Importing a dvd that I made into photos
I am using a MacBook Pro with High Sierra 10.13.3
I converted our 8mm home movies and VHS tapes into DVDs several years ago. Now I have iCloud storage in Photos and I also have a Dropbox account. I would like to load these DVDs into these storage files to be able to view them on my iPad or my iPhone as well as share them with my family using my Dropbox account. I have been able to do this with some recent videos that I have taken with my iPhone without any problem. However, I am not having any luck with loading the older DVDs into the Photos app or iMovie from my MacBook Pro desktop. I believe that the newer videos that I have taken with my iPhone and also loaded into my iMovie app creates an MP4 file which seems to be able to be viewed from my iPad and/or my iPhone.
Is there a simple way to load my old DVDs into these storage mediums which will allow them to be conveniently viewed for my iPad and/or iPhone?
