On platforms like udemy, the good courses range from 1.5 hours to as much as 97 hours. For this length, the shorter the better for individual videos.

For YouTube playlists, the same. However, for one-off youtube tutorial videos, I do long videos as well.

Not for me. I've taken and completed well over 50 courses by now (took health-related time off work for a few years but when I felt better wanted to do something), and the most frustrating courses where Udacity courses (and a few of the edX courses) where it felt like I had to click Next Next Next Next continuously, could not take my hand off the keyboard and lean back in my chair because there was the next silly easy question to answer and "Next" to click for the next short soundbite video. I definitely prefer well-made(!) longer videos.

The worst is when they start each and every 3.5 minute video with a ten second introduction, for those who already forgot what course they are in and what they just heard last only three minutes ago.

When I see things like this, or the doctor that I saw yesterday (who didn't know me) immediately switching to a "baby talk" style (for all conversations with her patients, I later observed) I wonder what kind of people (students, patients) they have to deal with in their jobs that they switch to by default assuming the worst.
