Every single training video I've encountered in almost 30 years of work falls into 2 categories: spend an hour on very basic things that are repeated over and over, then insert a couple of very technical, very useless deep dive topics. At the end, you open up the product guide and read it.
The other category is usually a guy recording himself and his screen, doing very technical very useful stuff, and you watch him type commands and do something. This is completely useless - you can't copy/paste into your notes, the commands he types is forgotten in 5 minutes, and at the end, you open the admin guide and read it.
There are some things to be trained on for which the video format was not designed. Things like coding, things like running different commands to deploy something. Why is video training so popular? No one I know learns jack from videos.
