Free fx for davinchi

Hi! I want to start editing my gaming footages, so I need effects like motion blur, grain, shakes, custom masks, etc. As I found some of them are only in studio version. I dont want to buy studio version bcs a lot of paid features like 10bit, 32k, 120fps, etc will be useless for me. Is it possible to add external plugins with effects for free in free veesion?

Also would like to see any recommendations where I can find transitions, sounds, etc.
