Where is iMovie Trash?

I've read other posts that say there is no imovie Trash and that it's the regular trash or it's in the Finder. Not sure if that was referring to older versions of imovie. I deleted clips from imovie. My regular Mac trash is empty so they are not there. I dont see a trash in the Finder. And if I click MOVIES, I only see folders for Movie Projects and Movie Events. So where do deleted movies go? Is there a trash anywhere visible to the user? If not, does that mean that if you accidentally delete a movie, it is gone forever? Ive tried the imovie help menu but it doesnt say where the trash is ; it just guides me to File to put something in the trash. I must be missing something
