Is it right that MadVR does by it's dithering, in general, same correction of color space as videofilter does by YUV -> RGB conversion and movies will be look correctly on simple PC monitor if leave that option on "untouched"? Or, maybe, should I do something else to watch videos correctly in this option mode? Last edited by mysterix; 6th April 2016 at 08:34. Reason: Info correction |

Someone could tell me about the option present a frame every v sync? I made some tests but i really don t knoe if help or not... this option low a little me tv refresh rate, sometimes seens to smooth sometimes seens to crap... when should i use this? Why d3d9 don t have the same? If i try reclock should i use that or not?

Ideally it would be better if madVR worked perfectly with it disabled but the only downside is a small performance hit. It is a good option if it prevents presentation glitches but if you don't have presentation glitches I wouldn't worry about it at all. Reclock is not relevant.

and with reclock alters the the clock adaptations compared to d3d9 and d3d11 without this... do you know how d3d9 handle the frames and v sync?

I am pretty sure D3D9 always presents a new frame for every v-sync.

I usually disable that option but I don't think this is expected to be broken.

Hi, I just wanted to leave feedback on a system that isn't high-end but still fairly decent. I'm using an Intel Broadwell HD Graphics 6000 GPU with an older version of MadVR .89.18 using the D3D 9 path, LAV 0.68 on an Intel NUC5i5RYK running Windows 7.
Since I cannot use the high-end scaling algorithms, I focused on the ones that I could. I'm sensitive to things like PWM, dithering and see momentary distortion--if I am watching something in motion then look away at a still object. So I am picky to say the least. There was too much talk in the past about people liking Jinc AR/Jinc AR for both image and chroma upscaling and I think they are wrong for just selecting it as automatically the best. There's something about Jinc that I find has this sort of blurry oily look to it. It's subtle, but it is there and I can't help noticing it. After I tested awhile with chroma upscaling on video, most easily done with video that you are not image upscaling or downscaling, I think Mitchell-Netravali with the anti-ringing filter checked is a good one to use for chroma upscaling. It seems to have that right mix of clarity with just a hint of smoothing which I think also comes in handy with lower resolution sources or bitrates. People's faces are a good thing to focus on, not as a still, but while in motion. Skin pores too visible? Then the algo is too sharp. Skin pores or other stuff too smeared pushing them slightly into the uncanny valley direction? Then the algo is too smooth. Same thing with backgrounds.. dancing pixels vs smears. Certainly it has been eclipsed by the new high-end stuff, but if you're not on a high end system like mine I urge you to consider Mitchell-Netravali for chroma upscaling media, including anime, not solely video. For image upscaling, I tend to be lazy and just use DXVA for both chroma and image. If you don't want to do that, then Lanczos 3 Anti-Ringing is a fine choice. You don't want it too sharp or too smooth. Lanczos 4 is going to be smoother than 3, which you don't need if you're already using Mitchell-Netravali for chroma which is already leaning on the smooth side. Adding both will be too smooth I find. 3 is a better choice than 4. I never used Spline much at all. I found it was too similar to Lanczos but different in a Coke vs Pepsi sense. Everyone's setup is different. A link I will throw in here that I just stumbled across, http://faculty.cs.tamu.edu/schaefer/...ine/index.html there is a paper too if you shorten the URL. The link shows the effect of filters on SVG rasterization. Maybe it has been seen here before, but new to me and interesting to play with, the patterns are designed to expose aliasing problems. |

I have a 60" ST60 and I'm still trying to figure out the best balance of options for it (I watch about a 50/50 split of 720p regular TV and Anime). Does 10bit+ not help even though there's an option in the Nvidia CP? I haven't really messed around with that yet.

Like lanczos 4 rendered by nvidia 930m appears sharper than rendered by Intel hd 5500?

that doesn't mean lanczos4 is a better choice. the math used on the image should have the same results. if it is different something else is the cause. |

AFAIK, ST60 specifically shows banding on grayscale gradient when 10bit/12bit option is used. I would stick with 8bit. On VA/SPVA/MVA panels, 12bit option helps, but Plasma uses dithering by default + you get madVR dithering, so its best to stick to 8bit.

Not likely. At least not in test images.

Found a performance bug in my setup with a fix. I was wondering why the rendering time on chroma was higher than it used to be in the past. It might be related to LAV 0.68.
Some numbers using a high resolution video playing in chroma upscaling mode only. In LAV Video settings- DXVA2 Copyback 1.6 ms DXVA2 Native 2.6 ms Yes, native was 1 ms slower than copyback.. which makes no sense to me, but that's what the HUD was saying. This is with the following checked ON in madvr options: use a separate device for presentation use a separate device for dxva processing Now, if you uncheck these options the rendering time in copyback jumps to 12+ ms. I have no idea what interaction is at play here but the rendering time difference is huge with those two checked and unchecked. |

Refresh rate change
Is it possible for madvr to do the ff:
1. If video frame rate is 24 fps then switch to display refresh rate to 48hz 2. If video frame rate is 25 fps then switch to display refresh rate to 50hz Thanks
