Tips for educational videos

I know it has been promised as such, but I am not sure about the video format as written (drawn even) documentation is more versatile and better suitable (in most cases).

For instance it allows for users to skim through the sections that are already known, whereas video (kind of) has chronological - erm - “requirements” for watching (admittedly one can "fast-forward / skip through video too, but it is complexer to find a specific subject etc. At least when using regular video with little to no meta-data).

Also written documentation is better sustainable (easier to correct / keep up to date etc.).
