Systems and methods are disclosed for efficient generation and presentation of synopsis videos that include video images of multiple objects captured at various times displayed at a common time. The system may include one or more network cameras that, when a moving object is detected, record a video file for that object and provide the video file to a cloud server. The cloud server may queue video files from the one or more network cameras and, when a user requests a synopsis video of a period of time, the video files captured during that period of time may be used by the cloud server to generate the synopsis video. The cloud server may also generate a plurality of object indicators that are provided with each of several chapters of the synopsis video in a scrollable arrangement that allows the user the scroll through objects and chapters.
