So I just saw this. When I went to the video manager of my video, on the right of the edit button I saw "matched third party content". I clicked on it and I saw the following: And yes, I actually just ripped a game trailer from YouTube and uploaded it myself. Please note the video is in 'unlisted' mode since it was uploaded. I was just planning on making it public and I saw this. How should I proceed? Should I acknowledge it or dispute it or just ignore it and make my video public? Will the video be deleted when I make it public?
