If you have an iPhone 4, there are a few ways to retrieve deleted videos from the device. The first is to use the “Delete Videos” option in the Photos app. Once you select this option, a screen will appear that asks you to confirm deletion. If you choose to delete the videos, they will be deleted from your device and won’t be recoverable. The second way is to use the “Restore Videos” option in iTunes. This will restore all of your deleted videos to your device. The third way is to use iCloud Drive. This service allows you to store all of your videos on iCloud Drive and then access them from any computer or device that has an iCloud account. Once you select “Restore Videos” in iTunes, it will start restoring your videos one by one.
