Play videos without Lightbox?

I was able to create responsive video galleries in a vertical format with some very specific settings (Masonry, crop images).

HOWEVER, the videos will only play if I use Lightbox – open in Lightbox Gallery. I want the videos to play when they are static on the page (on click). How do make my video galleries without Lightbox?
