View Full Version : What causes edge enhancement? stuartbrown21 03-01-08, 08:49 AM Just wondering really............I understand that colour banding and macroblocking for instance are a direct result of the encoding process, and that an increase in bitrate would cure these, but what causes edge enhancement? Is it also a result of low bitrates, or is it created deliberately by the person authoring the encode?

It's when the studios doing the encode think it doesn't look sharp enough so they add in artificial edge enhancement sometimes PS: I don't think increasing the bitrate would always cure colour banding (it might also be a limitation of the HDTV or the 12 bit to 8 bit conversion or the 8 bit source) Timothy Ramzyk 03-01-08, 09:04 AM It's deliberate, it's the artificial boosting of contrast along already contrasting edges. bplewis24 03-01-08, 09:34 AM What causes edge enhancement?

Brandon I don't agree with some of your posts but that one is spot on! :D inspector 03-01-08, 09:46 AM they do it while watching their 27" screens!

Here is a good read about EE (http://www.videophile.info/Guide_EE/Page_01.htm). jvillain 03-02-08, 11:07 AM Great link. Thanks for posting it. |
