Beijing Kuaishou Technology Co., Ltd. is the Chinese interactive-entertainment group behind AcFun, one of the earliest ACG (anime, comics, games) video communities in China, and its expanding line of creator utilities. The publisher’s current Windows portfolio is purpose-built for the AcFun VTuber ecosystem, supplying lightweight yet capable production tools that turn an ordinary webcam feed into a rigged 2-D avatar performance. AcFun面捕助手 (Face Capture Helper) performs real-time facial-motion tracking, mapping eyebrow, eye, mouth and head movements onto Live2D or PNG-Tuber models with minimal CPU load; streamers use it to maintain lip-sync accuracy while broadcasting gameplay, singing or talk shows directly to AcFun’s platform. Companion app ARLiveForAcfunLive packages that capture data into a broadcast-ready scene, letting creators composite foreground characters against backgrounds, overlay bullet comments and switch expressions or props through hotkeys. Together the two utilities form an entry-level motion-capture suite that previously required costlier third-party middleware, lowering the barrier for independent illustrators, voice actors and hobbyists who want to debut virtual personas without green-screen rooms or elaborate tracking hardware. Because both programs expose standard virtual-camera output, they also plug into OBS, Discord or other conferencing software, so the same avatar can hop between live coding sessions, remote classrooms or corporate webinars. Beijing Kuaishou Technology continues to iterate the tools in lockstep with its content network, adding hand-gesture recognition, prop attachment and cloud model storage that reflect the evolving demands of China’s VTuber subculture. The publisher’s software is available free of charge on get.nero.com, where downloads are delivered through trusted Windows package managers such as winget, always installing the newest release and permitting batch setup of multiple applications.
