IIRC this is the article that led me to believe that DXVA would play nicer in mVR over 3.0:

Completely default madVR settings with madVR smooth motion enabled in Zoom Player. I also set my display to 60 Hz. I don't see any odd usage spikes in GPU, CPU, or IO meters. SLI off. |

Those all improve motion quality instead of picture quality which seems like a similar goal to me.
@madshi Is this something easy to implement and actually worth it? I like profiles a lot but I would like the ability to multiply in the if statement or maybe a single new variable instead, pixels-per-second. This would help a lot with lower resolution interlaced material, I want to set higher neuron counts for 480p30 than 480p60 but I also don't want very complex or numerous if statements. I could use the pixels-per-second instead of width, height, and deintfps so 480p60 would automatically use my 720p30 profile and 720p60 would automatically use my 1080p30 profile. |

First and last aren't exclusive to madVR. Pretty much any decent video player will have them, including MPC-HC out of the box. Smooth motion does more harm to the picture than good (IMO). I use IVTC all the time, very handy. Anyways...

i just upgraded my GPU from a 5750 to a 280x but my motherboard is a PCI-E 2.0 and when i tried NNEDI3 "64 neurons" it cant handle it but its ok at "32 neurons", material is 1080p24 High-Bitrate and ffdshow is set to output 16bit P016. Could that be that my PCI-E is to slow? Do i need to upgrade? I'm very bad at all this but i really try to learn..
lost frames seems to be way better with P016 then at RGB32 if that makes any sense..... but i get artifacts in windows when i use P016 and NNEDI13.

madshi, what are your thoughts on using sharpening filters in combination with nnedi doubling? nnedi gives a very nice, sharp, artifact and ringing/aliasing free picture, but I still prefer a bit more sharpness for 720p->1080p scaling. I'm using LumaSharpen at very low values pre-resize, just enough to take out the little bit of softness that is left over from upscaling, nothing more. I think the picture looks pretty much perfect, but I'm wondering if this works against nnedi at all or its just one of those things "do what you think looks best".

@StinDaWg:
When you sharpen something, you basically add ringing. Other than that, it's all personal preference. Personally, I always use luma doubling in combination with Lanczos 8 AR, which gives me an incredibly sharp and still mostly artifact-free result. I'm also using 1080p as an output device. |

NNEEDI is it's own algorithm, but in combination with Lanczos 8 AR, you get the sharpest results, because Lanczos 8 AR is very sharp to begin with. That's only for upscaling purposes though, I still use Catmull-Rom linear light for downscaling.

I tried L8AR/CRAR and L8AR/L8AR and still prefer using LumaSharpen pre-resize. It takes out the softness better than Lanczos scaling alone. One thing is for certain though. nnedi is way better than Jinc when it comes to sharpness/ringing/artifacts.
I'm using Code:
#define sharp_strength 0.5 #define sharp_clamp 0.05 #define pattern 3 |

With madshi's AR algorithm, possibly even NNEDI could be improved, which I suggested before. But we would need to test that. And yes, I also prefer NNEDI (but NNEDI only works for powers of 2) > Lanczos AR > Jinc AR. But I expect that to be highly dependent on the content and your display setup. And of course, your personal preference. Last edited by iSunrise; 23rd March 2014 at 17:30. |
