I hate the type of ‘instructional videos’ that have (likely programmatically) edited all and any short pause in the audio making the video appear as a 30+min continuous speak.
I mostly interpret this as ‘see me see me - I’m good!’ in stead of ‘let me try to educate you about this subject’.
All the natural pauses between sentences gives a much better and natural flow.
This also includes ‘oups I made a mistake .. and fixed it like this…’
Just like the line breaks in this comment serves a purpose;-)
One great example of a really good tutorial is Eivind Fonn’s Spacemacs ABC videos: https://youtu.be/2y9NLIbNf_I
Here’s my worst example of how not to teach: https://youtu.be/qtIqKaDlqXo
This series is also bad as there is way too much zoom in and out (which distract all but the presenter!)
