No auto post when posting video embed

The plugin doesn’t seem to update twitter if a video is used as a post, I am unsure if this is twitter only or affects other sites.

The structure of my posts are;

Title
embed code
tags

I am not using any text or descriptions in the post body so can only assume this is why the post isn’t sent to twitter.
