Wordbooker doesn’t grab thumbnails of a video (vimeo in my case), but it does work for a lightbox gallery. So if u include them both in one post, u’ll eventually get a facebook post with a thumbnail. It doesn’t solve the issue, but it’s a walk around. Or u can set Wordbooker to grab a “Featured image”.. this way, u can chose the facebook post thumbnail manually.
Sorry if i didn’t explain it properly at first..
I don’t know if it’s any help, but what i did is just inserted a Lightbox gallery with stills into the post. It looks cool, professional and fakes it really good!
Heres an example:
