I continue to be frustrated by this dilemma. I tried all the suggestions made with no real success. I tried resurrecting iPhoto and was told it is not compatible with El Capitan. As I reported earlier I came up with the work around taking individual photos to the desktop as movies and importing them that way. It worked for the project I was working at that time but that was only 13 photos. This project has 200 photos so it is really impractical to use that approach. I then used that method for the entire photo file but it imported the file as a continuous "movie" making it impossible to edit them in the movie and cannot insert transitions between clips. This was so intuitive and easy before these "improvements". Can't believe the technology has moved backward
