Under the dual development of technology application and theoretical research, studies on teacher video learning have become increasingly mature with corresponding theoretical reserves and application experiences. Based on 59 studies on teacher video learning, this paper summarizes four types of videos in teacher video learning: focused video, integrated video, scripted/analog video, and 360˚ panoramic video. Then, it summarizes three types of video applications in teacher video learning: video-based focused instructional investigation, virtual instructional practice, and video-based facilitated instructional coaching. On this basis, three inspirations for teachers' video learning are summarized: vision guidance: "lens" layout and "angle" setting, practice approximation: "virtual" and "simulated" field creation, and facilitation: "focus" maintenance and "atmosphere" construction.
