Create Talking Character Videos from an Image
Hedra AI is a third-party product name for talking head video generation from image and audio inputs. In this workflow, you provide a source image, voice or narration audio, and prompt guidance, then get a lip-synced character video for use cases like product explainers, creator intros, and draft ad concepts. Vidu helps you test that workflow in a practical production setting.
