SadTalker (14,005 stars) turns one portrait plus audio into a talking-head video with lip sync - the standard for explainer videos and news avatars. LivePortrait (18,881 stars) does real-time expression and head-motion animation, great for streaming and games. Both run on a single GPU and output standard video formats.
