I have looked at some examples of how editing has been used to contract or expand time in movies.
My first example I found was in a Japanese film called Pandemonium by the Director Toshio Matsumato this is the link to the movie on YouTube
https://www.youtube.com/watch?v=yeTxQHWlQOc 00:02:37 into the movie we have a scene where he turns to look back at his pursuers, this is repeated from different angles extending the moment and emphasizing the drama.
In another movie L’homme qui ment by Alain Robbe-Grillet
https://www.youtube.com/watch?v=-wKptM19HV4 the French film begins by a man being pursued by German soldiers who are shooting at him and throwing grenades at him the in the pursuit the scene gets darker and he is shot and falls to the ground the camera stays on him and the scene brightens suggesting the passing of time from night to day. The time-code is 00:03:55 from the moment he fall at the start of the darker shot and 00:04:36 and the end of the shot which has changed to bright sunlight and he gets up unhurt. In this example use of two different shots have been used one just as he falls and the other as he lays of the forest floor. A possible change of exposure has likely simulated speeded up time. Another examples of speeding up time in this short-film is by way of cutting. We see the man walking out of the forest towards a line of trees, the film cuts to some girls playing blind-mans buff in a courtyard then we cut back to the man who appears to have now crossed the field and passed through the trees that are now behind him. Cut back to the girls now playing their game, cut back to the man now at the edge of the village, this continues as the man passes through the village the girls appear to have moved their game inside a house and so on until the man enters the house and they meet. In this example the film-maker has both compressed time and shown the audience two separate events that may or may not be happening at the same time.
Here is a good example of how time has been stretched to create an entrance for the character Johnny in Martin Scorsese’s ‘Mean Streets (1973).
