Doing advanced transitions in video editing

Hey, I‘ve heard that it‘s possible to do advanced transitions from one video to another with blender. I only know how to do basic stuff like fade ins and outs.
Does anyone know how to do these or where I can find more information about that?

Do you have examples of what you are looking for?

Something like in the video above.
I don‘t have specific transitions in mind tbh, I just want to add some more special ones that look more impressive than the basic ones like fading.
