People in general are prone to watch a video rather than reading a body of text; but writing (<em>reading for the audience</em>) has also certain advantages, such as enhancing connectivity in the brain more accurately.
Albeit <em>video</em> allows to deliver a massive amount of information in so many ways with several communication styles, <em>writing</em> also allows what is called <em>"asynchronous communication"</em>, which means it doesn't require the communicator to be present in the same place and/or time as the receptor.
<em>Writing</em>, <em>Video</em>, printing and cinema, they all share the advantage of asynchronous communication.
But to be fair and straightforward, they both share a simple advantage:
<em>"They both give information"</em>
