Note that if you delete a YouTube video, the action is permanent and you cannot ever restore the video via YouTube or recover any interaction (likes or comments). Also note that you can only remove videos that you have personally uploaded.
Now, as we had already warned you, if you still want to delete your video, follow these steps.
Note that these instructions are for the YouTube website. It is currently not possible to delete a video via YouTube mobile site. You can also delete videos via the Android and iOS application. However the process is different for both mobile applications.
Immediately after deleting a video, no YouTube viewers will be able to see it, although it may still show up in search results for a brief period of time.
