OmniHuman 1.5 is an AI video generation platform that turns a single photo and voice recording into a film-grade digital human video with realistic lip sync, emotion, and cinematic motion. Users upload a clear portrait image, add a voice clip or music, and the system automatically generates lifelike performances, including talking, singing, and expressive gestures. The platform supports multi-person scenes and fine-tuning via simple text prompts, while maintaining consistent appearance and motion. Videos can be used for storytelling, virtual hosts, animated characters, music performances, and creative content, all generated in minutes without advanced editing skills.
