e7car,
Here’s some text from the top of the settings page to help you do that task:
“Method 2 – If you want to do some formatting (e.g. add HTML to center a video) or have two or more videos next to each other on the same line, wrap each link with the [embedyt]…[/embedyt] shortcode. Tip for embedding videos on the same line: As shown in the example image below, decrease the size of each video so that they fit together on the same line (See the “How To Override Defaults” section for height and width instructions).”
You can find more in the instructions on the settings page.
