Online videos require equipment such as web cameras and recording. I use my computer while in my underwear, so I don't always want a camera recording me. Online videos can be very bad for privacy if someone is videotaping me without me noticing the photographer. How do you guard your privacy? There are surveillance cameras in most cities and most rooms. We are one nation under surveillance. How do I keep any of that surveillance from appearing on YouTube for the world to see?
The good thing about videos is their instructional value. You can hear it while reading what in on the cameras. A good instructional video will be remembered. It is also good for the distribution of instruction, since people who don't have money can watch the videos. I used videos to look up old songs I have not heard in years, such as "The Mary Ellen Carter." I look for polka music and found Loituma's song performed live, "Ieva's Polka." I listened to Enya and the visual aids made the songs better.
I will want to be recorded when I am instructing and want my visual aids to be viewed again and again, without me shouting "I JUST TOLD YOU THAT" to people who can;t stand spending three hours listening to someone talking or reading a long boring technical manual. Rote memorization is obsolete thanks to online hosted videos.
