Abstract: A method and system for composing a video of a course of actions along a track in an area monitored by a plurality of video cameras. A first sequence of user inputs defining the track is received. Each user input in the first sequence is associated with a time stamp and is received as an indication of a position in a map of the area being monitored. For each user input in the first sequence, video recordings from those that have a field-of-view covering the position indicated by the user input are collected. The collected video recordings are recorded in a time period starting at the time stamp associated with the user input and ending at a time stamp associated with a next user input in the first sequence or when an indication to stop the collecting is received. A video material is then composed from the collected video recordings.
