This "story" (I'm using the term rather loosely here) tells of eight boxes you need to check on your way to producing a successful video for a brand, an event or an idea. The article is slightly self-serving, neither especially entertaining nor well written, and is mostly re-hashing commonly accepted media production standards in the digital era. In fact, you'd be hard-pressed to identify a single of those bullet points that is not applicable to any media production -- be it text, video, audio, images, or any other digital product.
