It works by processing frames of video using a block-oriented, motion-compensation-based video compression standard. Those units are called macroblocks.

Source video, consisting of a sequence of video frames, is encoded or compressed by an HEVC video encoder to create a compressed video bitstream. The compressed bitstream is stored or transmitted.
