Hi,
Could you check following url
http://digon.imaginemthemes.com/wp/3-column-portfolio/
The forth item has a lightbox video link. You can activate this by entering video url to the portfolio item. The video embed will show up in the portfolio single page. It won’t display in lightbox. The video url field if filled will display in the lightbox.
Check page 31 of Help Guide. This field is marked as ‘Video Url’ – ‘Video url for lightbox’
Thanks
