THere are about a million different ways to identify duplicate photos on either Mac or iOS, but I have yet to find any way to identify duplicate VIDEOS! I have accidently imported into Photos thousands of videos from multiple locations, so now I have a real mess having three or four different imports of the same video. The video files were different filenames, so the import succeeded. ANyone know of a reliable way to identify and remove duplicate identical videos on mac Photos app?? help!
