The company built a set, specifically designed for vertical videos, that’s roughly 15 percent skinnier than a standard set and has cameras turned on their sides. Tastemade still has to fill up the other platforms, so it shoots the rest of its videos horizontally on high-resolution cameras, while keeping the action in the middle third of the screen so the footage can also run on Snapchat. TV monitors in the studio are marked with black tape that shows the Snapchat version’s frame. Afterward, segments are edited into multiple cuts: vertical for Snapchat, square for Instagram and Facebook, horizontal for YouTube and Apple TV.

Ёбаный пиздец.
