Abstract
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.
