You seem to be implying that this is not possible to do in a video (which I don't agree with), and that this is unfixable in a wiki (which I also don't agree with).

That's why articles link to the the root access article when they mention root access. None of the problems you have with the wiki are insurmountable, and I can't say I love the idea of people running off to create duplicate tutorials elsewhere on the site.

Why not instead of doing your own little thing over there come out and help with the wiki over here. There's no need for the videos to be separate. Why not, instead, take wiki articles and create videos to go with them? Then we can embed a link to the video on YouTube on wherever at the top of every page that has one.

Then you've got a text method for people that prefer it and a video method for people who prefer that, and if the videographer is following along with they text, they may be able to spot those missing or assumed steps and improve the text article while they're creating a video.

Or if somebody creates a video, then they simply slap it on a new page and either add text steps themselves or wait for somebody else to do it.

This combines the documentation efforts and keeps them in a single location. A win-win for everybody.
