No, video's do not hold information on how they were transferred, or who sent them.
If it was deleted a long time ago and the computer has been used since then the chances of retrieving it are extremely low anyway. If it wasn't deleted then all you need to do is a search for video files on your computer using the built in Windows search, but again that won't get you the person's email address. If you saved his entire email then that would have the email address, but not a video.
