Hi,
I am having to produce a couple of videos for a client that is sponsoring my city's football team. The 30 sec spots will play on the screens at the stadium. The stadium's tech people have let us know that each spot must have a 'key number'.
Can anyone explain exactly what they mean? And what is a 'key number' in the modern sense...I know for film they are this:
<p style="padding-left: 30px;">Numbers on the side of film stock created during film manufacture that
are visible on the developed negative and positive prints made
therefrom
But can someone explain what they are requesting when asking for a key number?
Thanks,
