Recommend us video tutorials and effects

To all videographers and cine artists. I thought i can create separate thread for the video only stuff! (Leona95 already created similar thread thanks for that but most of people commented about Photography related courses)
So tell us what video tutorials on this site you found very useful (learned a lot). And video effects (luts, overlays etc) that you like and use often on your projects.
My favourites are
Phillip bloom courses, fulltimefilmmaker courses
Effects: lens distortions (almost all of them) tell me yours
