hi I want to recover deleted videos from iPhone

Less than 30 days ago? Recover from "recently deleted" album.

Backup?

Exported to your hard drive?

Shared on social media?

Uploaded to other cloud drives (google photos, Amazon Photos, dropbox etc)?

If you've put them somewhere other than the place you've deleted them - you might be able to find them there. If you haven't, and it was more than 30 days ago, then they are gone.

From your backup of them.
