What are some recommended resources for finding cool transition tutorials?

I love that Hitfilm Express comes with pretty cool transitions as standard, and that we have the freedom to customise some of them to our heart's content. But, I've looked at a lot of YouTube videos and scoured the web for any transitions that we can create (and maybe save as a preset) or some that we can import into our projects from elsewhere.

In particular, I've been trying to get the spin transition for quite some time. However, I've been unsuccessful. Seeing a video like this (https://www.youtube.com/watch?v=RnCxzziomYk) seems easy enough, but I never quite get the hang of some transitions. Are there any videos/downloadable resources/packs I can get my hands on to achieve these transitions? Or, should I just stick with what I've got? I'd love to hear some thoughts!
