Editing Basics

Editing is part of the post-production of a film. Usually, it begins immediately after principal photography, when all the shots are recorded. The resulting footage is given to the editor and his team. By then, the director’s favorite takes would be circled in the camera report, a document also given to the editor to help him choose the best takes.

Editing is the art of  assembling shots together to tell the visual story that is films. An editor is an important crew member in any film because he will give final shape to the project. They are called the third storytellers of a movie because, after the writer and director, the editor will construct (or de-construct) the narrative and truly define the story that audience will see.

Here is how Alfred Hitchcock explains some of the fundamentals of editing:


14535 Minutes of Footage

The job of an editor is much more than cutting and splicing footage. Walter Murch, the acclaimed Academy-Award winning editor and sound designer, whose body of work includes The English Patient (1996) and The Godfather (1972), opens his book In The Blink of An Eye by sharing his nightmarish experience while editing Apocalypse Now (1979).

In that picture, Murch faced an intimidating 95:1 ratio, meaning that for every minute of footage used in the final cut of the movie, there were 95 minutes not used.

Therefore, considering that Apocalypse Now’s theatrical release runs for 153 minutes, this means that the total footage was about 14535 minutes or 242 hours long! With that abnormally extravagant quantity of footage, Murch’s primary task of scrutinizing the footage to determine what worked and what didn’t was exponentially bigger. All editors go through this same process, but usually in a minor scale.

The Film Historian’s Insight

At the end of the 19th century, during cinema’s infancy, films had no cuts or editing whatsoever. The camera ran for as long as the film reel was. During screening, the 1-reel footage was shown in its entirety to a paying audience. Soon, viewers got bored. The static image was tedious.

Editing was the solution. Edgar S. Porter, an early film pioneer, experimented heavily on the two main principles of editing: ellipsis and cross cutting. Both techniques contributed for his achievements with the movies Life of an American Fireman (1903), The Great Train Robbery (1903) and Dream of the Rarebit Fiend (1906).

 Each frame counts. The addition or removal of one frame may break or make a scene, by supporting or shattering the illusion intended. Therefore, editors work diligently to maintain the viewers’ suspension of disbelief.

Quentin Tarantino on film editing:

“For a writer, it’s a word. For a composer or a musician, it’s a note. For an editor and a filmmaker, it’s the frames. The one frame off, or two frames added, or two frames less… it’s the difference between a sour note and a sweet note. It’s the difference between a clunky clumsy crap and orgasmic rhythm.”

Film editing determines pace and structure; it is a vital component to tell stories well.

What To Do To Be a Film Editor?

An editor has to have a good instinct for the length of each shot. As Tarantino mentioned, a few frames off can make a difference.

A great way to be aware of the length of shots is to watch a film you like on mute. Without sound and music to hide the cuts, you will get to experience each and every cut in a way you hadn’t before. And that’s important because cuts is what editors do. Also ask yourself why did the editor made a cut when he did it. What was he trying to convey or provoke? You will soon notice that a horror scene is cut differently from a humorous scene.

And remember: making the cut is easy. The hard part is knowing where the cut goes.

Because the editor is dealing with images and selecting the strongest footage, he also has to understand the basics of cinematography,  specifically shot sizes. Reaction shots, for instance, can make a scene stand out like it’s nobody’s business. It’s your job to know where to insert them, and for how long.

Additionally, an editor has to be computer savvy and incredibly organized. The computer is your primary editing tool, and you will be playing with programs, codecs, file formats, and plugins to obtain your desired effects.

Two books I would recommend for you are: In the Blink of An Eye and Some Cutting Remarks. Both are from professional editors who have worked in the golden years of Hollywood. But Murch’s is my favorite because his essays on why cuts work and other topics are still relevant today.

The Cutting Edge

Here’s a great documentary about film editing. It’s over an hour long, but it’s quite insightful:

One of my favorite takeaways from the film is when Steven Spielberg explains the disagreements he had with his editor, Verna Fields, during the post-production of Jaws. While Spielberg wanted to extended shots with the shark, Fields was in favor of shortening anything with the beast. Ultimately, Spielberg agreed that Fields was right. The point here is how directors can have their minds clouded by working on the set. Spielberg had invested so much time and effort on the shark that he wanted more screen time for it. But for the editor, none of that matters. What matters is the end product because that’s what the audience will see.

    The directors in “media” field -I mean those who are responsible for some media shows and programmes- are the same as filmmakers !!!

    I wanna be an editor, too, so I can ” . . . sit in a room, talk about girls, talk, dirty, eat chocolate bars and, when the director is coming in, stand up and look like I’m doing something!” (That was such a perfect and hilarious end of the film!) After watching the informative and entertaining documentary, “The Cutting Edge: The Magic of Movie Editing,” that you embedded, I am over-the-moon excited to begin teaching my college course titled “Introduction to Digital Video Editing.” I’m teaching it because no one else stepped up; I felt badly that 17 students (would-be film editors) would be really disappointed. With very little actual film editing experience under my 67-year-old belt, I need every resource I can get my hands on to inform and inspire my students. This documentary is great because it really does describe the “magic” of the editing process. Now I (and hopefully my students) will be inspired to learn the technical aspects of the story-crafting art of editing.

      Hi Jim, thank you for stepping up to the task. I’m happy you are “over-the-moon excited” about teaching that editing course. I bet it’s gonna be a lot of fun, and no doubt those 17 students will really appreciate it.

    hi..i wanna ask, in editing we use windows 7 acer lap top can or not we do editing or we must use mac book? if can use that lap top and what software suitable for editing. Thank you.

      A MacBook is not necessary for video editing. It is true that many professionals do prefer Mac laptops, but their preferred editing software is Adobe Premiere, which is compatible with Windows PC. You do need a powerful laptop to handle the program. Good luck! 🙂
