🎥 Introducing HeyGen AI Powered Video Creation for Everyone | Tutorial by Humanitarians AI Fellows

Creating a professional-looking video with an AI avatar sounds like it should require expensive equipment and editing skill. HeyGen is built to remove both requirements, and this tutorial from a Humanitarians AI Fellow walks through exactly how it works, start to finish.

What HeyGen actually does

HeyGen is described as a cutting-edge AI video generation platform aimed at letting individuals and businesses create professional, engaging, personalized videos without a production team. Whether the goal is a professional introduction, a project showcase, or a social media clip, the platform is built to turn a script and a chosen avatar into a finished video with lifelike delivery. There's a free plan available for getting started, with paid subscriptions unlocking more advanced features for anyone who needs them.

Getting oriented before you start

Before diving into video creation, HeyGen asks new users to define a purpose and describe their audience. That information shapes which templates the platform suggests, so the recommendations you see are tailored to what you're actually trying to make rather than generic.

Building the video: templates, scripts, and voice

The hands-on walkthrough starts by selecting a template rather than building from a blank canvas. Once a template is chosen, it comes with a pre-written script that can be edited freely to match your own content. From there, voice settings offer real control: you can speed up or slow down the delivery, shift the tone from excited to serious, change the accent, and choose from a range of available voices.

Most templates are built from multiple slides, and each one can be customized independently. That means a different avatar, a different edited script section, and a different voice setting for each slide within the same video, rather than being locked into one look and voice for the whole piece.

Choosing and customizing avatars

Avatar selection works slide by slide. You can swap in a different avatar entirely, or keep the same person and choose a different look for them, giving each section of the video its own visual identity while keeping continuity where you want it. Once the script, voice, and avatars are set for each slide, the next step is previewing the video to see and hear how everything comes together before generating the final version.

Key takeaways

• HeyGen turns a script and chosen avatar into a finished AI-generated video, with a free plan for getting started.
• New users define a purpose and audience up front so the platform can suggest relevant templates.
• Scripts, voice tone, speed, and accent can all be edited per slide, not just for the whole video.
• Avatars can be changed or restyled independently on each slide within a single video.
• Previewing the video before final generation lets you check how the script, voice, and avatar choices come together.

Who this is for

This tutorial is aimed at anyone new to AI video tools who wants a practical, no-jargon walkthrough rather than a marketing overview. It's part of a series of tutorials created by students and recent graduates from the Humanitarians AI Fellows Program, who build these guides as part of learning and teaching AI skills to a wider audience.
