Due to Facebook restrictions, Spotlightr videos are shareable but not viewable on the Facebook timeline.
This means that you can post a Splash Screen or Share image which the viewer can then click-thru to a page that has the video. So a viewer clicks on your Spotlightr post (image) he is automatically redirected to the link that you specify, which is by default a Watch Page.
On the Watch Page you will be able to count your views and read the comments that others leave below and by using the Social Sharing settings, you can change the actual link your viewers will be redirected to, the actual splash screen, thumbnail and share tags.
For more details on the sharing settings please check this article.
