure for AI Video

The Hook (0-3 seconds)

First impressions determine whether viewers watch or scroll. AI avatars deliver hooks effectively because they're typically short and punchy.

Hook Types That Work:

Question hooks:

• "Ever wondered why some videos go viral?"
• "What if you could create 100 videos in a day?"

Bold statement hooks:

• "Most video marketing advice is dead wrong."
• "Forget everything you know about content creation."

Pain point hooks:

• "Tired of spending hours on video production?"
• "If content creation feels overwhelming, listen up."

Statistic hooks:

• "93% of marketers say video is essential. But only 30% do it consistently."

Direct address hooks:

• "You're about to learn the exact process top creators use."

Keep hooks under 10 words when possible.

The Promise (3-10 seconds)

Tell viewers what they'll gain by watching:

• "In the next 60 seconds, you'll learn..."
• "By the end of this video, you'll know exactly..."
• "I'm going to show you three ways to..."

Be specific. Vague promises lose viewers.

The Body (Main Content)

Structure options:

Numbered lists:

• "First..." "Second..." "Third..."
• Clear progression, easy to follow

Problem → Solution:

• State the challenge
• Present the answer
• Explain how it works

Story structure:

• Situation
• Complication
• Resolution

Comparison:

• Old way vs. new way
• Before vs. after
• Option A vs. Option B

The Call to Action (Final 5-10 seconds)

Effective CTAs for AI avatar videos:

• "Click the link below to..."
• "Try it free at..."
• "Subscribe for more..."
• "Comment your biggest question below."
• "Visit [URL] to get started."

One clear CTA beats multiple competing asks.

Platform-Specific Script Optimization

TikTok / Instagram Reels / YouTube Shorts

Length: 15-60 seconds (40-150 words)

Format:

• Hook in first 1-2 seconds
• Fast pacing
• Single focused point
• Strong visual hooks
• Trending sounds/formats adapted

Script template:

[Hook - 2 sec] One sentence that stops the scroll.
[Setup - 5 sec] Quick context.
[Main point - 20-40 sec] The core message, delivered fast.
[CTA - 3 sec] What to do next.

YouTube (Standard Format)

Length: 2-5 minutes (300-750 words)

Format:

• Hook + promise first 15 seconds
• Structured sections
• Recap/summary
• Clear chapters possible

Script template:

[Hook - 5 sec] Attention grabber.
[Promise - 10 sec] What viewers will learn.
[Section 1 - 60 sec] First main point.
[Section 2 - 60 sec] Second main point.
[Section 3 - 60 sec] Third main point.
[Summary - 15 sec] Quick recap.
[CTA - 10 sec] What to do next.

Training / Educational Content

Length: 3-10 minutes (450-1,500 words)

Format:

• Clear learning objectives
• Logical progression
• Checkpoints/summaries
• Practical examples

Script template:

[Introduction - 30 sec] What will be covered and why it matters.
[Learning objective 1 - 2-3 min] Teach, example, check understanding.
[Learning objective 2 - 2-3 min] Teach, example, check understanding.
[Learning objective 3 - 2-3 min] Teach, example, check understanding.
[Summary - 30 sec] Key takeaways.
[Next steps - 15 sec] What to do with this knowledge.

Product Explainer

Length: 1-3 minutes (150-450 words)

Format:

• Problem identification
• Solution introduction
• Key features (3 max)
• Social proof
• Call to action

Technical Scripting Considerations

Pronunciation Guides

AI sometimes mispronounces unusual words. Options:

Phonetic spelling: Write it how it sounds

• "GIF" → "jif" (or "gif" depending on your preference)
• "Azure" → "azh-er"

SSML tags (platform-dependent):

• <phoneme> tags for precise pronunciation
• Check platform documentation

Avoidance: Use simpler synonyms when possible

Numbers and Dates

Write out numbers under 10:

• "three reasons" not "3 reasons"
• "seven steps" not "7 steps"

Use numerals for larger numbers:

• "over 10,000 users" (AI reads naturally)
• "93% of marketers" (clearer than "ninety-three percent")

Dates:

• "January 2026" not "1/2026" or "01/2026"
• "the fifteenth" not "the 15th" (for spoken dates)

Words to Avoid

Tongue-twisters:

• Complex consonant clusters
• Repeated similar sounds
• Unusual word combinations

Jargon without context:

• Industry terms your audience may not know
• Acronyms without explanation

Complex names:

• Foreign names without pronunciation guides
• Technical terms with unusual spelling

AI-Assisted Script Writing

Using ChatGPT/Claude for Scripts

Effective prompts:

"Write a 60-second AI avatar video script about [topic]. 
Target audience: [audience]. 
Tone: [conversational/professional/energetic]. 
Include: hook, 3 key points, call to action."

What AI writing does well:

• Generating ideas and outlines
• Creating first drafts quickly
• Structuring information logically
• Writing variations for testing

What requires human editing:

• Brand voice and personality
• Optimizing hooks for engagement
• Verifying accuracy of claims
• Cultural and contextual appropriateness

Script Testing Framework

Use AI to generate multiple versions, then test:

1. Generate 3-5 hook variations
2. Create different script structures
3. Produce videos with each version
4. Test with small audiences
5. Scale winners

This testing approach is only economical with AI video—traditional production can't iterate this fast.
