As desired, you can use the VideoAttribute
parameter to specify border
and corner settings for your video tiles. You can specify colors, widths, and rounded
corners. You can also specify a highlight color, and the border changes to that color
when someone speaks.
Your attribute settings apply to all layouts, regardless of content sharing.
The following image shows a video tile with a border color and corner radius applied.

The following example shows how to use each attribute. In this case, video tiles have
rounded corners with a five-pixel radius. The tiles have a green border, also five
pixels wide. When the speaker talks, the HighlightColor
attribute changes
the border color to red.
