You’d be shocked how much planning goes on for each video. For a documentary-style piece, you have to do preliminary research, which can take several weeks sometimes, and mostly likely get the video approved by management.
Then you have preproduction where you make sure you have everything you need for the shoot based on the research you did earlier.
After that you have to line up schedules with both your crew and the subjects of your video, and get permits to shoot in the locations you’re planning to use (they’re real sticklers for that kind of thing in LA).
From there you have the actual shoot time, which can take anywhere from a few hours to a few months depending on a large variety of factors.
And finally, once you’ve gotten all your footage, you have to edit everything together, which for a larger company like Buzzfeed also includes things like graphics and captions for each video. This process can take weeks just by itself for a short video, and is typically one of the longest parts of any project.
And if there are actual scripts and hired actors involved, all of these steps can take even MORE time.
Bottom line, even without the red tape that you would have in a more traditional production setting, there is a ton of work that goes into making this kind of content.
