概要

このモデルについて

OmniHuman 2.0 animates a single portrait image with an audio track into a realistic talking or singing video. Motion and lip sync are driven by the audio, and an optional text prompt of up to 300 characters controls the scene, character motion and camera movement. It accepts audio from 4 to 300 seconds, so it suits long-form presenters, explainers and music clips, with prompts in Chinese, English, Japanese, Korean, Spanish and Indonesian.
