Anamorphic video is a shooting technique that allows for achieving a widescreen cinematic image. It uses a special anamorphic lens that horizontally compresses the image, effectively squeezing it into a narrower format that the sensor can record. The resulting footage therefore looks unnaturally stretched vertically. In post-production, during subsequent computer adjustments, the image is digitally stretched back to the correct widescreen aspect ratio. This process creates specific visual characteristics, such as oval blurred points of light in the background, known as “bokeh,” and characteristic horizontal lens flares.
