Various implementations relate to processing pictures. In one particular implementation, a cropped picture is accessed. The cropped picture has been cropped, using a virtual camera window, from a picture in a sequence of pictures. Motion blur is generated for a feature in the cropped picture based on a motion of the virtual camera window and a motion of the feature. The generated motion blur is added to the feature in the cropped picture. In another particular implementation, a signal or signal structure includes a picture section for a cropped picture that has been cropped, using a virtual camera window, from a picture in a sequence of pictures. The signal or signal structure also includes a motion section for an indication of a motion of the virtual camera window.
