To create a distinct UI – You must have very distinct elements.  It is very easy to use a logo from one of the many logo maker programs or import a semi-customized lower third into your videos.  The problem that you can have is that eventually, you will see your non-custom Design everywhere. 

 This is where designers end up having to change their entire brand strategies, because they downloaded their logo or other markings from Envato Elements. These designers took a quick and easy path, now their Marketing looks like their competitor’s marketing.
