Video Lightbox For Squarespace

Video Lightbox from BeyondSpace opens videos in an overlay on top of a Squarespace page instead of sending the visitor away or embedding a bulky player inline. It supports YouTube, Vimeo, Squarespace-hosted video (delivered as HLS) and custom video files uploaded through the link manager. It works by turning ordinary links, buttons and gallery clickthrough links into lightbox triggers using what BeyondSpace call video lightboxify URLs, so you do not need to touch a code block for each video once the plugin is installed.

What it does

Any link or gallery slide can become a video trigger, and Squarespace 7.1 gallery sections are supported out of the box, along with gallery blocks, auto layouts and product pages. Playback options such as autoplay and start time are controlled through parameters on the video URL. Zoomable images can sit alongside videos in the same lightbox gallery, so a portfolio can mix stills and film. On product pages it can replace static product images, or turn links and buttons in the additional info area into a video popup. The player reads the aspect ratio of your thumbnail and sizes itself to match, and videos can also play inline within a gallery rather than in the overlay, which is a tidy replacement for animated GIFs.

Who it suits

Videographers, wedding and event filmmakers, agencies with showreels, musicians and any business that wants a "watch the film" button on a page without the page becoming a wall of embedded players. It is also a neat way to make a gallery of thumbnails open videos rather than images, and shops that have product videos will get good use out of the product page options.

Considerations

This is a feature module of BeyondSpace's larger Lightbox Studio plugin rather than a separate codebase, so read the vendor page to understand what you are buying and whether the full Lightbox Studio would serve you better. The lightbox loads the video from YouTube, Vimeo or your host at click time, so slow or heavy videos still buffer; it does not make them lighter. Custom code needs a Squarespace Core plan or higher (Business or Commerce on older plans), and as with any injected code, a Squarespace update could require a plugin update from BeyondSpace.

Installation

The plugin is supplied as code you add to your site following BeyondSpace's instructions. You then point the links or gallery items you want to open in the lightbox at the video lightboxify URLs they describe. Setup is quick for a single button and takes a little longer if you are converting a whole gallery.
