Step-by-Step: Creating Your First HeyGen Video

Step 1: Write Your Script

Keep it conversational. Aim for 130-160 words per minute (normal speech rate):

“Hi there. I’m excited to show you our new project management dashboard. In just three minutes, I’ll walk you through the key features that help teams stay on track. First, let’s look at the timeline view…”

Tips:

• Write how you speak, not how you write
• Use short sentences
• Avoid complex technical jargon
• Add natural pauses with commas

Browse HeyGen’s library:

• Filter by gender, age, ethnicity
• Preview each avatar reading a sample script
• Check their background/setting options

Step 3: Select Voice

Options:

• Avatar’s native voice: Pre-configured to match the avatar
• Voice clone: Upload 1 minute of your own voice → HeyGen clones it
• Text-to-Speech library: 300+ AI voices in 40+ languages

Step 4: Customize Background and Layout

• Select or upload a background image/video
• Add your logo (watermark position)
• Insert captions/subtitles
• Choose avatar size and position

Step 5: Generate and Download

1. Click “Generate Video”
