WP automatic can auto post youtube/vimeo videos on auto pilot and NewsMag is a popular wordpress theme that can display the video out of the box by providing a video link
here is how to integrate both
- add a custom field like in the screenshot
copy the value from this link http://pastebin.com/gS5RHPFZ
- set the custom format to video
- You can then remove the vid_player tag from the description as the theme will handle the display of the video
