Problem:
I am using Clique (latest version). When adding a video into the portfolio section, Vimeo adds a letterbox to my 16:9 videos. It is not the light box’s doing since I notice that the letterbox is within the Vimeo player itself. However, there is not a letterbox on the original Vimeo video. My thought is that it must be a problem with the communication between the WordPress/Theme & Vimeo when pulling an embed code.
Solution:
Find the fancybox code in /js/functions.js.php, and try setting the width / height for the video and have the following code:
var fancybox = { init: function() { $j('.fancybox-media').fancybox({ margin: 50, width : 800, height : 450, aspectRatio : true, helpers : { media : {} } }); } };
Then it should keep the aspect ratio to the width/height you provide.
