Details
Description
"Pixel Error" is a visual corruption where one or several pixels in a frame will not display the correct captured information (it/they will differ from the pixels surrounding them). Also referred to as "Dead Pixel."

Pixel Error impacts the technical and content quality of the asset. Customer experience can be negatively impacted if Pixel Error on screen is bright against a dark background or hovers over a main character face.

This is never creative intent.

Any video assets created from this asset will contain Pixel Errors.
Definition
Used in Checks, the system shall review content for dead pixels. Optionally, the system may report timecodes at which dead pixels exist and their positions in the frame.

Used in Reports, the system reports timecodes at which dead pixels exist and their positions in the frame.
