Diegetic Sound -
Sound whose source is visible on the screen or whose source is implied to be present by the action of the film:
- voices of characters
- sounds made by objects in the story
- music represented as coming from instruments in the story space
Diegetic sound is any sound presented as originated from source within the film's world Digetic sound can be either on screen or off screen depending on whatever its source is within the frame or outside the frame.
Another term for diegetic sound is actual sound.
Throughout this clip diegetic sound is used, all of what the audience hears is real sound and is present on set.
Visual Effects - These
are traditionally divided into the categories of optical effects and mechanical effects. With the emergence of digital film-making tools a greater distinction between special effects and visual effects has been recognized, with "visual effects" referring to digital post-production and "special effects" referring to on-set mechanical effects and in-camera optical effects.
In this clip at 1:15, visual effects are used and they create creatures that aren't real but appear in the shot as if they are present in the scene.
Post-Production - This
is part of filmmaking and the video production process. It occurs in the making of motion pictures, television programs,radio programs, advertising, audio recordings, photography, and digital art. It is a term for all stages of production occurring after the actual end of shooting and/or recording the completed work.
Ellipsis - This
is both a narrative device and the most basic idea in film editing. Ellipsis concerns the omission of a section of the story that is either obvious enough for the public to fill in or concealed for a narrative purpose, such as suspense or mystery.
Slow Motion - This
is achieved when each film frame is captured at a rate much faster than it will be played back. When replayed at normal speed, time appears to be moving more slowly. The technical term for slow motion is overcranking which refers to the concept of cranking a handcranked camera at a faster rate than normal.
Throughout this clip there is a use of slow motion shooting. This adds effect and gives the audience more of an interest in the shot.
Superimposition -
The superimposition of one thing over another in the same shot. Sometimes tiles are superimposed over scenes. Or a face can be superimposed over a stream-of-consciousness montage shot.
In this clip, at 0:11, an superimposed image of the tardis spinning is put in the shot.
Wipe - This
is a type of film transition where one shot replaces another by travelling from one side of the frame to another or with a special shape. If the wipe proceeds from two opposite edges of the screen toward the center or vice versa, it is known as a barn door wipe (named for its similarity to a pair of doors opening or closing).
