5 Steps to Add Gestures to AI Avatars with HeyGen
Follow these five simple steps to create expressive, natural-looking AI avatars:
1. Record gesture-ready footage
HeyGen’s Gesture Control is available with its Hyper Realistic Avatars – personalised avatars created using your own video footage. These avatars look just like you, as if digital twins.
Now, to add gestures to your AI avatars, start with a clean, structured video. HeyGen works best with a footage that begins with 30 seconds of neutral, no-gesture speaking. Then, you can add one gesture every 2 seconds – a smile, a thumbs-up, a point – always returning to neutral in between.
HeyGen learns from this structure, capturing your movement with accuracy and nuance. You can include facial expressions, body language, or even something like a pet walking behind you.

2. Upload video to HeyGen
Once your video footage is recorded, head to HeyGen and upload it to create your Hyper Realistic Avatar. The platform then processes your video and builds your avatar. In a few minutes, you get an avatar that mirrors your appearance, and now, your expressions and gestures as well. You don’t need any other special equipment or software.
3. Annotate gestures in Studio with HeyGen’s Gesture Control
Gesture Control will automatically detect gestures and suggest placements after the video footage is uploaded. You can review, add, and fine-tune each gesture in HeyGen’s Studio. It enables you to adjust timings and manually add and remove gestures in the footage.
When you add or update a gesture, allow 3-5 minutes for HeyGen to process the changes. This ensures everything syncs smoothly and looks just right in your videos.
4. Sync gestures with your script
With your AI avatar and gestures ready, you can now generate new videos with genuine gestures. Just add a new script and assign gestures to specific moments as your avatar speaks. All you need to do is click on a word and choose the gesture you want to appear there. Whether it’s a smile on a greeting or a nod on a key point, syncing gestures to your script makes your video feel more real.

5. Fine-tune with smart scene cuts
To make gestures appear naturally, HeyGen requires you to insert a scene cut a few seconds before each gesture. This helps your avatar transition smoothly into the movement. Just try not to overdo it.
But frequent cuts (every 5-10 seconds) can feel jarring. For the best viewing experience, aim for a clean, natural cut every 20 to 30 seconds.
Tips for Creating Natural and Impactful Gestures for Your AI Avatars
Follow these tips for natural AI avatar gestures:
- Limit to 10 gestures per video
- HeyGen currently supports only up to 10 gestures per uploaded video. Focus on the most meaningful expressions instead of packing in too many.
- Start with gestures you naturally use
- Choose gestures you’d use in real conversations. Natural expressions keep your avatar authentic and more relatable to your audience.
- Match gestures with tone and message
- Align each gesture with the purpose of what’s being said. For example, a smile works well for a welcome message, while a head tilt may be more suitable for a question.
- Keep gestures simple and clear
- Avoid overly complex or exaggerated movements. A subtle nod or a gentle hand wave is often more effective than dramatic gestures, especially in professional or informative videos.
- Pause between gestures
- Always return to a neutral pose between each gesture. It gives each movement space to land and ensures HeyGen can process them cleanly, instead of blending one into the next.
