Transitions for 4k content

[#1]

Anyone know where I can pick up transitions for 4k video clips (aside from the stock ones that come with premiere pro)?  I am looking to up my game on more transition options, and have only really found transitions that work for 1080p content.  Thanks!

There are many plugins and extensions. I find this one to be very useful many times:
