Proper motion blur is bidirectional, from a freeze-frame you can only tell the axis the object is moving along (parallel to the escalator) but you can't determine the direction (up or down the escalator). Unless the picture was taken with an actual camera that has known quirks that give you more information, like rolling shutter or something similar.

    Well, I don't really remember seeing motion blurred pictures.
    Only saw motion blur in games, so I guess that part I am not good at.

    But last I tried applying motion blur in an image editor (it was Paint.NET iirc), it was pretty unidirectional.
