What's new: Meet Avatar IV

HeyGen’s new Avatar IV engine brings AI video generation to a whole new level. Here’s what’s changed:

• Full-body motion: Your avatar moves naturally — hands, posture, body shifts — just like a real presenter.
• Emotive facial expressions: The avatar’s face reacts to tone and punctuation in your script — adding lifelike expressions and micro-gestures.
• Authentic voice delivery: The voice matches your tone more accurately, making it feel like you're actually speaking to the viewer.

Together, these upgrades create videos that feel more personal, engaging, and human — without ever stepping in front of a camera.

How it works — natural & fast

The Avatar IV engine is built for speed and simplicity. Once you've created your digital twin (a one-time process), using the new motion engine is as easy as selecting it in your next video. The engine processes your script and avatar simultaneously to generate synced visuals, voice, and movement. This eliminates the need for external editing or manual syncing, cutting production time from hours to minutes.

Step-by-step: How to use it

Here’s how to try Avatar IV inside HeyGen:

1. Log in to your HeyGen account — make sure your digital avatar is already created.
2. Start a new video project — enter your script or upload your input file.
3. Select your existing digital avatar — this will remain your visual identity.
4. Choose “Avatar IV” as your motion engine — it’s now available in the dropdown menu.
5. Click Generate — let HeyGen do the rest.

That’s it — your new, hyper-realistic AI video will be rendered within minutes, ready to download or publish.

Best use cases

HeyGen’s Avatar IV is especially useful for anyone who creates repeatable video content:

• Sales teams: Create personalized intros, demos, or follow-ups without reshooting the same pitch 10 times.
• Trainers & educators: Record full courses, tutorials, or onboarding sequences once, then update scripts without re-recording video.
• Content creators: Build faceless content at scale using your avatar as a virtual host across channels.
• Support & knowledge base: Replace static help docs with dynamic walkthroughs recorded by your avatar.

Tips to get the most out of it

• Write for the camera: Keep your scripts conversational and clear — the avatar will pick up on tone and flow.
• Use stage directions: Add notes like “smile,” “pause,” or “look surprised” — the engine adapts expressions accordingly.
• Batch your videos: Record multiple short videos in one go — easy to manage and publish on social.
• Combine with AI tools: Use ChatGPT to write your script, and Veo 3 or Photoshop AI for post-production assets.

Why it matters

HeyGen’s Avatar IV is a breakthrough for anyone who relies on video communication. It removes the bottlenecks of traditional video — lighting, cameras, scheduling, editing — and replaces them with a simple, scalable solution that feels personal and real. This is especially powerful in a remote-first world. Your avatar can now speak on your behalf, at scale, across languages, platforms, and time zones — while still feeling like you.
