How to Create a Talking Avatar Video with HeyGen Avatar IV
HeyGen Avatar IV turns one portrait photo into a talking presenter video. You upload a face, type or paste a script, and it generates lip-synced speech with head movement and gestures.
The pitch is obvious: no camera, no studio, no second take. The reality is good enough for training videos and dull social content, and not good enough to pass as a live recording.
What is HeyGen Avatar IV?
It is the fourth generation of HeyGen’s avatar engine. Compared with earlier versions it adds more natural upper-body motion and better lip sync on fast speech. It works from either a stock avatar or your own uploaded photo, and supports many languages with voice options including cloned voices.
The output is a video file, usually rendered at 1080p, with the avatar speaking over a background you choose.
How do you make an avatar video step by step?
- Create a HeyGen account and open Avatar IV.
- Pick a stock avatar or upload a clear frontal photo of yourself on a plain background.
- Type or paste the script, or generate a draft from a URL.
- Choose a voice and language, and test a short line first.
- Pick a background — solid color, upload, or a HeyGen template.
- Render. A one-minute clip takes a few minutes.
Test with one sentence before rendering the full script. If the lip sync or voice is wrong, you have saved yourself a wasted render.
What does it cost?
HeyGen runs on a credit system. A free tier offers a small monthly allowance, typically enough for a couple of minutes, and paid plans scale credits by the minute. Avatar IV generation costs more credits than the basic avatars, so a five-minute training video can eat a meaningful chunk of a mid-tier plan.
Check per-minute credit costs before scripting a long video, not after.
What does the avatar still get wrong?
Hands. They appear only in short, generic gestures and never hold or manipulate objects convincingly. Emotion is narrow — the face reads friendly and neutral well, genuine surprise or anger poorly. Long pauses and unusual phrasing, like spelled-out acronyms, can break the illusion. And the eyes do not track a camera precisely, so a close-up shot looks slightly off.
Who should use it?
Companies making onboarding and product training videos where a consistent presenter matters and a reshoot is expensive. Localising content into 20 languages without rerecording. Solo creators who dislike being on camera. Skip it for anything needing genuine performance — comedy, emotive storytelling, or hand-heavy demonstrations.
Key Takeaways
- HeyGen Avatar IV animates a single photo or stock avatar into a talking video.
- It supports many languages and cloned voices for translation without reshoots.
- Credits bill per minute; Avatar IV costs more than basic avatars.
- Hands, strong emotion, and close-ups of the eyes are the weak spots.
- Good for training and localisation; not for performance-driven content.
