Description
In progressive content “Combing” is an interlacing artifact which may result from an incorrect frame rate conversion or from incorrect 3/2 pull-down removal that does not fully remove interlaced frames. In this case Combing is a very visible issue that is exacerbated by motion on screen. This creates a very poor customer experience, as the eye is drawn to the object edges on screen and the viewer is removed from the story.
Definition
Used in Checks, the system shall verify if the video contains material which shows combing. Optionally, the system may report the location(s) of the combing detected.

Used in Reports, the system shall report the location(s) of material showing combing.
