Editing

Editing!

In a somewhat contradictory sense, editing begins some time before the first day of principal photography.

Normally, during the pre-production phase some sort of blue print is created envisaging how the visual and aural parts will assemble to make up the whole. For many filmmakers this is the storyboard, a document which imagines how every unit of action will happen in sequence thus constituting the entire visual and aural narrative.

The storyboard for many filmmakers is the edit imagined in advance. 
The storyboard thus constitutes a highly functional document, signposting key editorial techniques which are going to be put into effect in the post-production phase, such as shot-reverse-shot sequences, eye-line matches, graphic matches, super impositions, elisions etc. 

Prior knowledge that such techniques will be in operation at the editing stage, causes directors, script continuity supervisors and DOPs to give due consideration to these elements during filming. 

In order for an action match to be possible in the edit, a piece of action, filmed from different camera angles and with different shot sizes must be identically realised in each. The rhythm and pacing of the movement must be the same; position of body parts and items of costume must be the same; other mise-en-scene elements also visible in the frame must be the same. 

Inter-cutting can set up juxtaposition between parallel story lines, strengthening the impact of each by highlighting difference.
When used to draw two story lines together, this can be structured to create tension and heighten identification with a character. 
When an action match is used for inter-cutting, it can highlight parallels/ contrasts between characters in different situations. 
Eye-line matches provide insight to a character's point of focus and give clues to interior thoughts. When a character is shown in the final shot of a scene, it is often the character with whom the audience is expected to identify. 



I generally feel that the video above is a perfect example oh how to add in transition effects to make your editing look better.
