When a file is compressed too much, the software groups pixels together, creating blocky squares.
Cheap mosaic reduction processes each frame in isolation. When played back, the "reduced" area jitters or shimmers. A better solution uses temporal smoothing, looking at frames 1, 2, and 3 to ensure the reduction stays stable during motion.
