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.

Method and system for composing a video material

A video processing device which generates motion metadata for encoded video comprises a decoder configured to decode frames of an encoded video into image frames; and a processing circuitry configured to execute a motion meta data deriving operation on image frames decoded by the decoder. The motion meta data deriving operation comprises: a dividing function configured to divide a current image frame into a mesh of cells, wherein each cell comprises multiple image pixels, a comparison function configured to determine a metric of change for each cell by comparing pixel data of each cell with pixel data of a correspondingly positioned cell of a previous and/or subsequent image frame, and a storing function configured to store the metric of change for each cell as the motion metadata related to the current image frame.
