Answer: some similarities between reading a speech and watching a video is that the person the is speaking in the speech or video is trying to get the readers attention in what he or she is stating. They will also both state there claims and show proof or evidence that goes towards what they are saying. Another way they are both alike is that they can both show emotion in what there stating. Wether they show emotion by body language (which would only be in a video) or by saying meaningful or emotional things (which can be in both).
Hope this helps you! Have a great day! :D
