The YouTube official blog announced new “edit” feature that allows users to edit uploaded videos right on YouTube and maintain the same video IDs.
This means a user keep his/her view count and comments, and all existing links to the video will continue to work. With edit feature it is possible to stabilize hand-held footage, rotate a video, and boost the contrast and colors and try effects.
It is also possible to revert to the original version of video and save edits into a new video. But the popular videos with over 1,000 views and videos with third-party content can only be saved as new videos once edited.
