Film Editing

Types of Editing for Films and TV
Continuity Editing 
The process in video creation, of combining related shots, or different components cut from a single shot, into a logical sequence so as to direct the viewers attention to a story across both time and physical location.
It creates the illusion of smooth continuous action, hence the viewer will not notice the transaction between shots and their focus will be narrative driven.
Non Continuity Editing
This is when shots are miss matched to disrupt the impression of time and space. This draws the audiences' attention to the process of cutting and disturbs the illusion of 'reality'.
What is Editing Used for In Moving Image Productions 
Editing in these such productions can be used for a multitude of things such as: manipulating time, including speeding up and slowing time, compressing time and stretching time, such as a montage(for example The Rocky saga), perception of space, this creates a logical and believable space between characters or objects not sharing the same shot, and helps the audience orientate themselves, controlling rhythm and pace to control the flow of the production(e.g. high tempo action, slow tempo to create tension).
Functions of Editing for Film and Television 
Editing is used to create a narrative, it can be used to create motivational narrative, this is whats called motivational editing. It can be used to develop drama as well as providing and withholding information from the audience.
Continuity Editing 
This can be used to create continuity between two shots, it can also be used to follow the action, it can be used to change locations and finally it can be used change the time frame including the use of flashbacks. Continuity editing is the process, in film and video creation, of combining more or less related shots, or different components cut from a single shot, into a sequence so as to direct the viewers attention to a pre-existing consistency of story across both time and physical location.
Engagement      
It can also be used to engage the audience, for example: engaging the viewer, creating suspense and creating pace.
Creating Meaning 
It can be used to create meaning for example juxtaposing elements within editing, creating empathy for a character and creating bias in fiction or documentary editing.
To show that these techniques are understood I will be analyzing a number of clips showcasing a majority of editing techniques.
Battleship Potemkin realized in 1925 and directed by Sergei Eisenstein was one of the most influential silent films of its time, receiving international fame. Throughout numerous scenes Russia's social, political and economic factors play a role in shaping the so called master piece today. The Odessa Steps Sequence begins with common people cheering the sailors, but in a single moment the joy and excitement of the scene is extinguished as they are attacked from the top of the stairs. The audience is as surprised as the character of film as they too were unaware of what was happening on the other side of the staircase. We see the soldiers with Eisenstein use of Mass effect with the large group of soldiers moving closer and closer to the people. We know that what appear to be victims are commoners due to their items of clothing. The devastation was shown through Eisenstein's use of montage, a popular technique involving the soviet montage theory. Some of these shots are used to show political agitation.
Parallel Editing
Parallel editing (cross cutting) is the technique of altering two or more scenes that often happen simultaneously but in different locations. If the scenes are simultaneous, they occasionally culminate in a single place, where the relevant parties confront each other. In the scene from Way Down West cross cutting is used to make the audience feel tense and on edge. The camera shows the struggle of the main character and then the force and veracity of the waterfall. The camera gradually pans closer and closer to the waterfall showing its power and the woman's struggle as she stumbles over the ice.
The use of parallel editing in the Silence of the Lambs adds a tense feeling to the scene, the quick cuts of the murder to the police makes the audience feel just as tense and worried as the police themselves in this scene, as well as this the scene is long and drawn out to build suspense with the audience. This scene adds a layer of suspense as well helping the pacing of the narrative. It also gives the audience more in depth visual information for the narrative.
Montages 
A montage, which is a sequence of short shots that are edited into a short clip often played behind music. This technique is used to compress time, space and information. They show the audience vital information, for example, The Rocky three montage compresses months of weight and respiratory system training into only minutes of footage. This shows the audience a difference from beginning to end of Rocky's transformation, which gives the audience a perspective of the time missed as well as giving them hope of the character completing the task they need to overcome. Montages are mainly used to show a character (often a central one) over coming a problem, dilemma or task. They are widely used in the 'Rocky' and 'Creed' trilogies. They are used to show the audience that the character is physically and mentally ready for the challenge ahead.
The clip taken from Team America is much like the montage from Rocky, Rocky is mentioned in backing music mid way through the montage, however, there is one large difference between that of the two films, one is a spoof of the other. A spoof  is a comedy attempt at another creators work. They are used for the same reasons as that of Rocky, to show improvement and progress the story and character in the narrative. It is unlike a traditional montage in the ways that it is put in place to make the audience laugh as well as progress the narrative. The editing of quick cuts and jumps are used to progress the clips as well as keep the viewer entertained throughout the clip. The music used adds to the comedic effect of the scene by mentioning the practices name and referencing other works of media that have featured montages, this is not typical of a montage they are often used to add tension or dramatic effect to a scene.
