Settings in Video Block
In the edit screen, you'll find the autoplay option. While autoplay can be useful in some cases, we do not recommend it. Not all browsers support autoplay, so even if this option is enabled, the video will not automatically start in all browsers.
Users often prefer to choose when to play the video themselves. If you want to use autoplay, we recommend setting it only if the video is in the header and immediately visible when the page loads.
General Settings
In the opened edit screen, you can adjust the general settings of the block through the four tabs (Content/Settings/Animation/Advanced). A description of the settings in the different tabs can be found on the edit page
