You think that's bad? Imagine finding out that all video still encodes colour at half resolution simply because that is how analog tv worked.

- heckelson 10mo agoIsn't it the other way round? We did and still do chroma subsampling _because_ we don't see that much of a difference?
- seba_dos1 10mo agoI don't think that's correct. It's not "all video" - you can easily encode video without chroma subsampling - and it's not because this is how analog TV worked, but rather for the same reason why analog TV worked this way, which is the fact that it lets you encode significantly less data with barely noticeable quality loss. JPEGs do the same thing.
- shiandow 10mo agoIt's a very crude method, with modern codecs I would be very surprised if you didn't get a better image just encoding the chroma at a lower bitrate.
