How to use video block

If you have a video that is more than 5MB large you need to upload it to YouTube and paste the link here, and you can create a preload video, no more than 5MB in size, that you can put in the media field. If you add a YouTube video, on the preload video will be shown a play button that will open a popup with a YouTube video.
