Key Features

AI video creation
HeyGen's AI video tools handle everything from avatar generation and voice cloning to captions, translation, and turning any input into polished video.
Avatar consistency
Avatar V maintains a single, coherent identity across every video you create. The same face, the same micro-expressions, the same presence across a 30-second clip or a 10-minute course module. No drift. No artifacts. No uncanny valley.
Behavior-based avatars
Avatar V learns how you talk, gesture, and move, then generates video that's convincingly you. The same micro-expressions, the same presence, all from a single prompt.
Multiple angles
Wide shots, medium frames, and close-ups, all consistent, all from one recording. The angles that make a single avatar work across every format.
Lip-sync
Phoneme-level accuracy across every supported language. What you hear and what you see are in perfect agreement at any speed, in 175+ languages and dialects.
Editable video
Every motion element stays fully editable after generation. Adjust text, color, timing, or layout instantly in AI Studio without rendering the video again from scratch.
Motion graphics
Generate motion graphics that work as part of a cohesive narrative. Visual overlays, explanatory animations, and B-roll footage all combine to tell your story.
AI presenter footage
AI-generated presenter footage anchors every narrative. Talking heads deliver your message with natural performance, serving as the foundation of your video.
Text-Based Editing
The text-based editor makes AI video generation as easy as writing a document. Control tone, delivery, gestures, and emotion in one seamless platform built for human-first storytelling.
Video direction
Direct every word, gesture, and emotion through a text-based editor that works like writing a document. Tone, delivery, and pacing all respond to your script.
Team editing
Comments, tagging, and multi-user editing keep collaboration in one platform. Brand Kit, auto captions, and B-roll deliver finished videos without switching tools.
Video translation
AI video translation that preserves your tone, syncs your lips, and reaches global audiences across 175+ languages and dialects.
One-click translation
Upload a file or paste a YouTube link to translate videos with one click. No reshoots, no manual dubbing. Just fast, affordable localization for any creators or business.
Multilingual videos
Translate existing footage or generate multilingual avatar videos from a single script. Brand glossary and a multi-lingual player give you full control across markets.

Our Test

Hands-on notes from our editorial team.

✅ Our Test

⬇️ Signing Up

We signed up on the website through our Google account authorization. The website proposed to select the plan, and we selected a free one with monthly limits and a watermark.

⬇️Select and Customize a Template

Then we accessed a template library where we selected one to start work with. This template was a part of the “Advertisement” templates category. The website directed us to the video editor page, where the AI avatar, scripts with chapters, and text were ready. We customized some scenes on the editor page, replaced the text on the video, and then edited the scripts. We also left the avatar’s voice as default since it was the best option for this avatar.

⬇️ Submit, Wait, Export!

As the last step on the video editor page, we clicked the “Submit” button. Rendering took about 3 minutes for the 40 seconds of video. When everything was ready we viewed our new video and exported it in the MP4 format after a click on the “Download” button.
