I'm planing to upgrade my tv and htpc to 4k OLED and a GTX 980. I've got some questions:
- Who is running a 4K TV with GTX 980 and madvt? What settings regarding imagedoubling/chroma upscaling are possible with this card when upscaling 1080p mkv files to 4k? - Is it possible to set up a custom resolution to run it in 23,976 mode to avoid repeated/skipped frames in a 3 hours movie? I'm asking cause I'm coming from an ATI card wich could do 23,976 Hz good enough to avid skipped/repeated frames vor 6-7 hours |

on my 55" VT60 panasonic plasma I use:
LIMITED (RGB 16-235 @ GPU driver), FULL (RGB 0-255 @ MadVR), LIMITED (16-235 at TV) (nice colors all around but two quantization steps first on video driver -range conversion-, then in madvr) For the many reasons that has been mentioned by James: 1. my HD cable box outputs in Limited and is not changeable 2. my blu-ray player outputs in Limited which is especially important when watching streaming content through Netflix and Amazon 3. my receiver/soundbar which has all 3 devices routed through it (HTPC, blu-ray player, HD cable box) and having all 3 using different settings is impossible 4. when watching content through the TV itself be it through the HD antenna for OTA broadcasts or internal apps, they all use Limited. 5. when watching content through the HTPC on the TV such as gaming or watching youtube or any other streaming sites, I also want to keep all video levels the same

My Panasonic ST60 Plasma behaves best (no banding) only in Limited range when 4:4:4 is enabled. I would recommend sending Limited Range to your TV. GPU Limited, madVR Full, TV limited (Good all around but two [invisible] conversion stages). Or GPU Full, madVR Limited, TV Limited (No stage conversions, best for Video but clipped PC range). The question is whether your TV does 4:4:4 only in PC mode or in TV mode also (if at all)? I would aim my priority for Smooth (no banding) 4:4:4 first, then on less range conversions. Quote:
I'm not advocating for limited range when using TV, but in my experience limited range gives more accurate picture with my TV and without unnecessary conversion stages if GPU+madVR set accordingly. The Panasonic ST/VT 50/60 only like limited range with 4:4:4 like you already noticed. If a TV behaves well in full range like a PC monitor, then by all means, use GPU Full, madVR Full, TV Full.

The skipping frames are not something to bother for unless you have a very senzitive eye sight. For instance I use reclock with good results , of course with the 32 bit limitation. There is no reclock for x64(yet) Last edited by edigee; 25th June 2015 at 19:52. |

So are you saying that Limited range is better for each TV out there? I totally agree that all BD's use Limited range, but I figured that if your TV supports 12bit + Full range + RGB then gradients would be even smoother due to having more than 0-255 levels. On my Samsung SPVA and 12bit setting + Full range + RGB has much better gradient smoothness than 8bit/12bit + Limited range OUTSIDE of madVR (on desktop that is).

I now understand that my Samsung 40inch LedTV can do both FULL and LIMITED by way of toggling "HDMI Black Level" to NORMAL (0-255) and LOW (16-235) and also my panel can do FULL and LIMITED range RGB 4:4:4 so now the question is what are the advantages of using FULL, FULL, FULL config compared to FULL, LIMITED, LIMITED config? it seems my panel is a very flexible one and can do either both config, so i'm confused what config to use. P.S. just want to put a nail on this topic and move on. |

What James says about his plasma doesn't apply to your LCD. Many LCD telly's are perfectly capable of replicating a PC monitor and will do full RGB 4:4:4 fine. I calibrated my Sony telly running AVS patterns in madVR outputting full RGB 4:4:4 using an EyeOne Pro with Colour HCFR and the results were nigh on reference. |

Ok thanks, then my next mission is too calibrate this panel but it seems i'll be needing some high-end expensive equipment just for that. hm.. I think I'll just have to settle with default settings of my Samsung Telly (Default Movie Profile)

To test your TV for 4:4:4 and Banding,
Banding Test: Smooth Grey Gradient Banding Test 2Smooth Color Gradient 4:4:4 Test: Chroma 4:4:4 Image You should see 4:4:4 and no banding at all. If your TV/Projector/Monitor can display 4:4:4 Full range without banding, it would be ideal because madVR's dithering is top quality.

FineSharp is really too bad, madvr needs implementation of LimitedSharpenFasterMC and UnsharpHQ from the avisynth world.
Avisynth script chain: Code:
SetMTMode(3,0) ffdshow_source() SetMTmode(2,0) LimitedSharpenFasterMC(1) UnsharpHQ(THRESHOLD=80,SHARPSTR=0.1,SMOOTH=0.2) GradFun2db() SetMTMode(1) GetMTMode(false) > 0 ? distributor() : last Code:
function LimitedSharpenFasterMC(clip clp,int "strength") { ox=clp.width oy=clp.height ss_x=1.5 ss_y=1.5 wide=true softdec=-1 soft=softdec!=-1 ? softdec : sqrt((((ss_x+ss_y)/2.0-1.0)*100.0))*10 soft=soft>100 ? 100 : soft ssx=round(float(ox*ss_x/8)*8) ssy=round(float(oy*ss_y/8)*8) clp.isYV12() ? clp : clp.converttoyv12() ss_x !=1.0 || ss_y !=1.0 ? last.spline144resize(ssx,ssy):last tmp=last dark_limit1=tmp.mt_inpand() bright_limit1=tmp.mt_expand() dark_limit=(wide==false) ? dark_limit1 : dark_limit1.removegrain(20,-1).mt_inpand() bright_limit=(wide==false) ? bright_limit1 : bright_limit1.removegrain(20,-1).mt_expand() minmaxavg=mt_average(dark_limit1,bright_limit1) Str=string(float(strength)/100.0) normsharp=mt_lutxy(tmp,tmp.removegrain(11,-1),"x y == x x x y - abs 16 / 1 2 / ^ 16 * "+Str+ \ " * x y - 2 ^ x y - 2 ^ "+Str+" 100 * 25 / + / * x y - x y - abs / * + ?") last=mt_clamp(normsharp,bright_limit,dark_limit,1,1) clp.isYV12() ? tmp.mergeluma(last) : tmp.mergeluma(last.converttoyuy2()) return last } |
