By default, clicking a video thumbnail opens the video in a lightbox popup right on the listing page, keeping visitors on your site instead of navigating away. This article covers the lightbox and the related video player settings.

With the lightbox enabled, clicking a post thumbnail on the homepage, archives, or blog listings opens the video in a clean popup overlay — visitors watch it and continue browsing:
Control it in WPZOOM → Theme Options → General → Global Posts Options → Video Lightbox:
The lightbox works with YouTube, Vimeo, and self-hosted videos. Its script loads only when the option is enabled, so disabling it removes the extra weight entirely.
Self-hosted MP4 videos play in the theme’s built-in player. Pick its design in Theme Options → General → Video Settings → Video Player Style:
For external videos, the theme fetches thumbnails from the video platform’s API. Video API Thumbnail Size controls the resolution it requests:
| Size | YouTube | Vimeo |
|---|---|---|
| Small | 320×180 | 295×166 |
| Medium | 480×360 | 640×360 |
| Large | 640×480 | 960×540 |
| HighResolution (default) | 1920×1080 | 1280×720 |
Not every size exists for every video — the closest available one is used. Keep HighResolution unless you have a specific reason not to: modern layouts (and especially the Editorial style’s large 16:9 cards) need sharp thumbnails.
