So, let us hypothetically assume that you pressed delete YouTube video, and that your video deletes off of YouTube, but it was the wrong video. This is not the worst news, as we can re-upload the video, as long as you have the time and patience. Your first course of action here would be to re-upload the video. After that, it will have the same title, thumbnail, and length, but a different URL. YouTube allows you to change channel URLs, but not video URLs.
