How to Create a Talking Avatar Video with HeyGen Avatar IV

September 27, 2026

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?

  1. Create a HeyGen account and open Avatar IV.
  2. Pick a stock avatar or upload a clear frontal photo of yourself on a plain background.
  3. Type or paste the script, or generate a draft from a URL.
  4. Choose a voice and language, and test a short line first.
  5. Pick a background — solid color, upload, or a HeyGen template.
  6. 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.
