What is Hedra

Hedra is an AI lip-sync video generation tool launched by the Digital Creation Lab, a research team from Stanford University. It focuses on applying artificial intelligence technology to the generation of character videos. Users can upload photos and voices of any person, and Hedra will generate dynamic videos based on these inputs, in which the character’s lip shape, expression, and posture are perfectly synchronized with the voice content. Hedra supports text and image video generation. It is currently in free public beta and provides unlimited video generation capabilities. A single video can be up to 30 seconds long (open preview version), and every 60 seconds of input can generate 90 seconds of video.
