I know what you mean, like the water gets kinda pixelated. I think I.m recording in 1080 and I use imovie and burn the video to their highest setting. So I don't know where the issue is, but I'd like to figure it out because I see other people that have better video quality on there.I noticed a bit of video loss. I have had this problem as well. I think this is Youtube claiming to play 1080 but isn't encoding the high resolution video correctly. If you don't mind, what are your video settings?
