Hedra is a free AI video creator currently in beta that allows you to make videos featuring talking avatars and characters. It offers a variety of features, including audio generation, character creation, and video generation. You begin by entering text for the dialogue and choosing a voice for your character. For visuals, you can either upload an image of your character or use the text-to-image tool to create a unique character from scratch. Hedra also has a community spotlight section where you can find inspiration and remix existing creations.
