HeyGen Official Updates Avatar IV with Lip Sync, Gesture Control, and Single Photo-to-Video AI Features

HeyGen Official has released a major update to its Avatar IV software, enhancing its capabilities for AI-driven filmmaking. The new version builds on its previous lip-sync technology by adding gesture control that responds directly to scripted prompts, enabling avatars to talk, move the camera, and incorporate visual effects. The software can transform a single photo into a talking video featuring voice synchronization, micro-facial expressions, full-body motion, and prompt-controlled gestures. This update marks a significant advancement in avatar realism and interactive control, pushing the technology closer to the uncanny valley and expanding creative possibilities for professional filmmakers.
