Just a note for myself, but may help others.
Today I made a short video demonstrating how to submit application for Fellowship of Higher Education Academy (no use outside the University of Brighton).
To embed a youtube on a website is simply a matter of clicking 'share' then 'embed' then copying the code into the html part of the website.
Until last year Youtube contained an option to 'embed old code'. Until today I didn't really know why this was necessary, but some websites and software still require the old code. The Brighton CLT website is built in Concrete 5 (or at least the version we have), which does not support the new youtube embed code.
Fortunately, help is at hand from http://www.gorissen.info/Pierre/files/YouTube_code.htm Just paste the youtube link, click 'generate' and the site generates the old code.
