Slideshare, Vimeo, Wistia, Youtube APIs

The various video related APIs allow NGFB to retrieve information about embedded videos in your content — like the original video dimensions (different than the embedded object/iframe dimensions), the preferred video URL, and the preview image. The video URL will also be different for the Facebook / Open Graph meta tags, which need URLs to flash video files, and Twitter Card meta tags that require URLs to embeddable content.

Here’s an example showing the difference in meta tags between the Free version, which does not support video APIs or Twitter Cards, and the Pro version which does.

When the example post is shared on Twitter, the tweet can be expanded to include the embedded video.
