The document discusses how the combination of the main music video product and ancillary texts (poster and digipack) were effectively linked through consistent design elements. Specifically, it notes that a black and white color scheme, similar fonts, inclusion of the same video scene, and lighting that hits only half the artist's face in both the poster and digipack help to tie the pieces together and promote a unified marketing message. Maintaining these design consistencies across the different media makes the overall campaign look more professional and helps viewers easily identify the authentic pieces.
