The new AI algorithm "Liveportrait" by a Chinese research team is currently making the rounds on social media, as it enables the animation of images and videos of faces based on a video recording of a face. Thankfully, the researchers have not only published a
 LivePortrait transfers both facial expressions, including eye and eyebrow movements, as well as slight head movements and lip movements - the latter being extremely useful for the realistic animation of speaking faces.  Especially in combination with AI-generated images and videos, LivePortrait offers filmmakers completely new and long-desired possibilities of control: using their own input video, facial expressions in an image or video can be controlled with precision. These animated faces give AI videos a much more realistic appearance than before. Interestingly, animal faces can also be animated with its help.  The algorithm was developed by researchers from the Chinese Kuaishou corporation, which recently released its attention-grabbing  video AI Kling. Therefore, it is expected that LivePortrait will soon be integrated into Kling as well.  The researchers provide several practical tips for using your own control videos. These should have an aspect ratio of 1:1 (e.g., 512x512 or 256x256 pixels), and you should enable automatic cropping with --flag_crop_driving_video. Additionally, ensure that the video mainly shows the head area and that shoulder movements are kept to a minimum. The first image should be a frontal face with a neutral expression. Various users have already produced demo clips using LivePortrait&s capabilities, including on Twitter:
