Great News!
HeyGen now offers three free trial credits - experience top-tier AI avatar generation without subscription!
I've been using HeyGen's AI avatar tool and have been consistently impressed by its generation quality. Recently, I logged in and discovered they now offer three free trial credits - amazing! For those unfamiliar with HeyGen, let me give you a quick introduction.

What is HeyGen?
HeyGen is an industry-leading AI avatar platform. Simply upload a 1-second video or a single photo, and within 30 seconds, it creates your digital twin with precise cloning of your appearance and voice, generating 60-second videos with top-tier quality.
Demo Showcase
Let me show you two videos to demonstrate HeyGen's actual capabilities:

The results are incredibly realistic, right? Whether it's lip-syncing, facial micro-expressions, or subtle body movements - everything looks amazingly lifelike.
Key Features
- 100+ Pre-made Avatars: HeyGen offers over 100 pre-made AI virtual avatars for users to choose from
- Personalized Customization: Upload your own photos to generate personalized virtual avatars through AI technology
- Text-to-Video: Simply input text content, and HeyGen automatically generates matching animated videos with fine-tuned details like tone, speed, and lip-sync
Open Source Version
Even better, HeyGen has gone open source! Developers and businesses can now deploy the AI avatar system locally.

Local Deployment Requirements:
- GPU: NVIDIA 1080Ti or better
- Storage: At least 100GB
With these specs, you can set up your own personal avatar generation tool on your machine.
Local setup isn't suitable for most users though. For those who want to try it, you can use the official website. Below, I'll show you how to register, subscribe, and use HeyGen to create an avatar video.
How to Register a HeyGen Account
Registering for HeyGen is simple - all you need is an email and VPN access.
Click the "Login" button, then enter your email and password to complete registration.


Once registered, you can proceed to create your first avatar video.
How to Create an Avatar Video with HeyGen
Step 1: Create Video
From the HeyGen homepage, click the "Create Video" button in the top left.

Step 2: Choose Creation Method
You'll see two options:
- Avatar Video Generation: Create an avatar from video and use natural-sounding voice to read scripts
- Lip-sync Translation: Translate videos while maintaining lip-sync and preserving the speaker's original voice (essentially creating multilingual versions of your videos)

Since we're creating an avatar video, select the first option.
Step 3: Select Template
You'll find 5 options on the left:
- Start from scratch
- Use template
- Upload PPT
- AI generation
- PDF to video
We'll select the first option "Start from scratch" and choose landscape orientation.

Step 4: Create Avatar
You'll see numerous character templates, and you can also upload your own photo. Click "Create New Avatar" button on the left.

Then choose your method:
- Upload video
- Use existing avatar
- Create avatar with AI
For convenience, I simply found an image online and uploaded it.

Step 5: Edit and Generate
After uploading your avatar, edit your script, content, and other elements, then click the "Submit" button in the top right and wait for the system to generate your video.

Actual Results
Here's my generated result:
Pro Tip:
My avatar has minimal body movement because I used a still image. For more realistic results, record a 2-5 minute talking video with a solid color wall or green screen background, and use an external microphone for better audio quality.
Subscription Options
If you've used up your three free credits and want more, you can subscribe to HeyGen for significantly more usage quota.
Conclusion
HeyGen is a powerful AI avatar generation tool that works for both individual creators and enterprise users. You can quickly generate high-quality avatar videos. The three free trial credits let you experience this cutting-edge AI technology at zero cost - highly recommended!
