Dr.Erness who I had for Religion and Russian history in college smart now retired professor in northern Iowa attention span of a human usually is 5 to 10 minutes.
The good Doctor if history filled his classes with tons of information in 5 to 10 minute segments.
Im trying to keep my segments of videoing to 5 to 10 minutes also niw. Youtube wants us to have 30 or more minutes. People will view the end of something if a Chapter is 36 minites and your camera on your smart phone will max. Record 32 minutes with over hang.
See its the over bits that people will hear. Totally missing like Professor Needham use to call it the meat and potatoes.
That’s silly you might think.Trust me I have recorded long and shorts. Short clips are more time condumming. But Youtube is about viewers.
