Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

Unfortunately currently that was not possible to display 4 columns into the video module at this point of time.

Has there been a solution to create a horizontal video display, for Recent Videos Module?

I think you can try this following CSS to achieve this.

body #es.mod-es-videos .mod-card {

    display: inline-block;

    width: 23%;

}
