HeyGen offers a wide selection of over 100 AI avatars representing various ethnicities, ages, and poses. Write or audio record your scripts to effortlessly generate an AI Avatar video with flawless lip-syncing in minutes!

The different avatars available on HeyGen.

All of the avatars offered by HeyGen are based on video footage using real actors, so you know that the quality and realism are at their highest. Each avatar also comes in several different outfits to match the tone of your video, whether the video is meant to come off as more professional, casual, etc.

3. Custom Avatars

HeyGen's landing page for creating a custom avatar.

With HeyGen, you can even turn yourself into an AI avatar! Take a peek at the a step-by-step video below to guide you on creating your custom avatar. You only need two things:

  • A professional camera that shoots at 4K resolution with 60 FPS.
  • A greenscreen as the backdrop.

Here are some shooting tips:

  • Keep the camera stable.
  • Ensure the environment is quiet.
  • For the best lighting, set up at least three lights: Two pointing at the greenscreen and one on the subject.
  • Ensure the lighting is even.
  • Avoid loose or messy hair, beards, jewelry, or green or striped clothing.
  • Show a range of mouth movements (while avoiding unnatural ones like sticking out your tongue) and close your mouth as you normally would. The same goes for your body; stay standing in one place.

Here is how you will record yourself:

  1. Standing 6.5 feet from the greenscreen, record yourself reciting a 2-minute speech in a loud, clear tone of voice on any topic without repeating any sentences or numbers.
  2. Pause for two seconds after every sentence and incorporate subtle head and hand movements below chest level.
  3. Do not edit the footage.

Once complete, email the footage to the HeyGen team, which will be reviewed. After approval, you can use your custom avatar repeatedly on any video you create using HeyGen.

The process takes a couple of days, and you can even upload a custom voice to be used on your avatar!

Some options don't look completely real; in some, he is wearing a black T-shirt rather than a white one. Regardless, the clothes fit him well, and this feature takes customization to the next level!

I found the script to be easy to use and well-written. It generated twelve scenes altogether, so it's generous with how much content it generates. I made some edits to create a more engaging storyline.
