Lost video & pix

Hello,

Would you happen to be using My Photo Stream? If so, that only keeps the photos from the last 30 days. Upgrading to iCloud Photos will retain all your photos and videos but also counts against your iCloud storage.

I hope this helps.

You would have to describe what you are doing, what happened, what you expected to happen, and the actual result. I cannot figure out what you're asking.
