I also found the following definitions (see quoted websites): (ENG) LUMA:The brightness signal in a video transmission.
(FR) LUMA KEY: Incrustation d'un premier plan (image A) sur un fond vidéo (image B). Le signal de découpe utilise les informations de luminance: on sélectionne une valeur de luminosité dans l'image B qui devienra transparente.
I found references to "Luma" and "Luma key" on several video-related French websites, always beginning with uppercase, often as technical specifications.
