I hope I’m not contradicting myself by agreeing with this - videos can be a great adjunct to stories. Some things just gotta move. Car crashes. Fires. Explosions. Dancing tiger cubs. Just make sure it is in addition to the text, and is optional to play, not autoplay.
But when the OP asked about video online news, most of the stories are talking head standing there basically reading a story. Nothing in what he or she says is that special that it has to be spoken. I can read the details faster than they can say them.
