Incorrect dimensions, stand alone video as shown below. This is the issue I’m having problems with.
Notice that the height dimension of the following video is very large compared to the videos displayed below. It’s not displaying at the standard 16:9, although the video is sized for a standard 16:9 within YOUTUBE.
The following video is displays correctly, but has to be held within a playlist to get the desired results:
Correctly sized, held within a playlist, without any other videos. This video does display at the correct 16:9 dimension and fits entirely within the display.
Another example of a correctly displaying video, just to show you how they usually look. All video on my site display correctly except the top video on this page.
