Would it be possible to add an option for no scaling at all in the auto A/R settings? I don't want any zoom or scaling to happen, and in some instances - for example when playing a test pattern for chroma multiburst from the S&M bluray which has a small black border all around the pattern - some scaling is applied which destroys the picture. This happens even when I select the maximum (50 pixels) as in this instance the border is slightly larger than that.
When using the great auto A/R feature on a 16/9 screen to shift the picture up or down depending on the A/R, there is no need to ever scale or zoom if you don't want to zoom the black bars out. I don't want to do that because it's detrimental to the PQ, but there is no way to fully disable this at the moment, or I've missed it. A pure "no scaling" or at least a 100 or 200 pixels option in that list would be great to make sure scaling/zooming is fully disabled if we don't want any in any circumstance. Thanks! By the way, while looking at this pattern (once I had solved the scaling issue), some of the new chroma upscaling algos fail this test. For example, reconstruction soft fails and Super-XBR above 75 significantly raises the brightness in a way which can't be good or accurate, even if it does look sharper. So based on this test, I wouldn't use reconstruction soft or any setting for super XBR above 75 (maybe 100 pushing it, but I would suggest 75 to be safe, unless you favour sharpness at all cost). Sticking to NNEDI 32 for now with super res at 3 as I can spare the power on bluray, and as I couldn't find an alternative that looked better both with patterns and real content.

And you're right. Turning off the image doubling does fix it. Last edited by evil-doer; 23rd February 2016 at 01:01. |

Doubling 1080p with NNEDI3 and downscaling back to 1080p gives interesting results. I found SSIM 1D to look better than 2D, and definitely needed to utilize SR under upscaling refinement's to make it worth while.
Crispen edges and line thinning might be worth playing with in small doses. I didn't try Enhance Detail. Other sharpening refinements gave VERY subtle results. Sorry if I don't have the lingo to explain things better. It seems like very fine details were a bit "smudged" compared to not supersampling. I'm not sure if this "smudging" is a good thing that helps with aliasing, or bad as it could be considered an artifact. I'm inclined to avoid supersampling until I can do more testing, but it's an exciting new feature. Thanks madshi! |

@ Georgel:
I just read your guide... I think you should go more in depth with some options and you should explain, why you are using this or that option and what would be the good/bad of using it. Asmodian got a good collection of madvr options with good advises here: http://forum.doom9.org/showthread.php?t=171787

Thanks a lot! I looked these things over, and changed them. I will try to improve the guide as much as I can and as often as possible, because my software for video playback will rely heavily on madVR compatibility for video to look great.

I will look into it and update the guide as soon as I can with all the information I see there that might be of interest. If you have something specific that you want me to change, feel free to tell me.

I love the Auto A/R feature of MadVR, so I don't want to disable it, I would just like a setting/option in the auto A/R settings that guarantees no scaling or zooming whatsoever. I don't mind if it shifts the picture up as that's what it was designed for in my case, but I don't want any scaling/zooming to ever happen, whatever the circumstances. With the existing settings, there is some scaling/zooming if the black bars are larger than 50pixels, as this is the largest setting allowed currently.

Because I don't need any zooming or scaling for it to work perfectly on a 16/9 screen. MadVR shifts the picture up to get rid of the top black bar, and I use a physical mask to mask the lower black bar on my projection screen. There is no need for scaling or zooming, and I don't want any. No one with a 16/9 screen needs zooming or cropping when using the auto A/R feature of MadVR. It's a great feature though, it prevents me from using the physical shift of the projector which takes ages and wears motors down, plus is limited to a few presets while MadVR is always perfectly right as it detects the actual A/R very well (except when there are also small black bars on the sides).

Hi,
I asked to my TV manufacturer what is the best video input signal on TV, they answered to me it's YUV for the following reason: Quote:
I'm not agree with us as MadVr and video cards aims to work with RGB video signal. This avoid multiple video conversions during the processing and only the TV have to do a RGB to YUV conversion at the end. Guys, what do you suggest regarding GPU video output (madvr is grised out on RGB) ? YUV or RGB ? Quote:

i don't see a reason RGB shouldn't work in this case madVR takes care of the rest. |

This thread is the first google result when searching for madVR, and I had a very hard time for 2 months until I understood madVR, what it does, how and how to use it. This is why I want to point people to a thing I strongly believe will help them. Also, I changed it according to all advice I had received from everywhere, so now it should be even better. About reporting bugs, for me, with a GTX860M from Nvidia, using the settings that are pictured in there, if I activate Direct3D11 and full screen exclusive mode it will crash when going to full screen. It does this every single time I try to go to full screen. From what I understood, after madshi took a look into the file I got from the crash, it seems that the driver is problematic, and it is not a madVR problem.

only when NNEDI3 doubling/quadrupling is enabled and only with one video I have at which has a 704x480 resolution. Last edited by ryrynz; 24th February 2016 at 00:19. |

The problem with most of the guides is afirmations without explanations, I started using madvr with a guide that has a lot of wrong informations, for a beginner this is bad because we tend to believe on guides Did you reads the thread madvr options explaned? You should try to explain the configs and if you want talk about your preferences as personal preferences Like the topic about image refinements and upscaling refinements, is simple wrong and not explained... Doubling and chroma upscaling too
