Add a Human Touch: Creating Talking-Head Course Videos with HeyGen

A presenter on screen makes a course feel personal — but not everyone wants to film themselves, set up lighting, or re-record every time the script changes. HeyGen is an AI video tool that creates talking-head videos with a presenter and voiceover from a script you type, which you can then add to your CourseConverter courses.

What HeyGen does

HeyGen turns a written script into a video of a presenter speaking it. You choose an AI avatar — a stock presenter, a photo brought to life, or a "digital twin" you create from a short clip of yourself — type or paste your script, pick a voice and language, and HeyGen generates the video with synced speech. No camera, no editing, and when your script changes you simply regenerate.

Why this is useful for courses

A talking-head intro or module explainer adds warmth and presence that text and images alone can't. With HeyGen you can produce that presenter-led feel without the production overhead, keep a consistent presenter across an entire course, and update a video by editing the script rather than re-shooting. It also supports many languages, which is handy if you localise courses.

How to use a HeyGen video in your course

1. Write your script — keep each video focused on one idea or section, the same way you'd structure a module.

2. In HeyGen, choose an avatar and voice, paste your script, and generate the video.

3. Download the finished video as an MP4. For the widest compatibility, especially on mobile, make sure it's H.264 video with AAC audio.

4. Host the video somewhere with a stable link — a service like Bunny.net works well (see our guide on hosting videos).

5. In your CourseConverter course, add a video block and paste the video's URL.

A few honest things to know

Check the plan and any limits. HeyGen offers a free plan as well as paid tiers. Free plans on AI video tools often have limits on length, number of videos, or may add a watermark. Check HeyGen's current pricing and what the free plan includes before you build a whole course around it.

Only create avatars you have the right to use. If you make a "digital twin" or photo avatar, use your own likeness or someone who has clearly consented. Don't create an avatar of someone without permission — it's both an ethical and a legal issue.

Use AI presenters honestly. AI avatars are convincing. For training and education, it's good practice not to mislead learners into thinking an AI presenter is a real person if that distinction matters in your context.

Keep videos short. The same course-design principle applies: a focused two-minute explainer beats a ten-minute monologue. Script tightly.

The bottom line

HeyGen lets you add a presenter-led, voiceover video to your courses without filming anything — write a script, generate the video, host it, and embed it with the video block. Check the plan limits, only use avatars you have the right to, and keep each video short and focused.
