There are a lot of plugins that allow users to embed videos using a shortcode. 
Now there’s one more out there.
Video Embeds currently supports YouTube and Vimeo.
Video Embeds allows for control over many of YouTube’s embed paramaters and 
all of Vimeo’s embed parameters. Set default values for all available options 
on the settings page.
