how to recover a delted video
Video I took got accidentally deleted how do I recover it
Deleted from where ? Photos app on and iOS device (if it is then not sure why you're asking in the iTunes Store forum) ? Computer ?
Guessing that you are referring to the Photos then is it still in the Deleted album in the app (assuming that the device is on a high enough iOS version to have the Deleted album) ? If not do you have a backup of the device which was taken when the video was on it, if you do you could restore to that (after copying off anything done since the backup)
