Axial cut
An axial cut is a type of jump cut, where the camera suddenly moves closer to or further away from its subject, along an invisible line drawn straight between the camera and the subject. While a plain jump cut typically involves a temporal discontinuity (an apparent jump in time), an axial cut is a way of maintaining the illusion of continuity. Axial cuts are used rarely in contemporary cinema, but were fairly common in the cinema of the 1910s and 1920s.
An axial cut can be made with the use of a zoom lens, or physically moving the camera with a crane or camera dolly. The intervening footage (as the camera moves or zooms) is then removed while editing the film. Since footage is discarded, this technique works better for static shots. If action is involved, several takes will be required to get the necessary footage.
Alternatively, a multiple-camera setup can be used, with the cameras showing the subject at different sizes. The footage from both cameras is then edited together to create the effect. As the cameras cannot occupy the same space, there will always be a slight deviation from the axis. Moving the cameras further away from the subject and using telephoto lenses can reduce the deviation.

Cut (transition)
In the post-production process of film editing and video editing, a cut is an abrupt, but usually trivial film transition from one sequence to another. It is synonymous with the term edit, though "edit" can imply any number of transitions or effects. The cut, dissolve and wipe serve as the three primary transitions. The term refers to the physical action of cutting film or videotape, but also refers to a similar edit performed in software; it has also become associated with the resulting visual "break".
History
Due to the short length of early film stock, splicing was necessary to join together segments into long-form. Actuality directors spliced together reels prior to shooting in order to record for longer periods of time. Narrative directors, on the other hand, preferred shooting for shorter lengths, editing together shot footage. In either case, film was cut (and subsequently joining the cut segments) in order to remove excess footage, focusing attention on significant elements.
Cut and fill
In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments, so minimizing the amount of construction labor.
Overview
Cut slopes are rarely created greater than a slope of two to one (horizontal to vertical dimensions). Cut sections of roadway or rail are characterized by the roadway being lower in elevation than the surrounding terrain. From an operational standpoint there are unique environmental effects associated with cut sections of roadway. For example, air pollutants can concentrate in the ‘'valleys'‘ created by the cut section. Conversely, noise pollution is mitigated by cut sections since an effective blockage of line of sight sound propagation is created by the depressed roadway design.
Fill section
Fill sections manifest as elevated sections of a roadway or trackbed. Environmental effects of fill sections are typically favorable with respect to air pollution dispersal, but in the matter of sound propagation, exposure of nearby residents is generally increased, since sound walls and other forms of sound path blockage are less effective in this geometry.
