Why defer videos?
When you have videos from Youtube, Wistia, Vimeo, etc. embedded in your webpages it causes your page to load slower.
Just about every video can be deferred until after your initial pageload which will allow your page to load quickly without having to gather all the files and resources that the video is requesting.
By deferring the video files you are often saving dozens of files requests and resource downloads and it can really make a difference for your page speed. Videos fall under the Render blocking javascript error you may see in pagespeed tools when you examine your site.
