What about the picture you see before clicking on the actual video? This article of course is addressing the content of the videos, but I can't help but look at the comically cartoonish, overly dramatic -- clickbait -- picture preview of the video.
For example, there is a video about a tornado that passed close to a content author and the author posts video captured by their phone. In the preview image, you see the author "literally getting sucked into a tornado". Is that "altered and synthetic content"?
