I must commend YouTube for how far they have come technically. I joined reluctantly, because most videos were such poor quality I didn't relish being associated with that. NOW: this video was uploaded as an MPEG2 720P file - almost half-a-Gig. I was unhappy with it because my source had anomalies - cascades and flutters everywhere. Miraculously, after YouTube ran it through their filters and converter, turning it into an MP4 a fourth the file size of my upload, at 720P and full screen (24 inch monitor), it is perfectly clear - no anomalies that I have seen. My hat is off to you, YouTube! Good job! I said for years that one cannot make a video copy look better than the original, but I am happy I was wrong.
