Shortcode- Tedtalk Video

You need to go to the tedtalk page and get the link and paste it in.

When I posted that it produced a link to a page on text explaining some technical difficulties. Since then it has started working.

Shortcodes – YouTube Video

Just paste in a youtube url and the player is embedded.

You can also paste in the embed code from YouTube and it will be converted to a shortcake, this is handy if you want to customise the video size or other options. For example avoid showing released videos.

Alternatively you can add ?rel=0 after the url before pasting it in: https://www.youtube.com/watch?v=u2wrYBPLsxg?rel=0

Which will hide related videos.
