License question - after effect template

Hi, I’d like to purchase an After effect template (such as to create an intro for my Youtube videos. Basically I would create a short intro video with the template and I would insert this intro video in all of my Youtube videos. Your licensing model is a bit confusing: is one regular license enough for such a usage? I can’t imagine I would have to purchase a license for every single video but I’d rather be sure before I purchase the template. Thanks.
