Talking Photo or Another Kind of Video?
Choose the tool based on what should drive the scene: a spoken message, an imagined action, or a recorded performance.
Use speech to drive a portrait
Choose the avatar generator when you already know the words the person should say. The audio provides the spoken timing while the picture defines the speaker.
Use motion to drive a scene
For a walk, a turn, or an action sequence, start with the video generator. For a particular dance or gesture from footage, use motion control with a character image and reference clip.
