Once a user has deleted a video from YouTube, then it can not be recovered. The only option is to re-upload it. The previous view count and comments will be lost. YouTube do not see themselves as a video storage or back-up service, so do not allow deleted videos to be recovered.
Searching for a solution to do this does give the indication that it is possible to recover a video, but this information is either out-of-date or simply wrong. Contacting YouTube’s creator support does not get a video restored.
YouTube do warn that deleting the video will be permanent:
Your only option is to keep back-ups of videos and if you want to restore a video that you deleted, then you need to start afresh with a new upload of the video.
For most its not.
A study done by the Offenburg University Of Applied Sciences reported that 96.5% of YouTubers won’t earn enough from their videos to cross what is the poverty line in the USA. The study also pointed out that that once a YouTuber hits it big and enters the top 3% of creators who receive 90% of the site’s views, they still may only make an estimated $16,800 a year.
