Filmmaking Dictionary: Number 2 / 2D Film and Video
Definition
2D means two-dimensional. In film and video presentation, it usually describes a single flat image viewed without separate left-eye and right-eye pictures. A conventional cinema screening, television programme or online video is normally presented in 2D.
The term also describes animation and graphics created primarily on a flat plane. These are related uses, but they are not interchangeable: a film made with three-dimensional computer models can still have a standard 2D release.
A Flat Image Can Show Depth
A 2D image has width and height, but filmmakers can make the photographed space feel deep. Perspective, overlapping objects, changes in scale, lighting and movement help viewers understand where subjects sit in relation to one another. A foreground doorway, an actor in the middle distance and a bright window at the back can create three clear layers.
Camera movement adds further depth cues. During a sideways move, nearby objects appear to cross the frame faster than distant objects. That relative movement remains visible in a 2D recording; stereoscopic glasses are not needed to understand it.

2D Versus Stereoscopic 3D
- 2D presentation: One picture is supplied to both eyes.
- Stereoscopic 3D: Separate viewpoints are delivered to the left and right eyes.
- 3D computer graphics: Objects are built in a three-dimensional scene, then rendered into images.
- 2D animation: Drawings or flat graphic elements are arranged and animated, sometimes with simulated depth.
Practical Production Example
An animated character may be modelled, lit and rendered in a 3D application, composited over live-action footage, and delivered as a normal 2D commercial. The production method uses three-dimensional tools, while the audience receives a single-view image. Naming the delivery format avoids confusing those two stages.
Common Mistakes
- Assuming 2D means visually flat or poorly lit.
- Calling every computer-animated film a stereoscopic release.
- Treating a 2D version of a stereoscopic project as a simple export without checking framing, titles and finishing.
- Using ‘2D’ as a substitute for the actual delivery resolution, frame rate or aspect ratio.

Frequently Asked Questions
Does a 2D film need a special camera?
No. Ordinary single-camera recording produces a single viewpoint. Camera choice still depends on the production’s image and workflow needs.
Can 2D animation include a moving camera?
Yes. Layered artwork, scaling and virtual camera moves can create the impression of movement through space.
