The 87th Academy Awards aired Feb. 22 this year. While all eyes were on the stars of movies like Boyhood, The Theory of Everything, and American Sniper, STEMers know that these movies couldn’t have been made without the people behind the scenes.

The film industry is always utilizing new technology, finding ways to create and edit that amaze audiences. Whether a science fiction flick or period drama, there are numerous positions in the film industry that require individuals who are not only creative but also have great tech skills.

Here are a few tech jobs in the film industry that you may not even know about!

Editor

The editor has the important job of putting all the pieces together. After coordinating with the director on how the film should be put together, an editor must link all the clips together in addition to creating and adding special effects to ensure the film looks seamless. An aspiring editor can work with programs like Avid, Final Cut Pro and Adobe Premier to practice.

DVD/Blu-Ray Authoring Engineer

These engineers are responsible for making the menus, as well as the bonus features such as subtitles, commentaries and other interactive elements that appear on the movie’s DVD and Blu-Ray versions. What good would those bonuses be if the buttons don’t work or they’re hard to navigate? These engineers are proficient in programs such as Adobe Encore, Apple DVD Studio, Adobe Illustrator and Photoshop.

Visual Effects

Jobs in visual effects continue to grow thanks to the emerging use of digital technology. Visual effects coordinators are the ones who make houses explode, characters appear and magic happen – all from a computer. A visual effects person has to be creative and good with a computer, but they must also understand mathematical algorithms. This way they can create realistic motion and texture, from wind blowing hair to sweat running down a cheek.

Gaffer

A gaffer is the lead electrician on set, but also monitors cameras, mics and other wireless technology  to make sure they are working effectively. Gaffers or grips are the ones required to fix these when something goes wrong.

Digital Imaging Technician

This is a new job in the film industry that emerged as digital became more widely used. This person coordinates with the cinematographer to oversee exposure, apply camera settings and ensure that the best quality image is produced. The technician may also be the one managing and transferring image data.
