Most brands looking at stadium advertising for the first time come in with one general idea, "signage in a stadium", without knowing there are several genuinely different formats involved, each with a different cost, production process and audience. I produce content for the LED formats specifically, but it's worth understanding where that sits relative to everything else on offer.
Static perimeter signage
The simplest and oldest format: a printed board or vinyl banner fixed to the perimeter fence, showing one message for the life of the installation. It's a fixed cost for a fixed, permanent message, no production beyond the initial artwork and print. It suits a single sponsor wanting a permanent, always -on presence rather than a rotating campaign.
LED ribbon boards
A digital version of the same perimeter position, an extremely wide, thin strip of LED screen running the length of the sideline or try-line. Because it's a screen rather than print, several brands can rotate through the same physical space across a game, and the creative can change between fixtures without touching any hardware. This is the format I actually design and produce content for, built at the venue's exact technical spec rather than a generic video squeezed to fit.
Big screens and video boards
The large screens used for replays, sponsor stings and crowd content. A different format again, closer to a short television commercial than a ribbon board, with its own aspect ratio and a much shorter, punchier runtime since it's competing with live play for attention rather than sitting in the background of it.
Where the actual work is
For LED ribbon-board content specifically, the job isn't filming inside the stadium, it's designing and building the content itself: type oversized enough to read at that ratio, a logo that survives being cropped, and a loop timed to make sense against the run of play. I handle that build end to end, confirm the venue's exact technical spec before production starts, and deliver files ready to load directly into the venue's system.
