OpenH264 uses block-matching motion vectors to describe how a macroblock moves from frame to frame. In the episode, the protagonist reverse-engineers the video stream and discovers that the motion vectors for a fleeing car point toward the camera, while the visual pixels show it moving away. This inconsistency—a mismatch between metadata and appearance—cracks the case.
