What are the best videos that teach how to make macros???

This is something I never bothered with but I'd love to learn now

Video?
You just write text into a field, I don't think a video would be the best to show you that.
http://ffxiv.consolegameswiki.com/wiki/Macro - here you can see all the commands for macros.

Then you just write something like this:
/macroicon "Ressurection"
/action "Swiftcast"
/wait 0.5
/action "Ressurection"
