I try to install a video gallery but i cant.
Hey vicrub!
There are a couple of different ways to use videos with Enfold. You can use them with our sliders, color sections, and other shortcodes. If your trying to create a gallery of them though then perhaps creating some portfolio posts and using our portfolio shortcode would work best for you, http://kriesi.at/documentation/enfold/create-new-portfolio-item/.
As you create the portfolio posts you can set a featured image for each post and then set a link to a youtube or vimeo video in the “Overwrite portfolio link setting”. Now when you click on each item in your portfolio it will open up the video in a popup.
Regards,
Elliott
