Continuity Editing

Continuity editing maintains a sense of realistic chronology and generates the feeling that time is moving forward. 

Flashbacks or flash forwards may be used but the narrative will still be seen progressing forward in an expected or realistic way.  

-Eye-line match = we see a character looking at something off screen and then we cut to a shot of what they are looking at.

-Match-on-action= We see the character start an action in one shot and then see them continue it into the next. 

-Graphic match = When two shots are linked with a similar shape or composition of an image. 

-Shot/Reverse shot = it shows conversations and arguments. 

-The 180 Degree rule =  is the basic guideline that states that two characters in  the same scene should always have the same left or right relationships with each other. 

If the camera crosses the imaginary axis connecting the two subjects, it is called  crossing the line.
