Study Boldly Claims 4K And 8K TVs Aren't Much Better Than HD To Your Eyes, But Is It True?

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 :)

An overly compressed 4k stream will look far worse than a good quality 1080p. We keep upping the resolution without getting newer codecs and not adjusting the bitrate.

I went looking for a quick explainer on this and that side of youtube goes so indepth I am more confused.

On codecs and bitrate? It’s basically codec = file type (.avi, .mp4) and bitrate is how much data is sent per second for the video. Videos only track what changed between frames, so a video of a still image can be 4k with a really low bitrate, but if things are moving it’ll get really blurry with a low bitrate even in 4k.

“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.

ah yeah I figured it wasn’t quite right, I just remember seeing the codec on the details and figured it was tied to it, thanks.
