I like using YouTube clips for my classes, but I don’t like the clutter: links to other videos when it’s done playing, the title showing at the top, low quality. So I play with the embed code:
See what I’ve added after the video code, ending with the ?
rel=0 > YouTube adds this when you deselect the “show related videos” on the embed code
vq=hd720 > means to show it in maximum resolution or HQ if it has it
showinfo=0 > to get rid of the title showing at the top of the clip
