Often the projects we work on require that our clients send us files. Usually these are logos, sometimes graphical branding elements, and sometimes existing footage, such as what's called running footage from a car manufacturer. There's a problem we have to address with almost every client: While most people know what jpgs and pngs are, these aren't the best way to send us images. And rarely does anyone know the difference between 4:2:0 and 4:2:2 footage (it's an important one). With that in mind, here are a few of the basics when it comes to file formats of both images and video. Pull on your suspenders and grab your pocket protectors—it's about to get real geeky up in here.
