I have digitized about 60 hi-8 and mDVD's and now want to TAG them and import them into photos. Multiple family members would like to get the files. I'd like to insert the date, GPS info, and some key words, but don't want to have re-TAG them multiples times. I'd prefer to do it first then just import them into their Photos library from a thumb drive with everything correct already. Is there a way to do this with video files that apple Photos can use?
