Just one thing WIlbert about the test you did in the other thread on this problem :
Avs command "BlanckClip(color=$000000) gives a picture with Luma already clipped to 16. As does "BlanckClip(color=$ffffff) that gives L=235. And is not even said in the doc. |

i can't find better words. the old tv "delta tubes" have extreme bright limitations and show the very high light as "neon lights". then if one matiz is changed,all the colors change too cos the white is the result all basic colors in tv (59%green,30%red and11%blue = pure white. pure white means..... :roll: "not so pure" the "intention" of the limiter filter is special for this cases. the instable linearity from black to white change the matizes and the "background" grey of the luminance can't show the light grey or black cos the "cannons" don't do the perfect job. in the new tvs is different and we got more bright with less "miliamperes" and better balance betwwen the cannons. :arrow: sorry my poor english. ps: "instable linearity" ? 8O ahhh,you understand what i mean. :lol: :lol: |
I love to see professional explanations :-)

So, it's impossible to get L=0 in AviSynth using BlankClip, Levels, ColorYUV, etc. The only way is to import a clip with L=0 (made with TMPGEnc for example). |

Hi all..
Just my two cents on this.. Bchteam wrote: Quote:
three of them still up and running ie, 2 Apex AD-1500 and 1 AD-500, and the AD-500 diaplays my DVDs very lightly in color.. so I do see some of those blochy blocks floating around when scenes are solid etc. I don't think it's a TV issue, but it could be too.. I really think its a DVD player issue alltogether :!: -vhelp |

posted by SIF about "dark green", limiter, mpegedec3 and some more. ...see the explanations from Sh0dan (chrominance 128 is grey, 0 is green) posted in 1st September 2003 12:50 about dark green: http://forum.doom9.org/showthread.php?s=&threadid=60540 i still can see the dark green in some scenes! :!: |
more about levels and scales:
http://forum.doom9.org/showthread.php?s=&threadid=61537 and the last avisynth252 that i found: http://cultact-server.novi.dk/kpo/avisynth/avs_cvs.html ps: don't know why Sh0dan don't call for news versions?!? :? and why the "green dark" was forgoten?!?! ...still there! |
:roll:
more about "dark green": http://forum.doom9.org/showthread.php?s=&threadid=61927 thanks God,after months i'm not the only one who see it! |
For me if you check convert to yuv in tmpgenc, all dct blocks become invisible, but that's only dct.
I use deen and i gets rid of alot of background noise. what i need is a filter that can reduce blocks on flat areas. |
oh yes muhali3,
i'm using(testing) Deen("a3d",3,4,1,4), very cool for animes! but about the "dark green"... from the tmpgenc help file: "Output YUV data as basic YCbCr, not CCIR601 Enabling this cause the 8-bit value for the components to be of a value between 0 and 255 in YCbCr, and not the CCIR601 values of 16 to 235. This is usually disabled." :arrow: the problem of dark green is between 0(zero) to 16! for me, less than 16 means "more than black". then it can turn it worse,don't? :? |
