Replace videos

Unfortunately, you won't be able to replace an old video with a new one and keep the original view count, comments or ratings. Instead, you may want to try using annotations or link to the new version of the video from your old video.

You can also make changes to a video you've already uploaded by using YouTube Video Enhancements. (In order to be eligible for YouTube Video Enhancements, your video must not have received more than 1,000 views and not have a Content ID Match.)
