I organize all of my photos and videos on the Photos app in Mac, (with everything in the folder Photos Library.photoslibrary). I also disabled all iCloud Photo Library , My Photo Stream and iCloud Photo Sharing.
Then I sync photos and videos through iTunes with the options "copy photos from Photos" . iTunes can correctly count the number of items in my Mac's Photos app (number of photos + number of videos). However, when it tries to sync the videos, itunes displays "syncing 140 videos" and then just skip over all of them. All the photos are synced correctly though.
Does anyone know how to solve this? Thanks!
