Example of Standard Teaser component with added inline video.
Video is added as "Video Asset" with uploaded files in MP4 and/or WEBM format (WEBM format is usually lighter, so it will be presented to the users if both are available)*.
* YouTube Video ID needs to be missing from Video Asset or otherwise it will take preference over the uploaded files.
It is always cropped to a square (if video is not of 1:1 proportions, it will position in the middle), autoplayed and played in loop.
Maximum displayed height is 560x560, so there's no point in having a file bigger than that.
