using apropriate conventions

• Cutaway's  
• Cutting on Action
• Creating Juxtaposition
• Intercutting
• Pace Effectively  

Cutaways: Editors use this to add more action to part of the scene and make it more interesting. Cutaways are used in films to cutaway from the main action, to add related material or showing another object in the area of where action is happening. for instance you could have an interview to edit together, so you want it to be very interesting, the cutaway method of hiding or masking edits where you have cut out all of the uming and areing in the interview are hidden with the extra footage that you add in.
below is a video on YouTube that is very good at explaining different types of cutaways and how they can be used such as some of the examples I have previously spoken about.

 

Cutting on action is a way of preserving continuity and making cuts flow together. It helps you make your cuts invisible and draws viewers into your story. It is a very useful way to transition between shots, especially shots which may otherwise have nothing to tie them together. One common example is a person walking up to a door and reaching for the handle. Just as his hand touches the Handle is the perfect opportunity to cut to a shot of the door opening from the other side. The second shot should have a level of action equivalent to the first. The motion transitions the shots from one to another.  

 

creating juxtaposition in editing is used all of the time weather you think it or not with the edits trying to get emotions out of you and getting you to think for instance 'This was first proven in the 1920s, when a Soviet filmmaker shot an actor with an expressionless look on his face. Next he shot a bowl of soup and an injured girl. He cut to the bowl of soup and then cut back to the actor’s reaction. Then he cut to the injured girl and back to the actor’s reaction. He showed this to audiences who believed in the first shot that the actor was expressing hunger and that in the second shot he was expressing pity. In reality, the actor was looking at the camera and at no time was expressing any emotion. The audience made this determination on their own based on how the segment was edited'. (http://mediamissionaryschool.blogspot.co.uk/2011/08/juxtaposition-is-core-of-editing.html) and so by placing two shot together that don't have an immediate link you are making the audience think about what they are seeing before they judge by what they see or are 'fed' and so you are creating the juxtaposition by putting those two links together.

the link blow shows you a similar example visually of what juxtaposition looks like.

 Intercutting is the same concept as parallel editing see my post on this for more information;

Pacing the shots effectively gives the film that extra bit of a wow factor as if you have a film that has pacing issues then the audience is going to 1. feel as if they are all over the place and don't know what they are doing, this could be because it is to fast and so they are missing vital information or 2. they are going to get really board because the film is to slow  and so they are getting too much information for their liking. for instance the film The Hobbit, The Desolation of Smaug has had a few bad review on its pacing complaining that the climax of the film was brought on prematurely:

 

 'The second of Peter Jackson‘s trilogy of films adapting The Hobbit, The Desolation of Smaug, both improves on the previous film, and regresses from some of its achievements. In 2012′s An Unexpected Journey, Jackson stretched the story of The Hobbit to a breaking point. Sequences that were mere blips in the book became much longer, hurting the pacing immensely. At the start of this second film, Jackson picks up the pace considerably and, in just over an hour, our characters are at their final destination: The Lonely Mountain. Unfortunately, there’s still an hour and a half to go (plus another movie) which means that briefly improved, upbeat pace comes to a screeching halt. Plus that rushed first hour glosses over some of the most famous scenes in J.R.R. Tolkien‘s book'.

And so even the greatest films can be downgraded due to the mistakes of the editing and decision making of the production team, so this is why you have to be very careful when you are creating pace for a film.
