Sometimes the recipes can do with video accompaniment, like demonstrating the pleating technique in carrot ginger pork baozi, but videos are so hard to glance through and one basically has to memorize everything from it before starting.

I have no idea why this trend of turning everything into a video seems so popular.
Facebook falsified statistics on how much people were watching videos, creating a huge movement to "pivot to video" which has infected absolutely everything. Slate has an explanation.

The shift from text to video was never about what normal people wanted, for Facebook or the media companies that followed its lead. It was always about what advertisers wanted: the captive attention of consumers.
