Mise-en-scène in the context of Floating signifier

The fourth wall is a performance convention in which an invisible, imaginary wall separates the actors from the audience. While the audience can see through this "wall", the convention assumes that the actors behave as if they cannot. From the 16th century onward, the rise of illusionism in staging practices—culminating in the realism and naturalism of the theatre of the 19th–century—led to the development of the fourth wall concept.

The metaphor relates to the mise-en-scène behind a proscenium arch. When a scene is set indoors and three of the room's walls are depicted onstage—forming what is known as a box set—the "fourth" wall lies along the line (technically called the proscenium) dividing the stage from the auditorium, effectively where the audience sits. However, the fourth wall is a theatrical convention, not a feature of set design. Actors ignore the audience, focus entirely on the fictional world of the play, and maintain immersion in a state that theatre practitioner Konstantin Stanislavski called "public solitude" —the ability to behave privately while being observed, or to be "alone in public." This convention applies regardless of the physical set, theatre building, or actors' proximity to the audience. In practice, actors often respond subtly to audience reactions, adjusting timing—particularly for comedic moments—to ensure lines are heard clearly despite laughter.

Coppélia (sometimes subtitled: La Fille aux Yeux d'Émail (The Girl with the Enamel Eyes)) is a comic ballet from 1870 originally choreographed by Arthur Saint-Léon to the music of Léo Delibes, with libretto by Charles-Louis-Étienne Nuitter. Nuitter's libretto and mise-en-scène was based upon E. T. A. Hoffmann's short story Der Sandmann (The Sandman). In Greek, κοπέλα (or κοπελιά in some dialects) means young woman. Coppélia premiered on 25 May 1870 at the Théâtre Impérial de l'Opéra, with the 16-year-old Giuseppina Bozzacchi in the principal role of Swanhilda and ballerina Eugénie Fiocre playing the part of Frantz en travesti. The costumes were designed by Paul Lormier and Alfred Albert, the scenery by Charles-Antoine Cambon (Act I, scene 1; Act II, scene 1), and Édouard Desplechin and Jean-Baptiste Lavastre (Act I, scene 2).

The ballet's first flush of success was interrupted by the Franco-Prussian War and the siege of Paris (which also led to the early death of Giuseppina Bozzacchi, on her 17th birthday), but eventually it became the most-performed ballet at the Opéra.

The substitution splice or stop trick is a cinematic special effect in which filmmakers achieve an appearance, disappearance, or transformation by altering one or more selected aspects of the mise-en-scène between two shotswhile maintaining the same framing and other aspects of the scene in both shots. The effect is usually polished by careful editing to establish a seamless cut and optimal moment of change. It has also been referred to as stop motion substitution or stop-action.

The pioneering French filmmaker Georges Méliès claimed to have accidentally developed the stop trick, as he wrote in Les Vues Cinématographiques in 1907 (translated from French):

Offline editing is the creative storytelling stage of filmmaking and television production where the structure, mood, pacing and story of the final show are defined. Many versions and revisions are presented and considered at this stage until the edit gets to a stage known as picture lock. This is when the process moves on to the next stages of post-production known as online editing, color grading and audio mixing.

Typically, during offline editing, all the original camera footage (often tens or hundreds of hours) is digitized into a non-linear editing system as a low resolution duplicate. The editor and director are then free to work with all the footage on assembly, creating a rough cut, and a final cut. Editing the copy allows multiple story and creative possibilities to be explored without affecting the camera original film stock or video tape. Once the project has been completely offline edited, the low resolution footage is replaced with the original high resolution media, or brought online.
