Off Book
Describing a performer who can work without reading the script because the lines have been learned. It concerns memorisation, not whether blocking, interpretation or further rehearsal is complete.
Off Camera (O.C.)
Outside the camera’s visible frame. In scripts it can identify dialogue from a character present in the scene but unseen in that shot. Exact notation conventions vary between writers and productions.
Off Screen
Anything happening outside the camera’s frame. May also be used in scripts to indicate dialogue spoken by a character who is not visible on screen (abbreviated as O.S.).
Off Stage
Outside the visible performance area in theatre, and occasionally used more loosely in screen work. It describes location relative to the staged action rather than a specific camera or sound-recording technique.
Off the Page
An informal description of a performance or reading that feels lived rather than mechanically recited. It concerns interpretation and delivery. It is not necessarily the same as being off-book.
One-er
A scene or extended piece of action presented as one continuous shot, often called a oner. It may be captured in a single take or constructed with hidden cuts, depending on the intended effect.

One Liner
A condensed shooting schedule presenting each scene in a short line of information. It helps departments see the planned order and workload across days. Included fields vary and may identify cast, locations and page counts.
On Location
Filming at a selected real-world site rather than solely on a purpose-built soundstage. Location work can still involve set construction, substantial lighting and controlled access; it does not imply documentary-style shooting.
On Set
Present at the place where filming is being prepared or carried out. It can describe a person’s location or work performed during production. Being on set does not automatically mean a take is ready.
On Spec
Creating material speculatively without a prior commission, typically in the hope of selling or using it later. A spec screenplay is an example. The phrase does not itself establish ownership or future payment terms.
On the Clock
Within the period counted as working time under the engagement’s rules. Call, breaks, travel and wrap can be treated differently by different agreements. The phrase alone does not determine the applicable pay calculation.
On the Move
An informal call indicating that people or equipment are relocating. It may refer to a small setup change or a larger move. Naming the destination and affected departments makes the instruction useful.
On-the-Nose Dialogue
Dialogue that states an idea or feeling very directly, leaving little subtext. The phrase is often used critically, although direct speech can be appropriate when it fits the character and scene.

Op
Short for operator, such as camera operator or boom operator. The department and context determine the role. It is useful shorthand only when the intended person or equipment is clear.
Open Matte
A presentation revealing more of the photographed image than a version masked to a narrower aspect ratio. The extra area may not match the intended composition and can include material outside the original framing guides.
Optical Printer
A system that rephotographs film images onto new film, allowing operations such as compositing, titles and transitions. It combines projection and camera mechanisms and was central to many pre-digital effects workflows.
Outline
A written summary of a story or script that lists major plot points, scenes, and character arcs, usually created before writing the full screenplay.
Out-take
A shot or scene not used in the final edit, often due to mistakes or alternate versions. Out-takes are sometimes released as bonus content.
Overcrank
To capture at a higher frame rate than the intended playback rate so action plays more slowly. The term comes from hand-cranked film cameras. Recording and playback rates must both be specified to describe the effect.

Overexposure
Exposure beyond the level intended for the image or recording medium. It can reduce recoverable highlight detail, although a bright-looking image is not automatically overexposed. The effect depends on the medium and processing.
Overhead
A view or plan from above. An overhead diagram shows positions of performers, camera and equipment, while an overhead shot records a top-down view. The context distinguishes a planning document from the camera angle.
Overlap (Overlapping Dialogue)
Dialogue in which people speak at the same time. It may create naturalism or tension, but affects recording and editing options. The performance, microphone coverage and desired edit are planned together.
Over the Shoulder (OTS)
A shot looking toward a subject with part of another person’s shoulder or head in the foreground. Common in dialogue coverage, it establishes a relationship between performers. Foreground size and eyeline affect the composition.
Overtime
Work falling beyond the regular hours or thresholds specified by an applicable agreement or law. Rates and calculation rules vary. It should not be defined simply as any time beyond a production’s planned wrap.
