I need to recover an important 30 minute video lost on my iPhone 11s pro. Can you suggest an app or function?

Hi Keyplay,

Welcome to the Apple Community.

You may be fortunate to find the video in the "Recently Deleted" folder ?

Or, if it is longer than 30 days since you lost it, or permanently deleted it ...

• You may have a back-up you can use to restore the video.?
• Could there be a copy in iCloud, or on another devoice ?
• Anyone you have shared it with may have a copy ?

Recover or permanently delete deleted photos:

To recover deleted photos, or to permanently delete them, do the following:

1. Go to the Albums tab, then tap Recently Deleted under Utilities.
2. Tap Select, then choose the photos and videos you want to recover or delete.
3. Choose Recover or Delete at the bottom of the screen.

Sorry I don't know of any apps, if there are any, that could recover a permanently deleted video.

All the best :-)
