Are you looping video content in front of your customers? You should be. But what's the best TV to buy? The cheapest? Not always. There are plenty of tech blogs devoted to the latest and greatest TVs, but how many of them are devoted to what TVs to buy for the corporate office? At home, you want the best bang for your buck, emphasis on the bang. But at work, the emphasis is probably more on the buck, and 4k? Maybe a better idea to stay away from it!
Some people have this misconception that film production somehow means "have camera, will shoot." A production company is not a videographer, a one-man band, or a lone person self-styling themselves as a filmmaker. Film production, like most businesses, has a lot of facets. There's the obvious stuff, of course: knowing lighting, composition, and that just so angle for a shotgun mic that makes will record audio. It's knowing the difference between 4:2:2 and 4:2:0, and how to craft a compelling story. But it's also a business. And, to make everything smoothly, there's IT.
