Step 1: Write Your Presentation Script (15 minutes)

Structure Your Content

Organize your presentation with clear sections:

Opening (10-15 seconds): Greet the audience, state who you are and what you will cover
Body (2-5 minutes): Break into 3-5 key points with transitions between each
Closing (10-15 seconds): Summarize key takeaways, provide next steps or CTA

Script Writing Best Practices

Write in conversational, spoken language — not formal essay style
Keep sentences short (10-15 words max)
Avoid jargon unless your audience expects it
Add natural pauses with commas and periods — this helps AI voices sound more human
Include pronunciation guides for unusual words: "NGINX (pronounced engine-x)"

Segment Your Script

Break the script into 30-second blocks:

Each block = one scene in your video
Shorter segments are easier to edit and re-generate
If one segment sounds off, you only need to redo that part

Pro Tip: Test your script by reading it aloud at a natural pace. A 60-second segment should contain about 150 words.

Choose the Right Avatar

Consider these factors:

Audience match: Age, gender, and appearance should resonate with your target viewers
