Hedra

Talking-character video studio and multimodal inference API

AI Avatars Lip Sync Image to Video Voiceover & Dubbing

About Hedra

Hedra started as a tool for expressive talking-head and character videos driven by audio (its Character models) and now also runs a multimodal inference platform. Hedra Studio offers credit-based monthly plans for video, image and audio generation. The usage-based API covers video generation, avatars and lip-sync, upscaling, speech and LLMs. It suits creators making dialogue-driven character clips and developers who need avatar or lip-sync generation through an API.
