Well, a couple of things:

Heimr has the right idea. Videos are used sparingly because we use images sparingly. We focus on text to provide information, while things like images are there solely for supplementation. Videos, on the other hand, are like .gifs in the sense that there is movement, thus they are distracting from textual information.

While things like the Frozen Fever trailer are good for giving us a sneak peek at what's coming, they don't provide any information for the article itself that cannot be expressed in words. For that reason, they are pretty much removed on sight.
