A new study published in Nature by University of Cambridge researchers just dropped a pixelated bomb on the entire Ultra-HD market, but as anyone with myopia can tell you, if you take your glasses off, even SD still looks pretty good :)

"File types" like avi, mp4, etc are container formats. Codecs encode video streams that can be held in different container formats. Some container formats can only hold video streams encoded with specific codecs.
