To me it's that the information density of video or audio content can vary wildly, much like writing. But while with writing your speed of processing it can adjust more or less automatically with how much you need to think about it what you're reading, with video and audio you need to take positive steps to do the same thing. And in general most people most people can listen faster than most people can speak, much like most people can read faster than most people can write. But then I can understand the impetus to just plow through information like quantity is all that matters, so if you're overdoing that it makes sense to try to pump the brakes.
