More information, at least in the information-theory sense, but much less knowledge. I.e. videos are much less efficient than text, or even static pictures. Take a second of the most insightful video you can find, and in the same space, you could easily cram an entire textbook on the same topic, complete with high-resolution images.
Just pulling a transcript of a given video, timing your reading, and comparing it to the length of the video would make this evident. And that's if the information delivery is perfectly optimized, which in most cases it's not. Compare 1hr of CNN to a 1hr college political science lecture, for example.
