Please keep in mind that YouTubes in video programming shouldnt be used as a substitute for proper watermarking, your videos can be downloaded free of watermarks when they have in video programming applied, it doesnt physically change the video itself and you should apply any watermarks you want permanently in the video in your video editing software using a PNG image and placing it on a track above the video clip. The in video programming has caused a lot of confusion when it comes to adding watermarks, so many people think their videos are watermarked when really they are not.
