FitVids integration

I’m trying to get things working with FitVids.js and was wondering if there is a simple callback that can be used. At the moment videos ‘above the fold’ are resizing perfectly, however anything else doesn’t seem to get wrapped in the .fluid-width-video-wrapper class and breaks the responsive layout.

Is there a simple workaround for this?

Thanks!
