What is Omnihuman ?

OmniHuman is an AI framework developed by Bytedance (the company behind TikTok) that generates realistic human videos from a single image and motion signals like audio or video.

It utilizes a diffusion transformer-based model and a mixed training strategy to achieve high-quality results across various scenarios, including different body proportions, poses, and interaction with objects.

Key features of OmniHuman include:

• Single image input: It can generate videos from just one image of a person, regardless of aspect ratio or body proportions.
• Multimodal motion conditioning: It can use audio, video, or a combination of both to drive the motion in the generated videos.
• Realistic video generation: It produces high-quality, lifelike videos with accurate lip syncing and natural body movements.
• Flexibility: It supports various portrait styles, including face close-ups, half-body, and full-body shots.
• Versatility: It can handle both talking and singing, as well as human-object interactions and challenging body poses.

OmniHuman has the potential to revolutionize various fields, including virtual influencers, film production, and digital content creation.
