As with the image gallery, when you first create a video gallery, you are given a set of options. The first is whether to place the video gallery in the main content or sub content section. Next is whether to show the image title for the thumbnail.
These options will be available as settings after the gallery is created.
The next section is where you add the video. First decide if you want to use a video host or a local file. Enter the video title. If you chose a video host (YouTube, Vimeo or Daily Motion), you'll need the video id. Upload an image for the gallery thumbnail. If you're storing the video locally, you'll need to upload a mp4 and a webm version of the video. This is to ensure playability over all devices. We recommend using a video host.
