What is bokeh in video?
Bokeh is the visual character of out-of-focus areas, especially the way points of light, edges, and highlights are rendered. It is not simply background blur; it describes whether that blur feels smooth, busy, soft, or distinctly shaped.
Wide apertures, close focus, and separated backgrounds make bokeh more visible, while lens design influences its character. Small lights in the background may become discs or other shapes determined partly by the aperture mechanism.
Bokeh can separate a subject and add atmosphere, but it should serve the scene. Strong blur can obscure location, make focus difficult, and leave an editor with fewer options to crop or combine takes.
Example in the edit
A singer stays sharp while string lights behind them turn into soft, rounded highlights.
Why editors use it
Its texture affects the mood of shallow-focus images and can make a background supportive rather than distracting.

Quick answers
Frequently asked questions about Bokeh
Is bokeh the same as shallow depth of field?
No. Shallow depth of field describes how much is sharp; bokeh describes the quality of the blur outside that sharp zone.
What produces round bokeh highlights?
Out-of-focus point lights often take on the shape of the lens aperture, which is commonly near-circular at wider settings.
Can bokeh be added in post-production?
It can be simulated, but natural bokeh also reflects lens behavior, scene depth, and highlights that are difficult to copy perfectly.
