This new feature is named Corrections.
I think you are already using this one; the most replayed part of the video.
But it might not get the viewers attention, but now YouTube has rolled out a solution.
YouTube already allows creators to edit some basic things of videos.
As with other info cards, this will also appear in the top right-hand corner of a video.
But, it will only appear when the first correction comes.
Viewers can see the correction notes in the videos description, as seen in the above screenshot.
you might also watch the below video fromYouTubesCreator Insiderchannel to understand it more precisely.
This feature is very useful for creators as well as for viewers.
