10 On-Set Terms Every Actor Should Know Before Filming

If you're new to the world of filmmaking, stepping onto a movie set can feel like entering an entirely different universe. The lingo used on set is unique, and understanding these terms is essential for anyone wanting to work in the industry, from actors to crew members. In this article, we’ll break down some common phrases you might hear on a movie set, so you can sound like a pro the next time you're around cameras and lights. Let’s dive in!


1. Standing By

"Standing by" is a term used to indicate that things are about to happen, primarily that the cameras are about to roll for a take. It means for everyone to get ready and focus on what’s about to happen because in a second, those things are about to actually happen. It’s different to “being on stand by” which refers to a person or department ready and awaiting orders.


2. Back to Ones

"Back to ones" refers to returning to the starting position or the place where the scene originally began. In film and TV production, a scene might require multiple takes. After a take, the director or assistant director might say “back to ones” to indicate that the scene should be reset to its original position or action before filming the next take.




3. Pick Up

When you hear someone on set say "pick up," they’re referring to continuing a scene or shot from where it was left off, often after a break. This could happen after a lunch break or between different takes. A “pick up” might be used to re-film a part of the scene where there was an issue, such as a camera glitch, missed lines, or continuity errors.



4. Swinging a Lens

In cinematography, "swing a lens" refers to the act of changing or swapping out lenses on the camera to achieve a different focal length or aesthetic look. Lenses have various capabilities, from wide-angle lenses to telephoto lenses, and the decision to "swing" one lens for another is usually based on the creative vision of the director or director of photography (DP).



5. Step In/Step Off

“Stepping on” and “stepping off” are terms that are commonly used to describe when someone enters or exits a set or shooting location. Mostly referring to actors who may be called “talent” (a term slowly being phased out) as they will be most required to leave or return to set for costume, make up or prop preparations. When you hear “stepping on” or “Stepping off” it means they’re leaving or returning, respectively.



6. Hot Set

A "hot set" means that the set is in active use and must not be disturbed. If someone on set says, "It’s a hot set," it means that everything—props, lighting, and the set itself—has been arranged and is ready for filming, and no one should alter or touch anything without permission. A "cold set," on the other hand, is a set that isn’t actively in use, and changes can be made to it.



7. Cheat It

In film, “cheating” refers to making slight adjustments to the scene or performance in order to make it look better on camera. “Cheat it” could involve an actor slightly altering their position or facial expression for the shot or moving a prop just enough to ensure the visual composition looks better in the frame. It’s essentially an intentional adjustment made to improve the final product without violating the script or the scene’s integrity.



8. Slate

The "slate" is a clapperboard used to mark the beginning of a scene or take. The slate typically contains information such as the scene number, take number, director’s name, and production details. The clapperboard has a hinged arm that makes a distinct sound when snapped, which is used to sync sound and image in post-production. A typical phrase on set might be, “Mark it!” as the slate is presented before the camera. The sound of the snap is for the post production team to use and not an indication for the cast to begin their performance. The term for that is….


9. Action

"Action!" is the iconic command issued by the director to begin filming. It signals the start of a scene, and actors are expected to start performing the moment they hear it. It’s the cue for everything to go live on set, and it’s a pivotal part of the filmmaking process that tells everyone it's time to capture the magic.



Conclusion Film Set Terms

While these terms might seem confusing at first, they are an integral part of movie set communication. Understanding and using the correct terminology will help you feel more comfortable on set, and ensure smooth communication between all departments. Whether you’re an aspiring filmmaker, actor, or just a movie enthusiast, these terms are important to know and can make your time on set more enjoyable and efficient.
