It depends on the theme you are using. Generally to make a permanently imbedded video you would open the template file for your home page (sometimes called home.php) and paste it in there.
If your home page is widgetized then you can paste the code into a text widget and drag the widget to the proper location.
OR you can make your theme widgetized by following one of the many tutorials on how to widgetize a wordpress theme.
Hey, thanks do the help.
I am using the default theme.
Cheers.

@Harty do build a child theme for bp-default so your changes won’t be overwritten when BuddyPress is updated.
Cheers for the tip. Will do.
