Hi.
I have something strange with playback. My main GPU is Intel HD3000. I also have Nvidia 210 in the PC but it is not connected to the monitor. I am using MPC-HC x86 1.7.10. The choma scaling algorithm is set to default SoftCubic but for some reason it does not work as well as other scaling options. When I am watching 8-bit video (i.e. NV12 colorspace is used), I always get DXVA chroma scaling in the stats instead of SoftCubic or whatever set in settings. This DXVA scaling gives ugly aliasing and moreover it changes matrices 601-709. I got this http://grab.by/Rufs and this http://grab.by/RufG In my old PotPlayer everything is OK. My previous madvr 0.87.10 acts well. |

Rendering queue is sometimes hitting a ceiling of 8 max, even though I have set it at 20. Is this a known issue?
I remember there's been reports along the way about rendering queues not filling but this probably only started happening to me with the latest madvr version (v.22). If I either 1) stop and restart the video or 2) skip forward (and probably backwards too), the rendering queue is filled properly to max again. I have GTX 960 with latest drivers + Kodi DSplayer. |

Is the present queue near empty? Really, in all these situations a screenshot of the Ctrl+J OSD helps. |

What I've tested (not much): 1. At 1:1 scaling factor, render times are the same between the two versions. 2. At any scaling factor, the effect of the chroma scaler shows no differences between the two versions. 3. ED dithering isn't accidentally on. Neither are any of the image enhancement options. 3. Something in the image upscale chain (sxbr > bicubic 150 down > Superres) seems to cost way more with this version. Last edited by har3inger; 16th July 2016 at 19:33. |

Because all the names are not clear, it's hard to draw final conclusions. But e.g. if I compare your "3 SR1 no AB 4X.png" image with "3 AB75 4X.png", then I think the first one (without AB) looks better with less noise around the edges, especially at the bottom left part of the image. |

I forgot to ask, what does madVR do with BT.2020 input when you specify 1. "this display is already calibrated" for BT.709 primaries vs. 2. "this display is already calibrated" for BT.2020 primaries and is it the same whether HDR processing is on or off? |

I don't really understand how you could disagree that the top left corner on this picture with SR@1 doesn't look edgier without AB25: http://screenshotcomparison.com/comparison/178293 Ultimately, I guess the previous posts with the guitar make a better point than my pictures as SR without AB in mVR looks way too sharp and edgy to me and I might not be the only one who thinks so for that matter. I use SSIM 2D 100% for downscale and I was refining SR after every 2X upscale. I fully realize that SR is still a work in progress but I have never found any use to its AR subsetting when OTOH the AB one is vital to me. But I must admit that Shiandow's result with his own version of SR looks very impressive as in not overly sharp and very natural looking, I'd love to give it a shot if any possible please Last edited by leeperry; 16th July 2016 at 22:27. |

Requested screenshots
Hi, Madshi, my apologies for the delay in posting these:
madVR v09.90.20 madVR v09.90.21 Now, the settings are the same in both cases: Chroma upscaling: super-xbr 150, AR on, SR 3. Image downscaling: SSIM 1D 50%, AR on, linear light on, anti-bloating on 100%. Image doubling: always if needed, super-xbr anti-bloating 100 Image upscaling: Jinc, AR on Upscaling refinement: sharpen edges 1, thin edges 1, enhance detail 1, anti-bloating 100%, AR on, SR 1 linear light AR on. I hope this will be useful to you. Please let me know if you need more info from me. |

With HDR BT.2020 content, it's almost the same. However, the BT.2020 -> BT.709 gamut mapping is performed in much higher quality. It's on my to do list to perform the higher quality processing also for SDR gamut down-conversions. Quote:
So here we go: SR2 AB75 SR1 no AB Although the images don't have exactly the same look, they appear reasonably close, with the SR1 image having less noisy edges. Based on this one test image, I'd prefer SR1 over SR2 AB75. Wouldn't you? Quote:

There was a user who complained about upscaling refinement settings not becoming active when upscaling by a relatively small scaling factor. I've changed that, which will of course slow things down if upscaling refinement suddenly becomes active when it didn't before. |

Well, screenshots are one thing, how AB fares in combination with FRC in 60Hz motion another, basically SR1 doesn't look sharp enough and SR2 too sharp. AB gives SR an analog look and does exactly what you initially said: "The new anti-bloating tries to concentrate sharpening on higher frequencies and to remove lower frequencies. I like the look that produces, but your mileage may vary". I -and others- like the look that it produces, we like how it sharpens higher frequencies and removes lower ones BUT if you really wanna compare SR1 and SR2 AB75, only 4X zooms make sense to me as I run a 32" TV from a 1 meter distance: http://screenshotcomparison.com/comparison/178799 Apart from the top left corner I far prefer the SR2 AB75, it even makes the shadow in the bottom left corner lighter & closer to the ground truth, very obviously less bloated™: http://screenshotcomparison.com/comparison/178801 http://screenshotcomparison.com/comparison/178802 Quote:
Maybe the OP would be able to provide it, but it seems rather hard to deny that mVR's SR looks way oversharpened in his example IMHO. I'm certainly not interested in such a sharp image myself, and neither would be others as it would appear. Apparently the only way to try it would be that MPDN thingie but I've never used and I have no interest in learning as it seems tied to MPC. Last edited by leeperry; 17th July 2016 at 02:38. |

Any RX 480 users here? Id like to compare my rendering times on 7870 to the new card! Mine could do 1280x720 24FPS video to 1080p with luma doubling 64 NNEDI3, smooth motion, error diffusion dithering and low/high debanding with around 35ms rendering time. Trade quality for performance - all unchecked. Win 7 Catalyst 13.12 driver.

SuperRes turned on: http://i.imgur.com/3khJ82K.png http://i.imgur.com/p6JGGyZ.png SuperRes turned off: http://i.imgur.com/57jtmWP.png http://i.imgur.com/IwiMxG6.png heck, even did a gif switching sr back and forth to show changes: https://gfycat.com/FloweryIdolizedCaterpillar In HDR processing everything turned on, preserve hue is on high and peak luminance is at 400 nits. Having different chroma upscaling, image downscaling, doubling, image upscaling algos has no effect on image color shift including turning on or off superres in upscaling refinement, only turning off superres for chroma gets rid of color shit. |

Sorry for the no screen shots madshi... but as Iznogūd posted, the screen shots wouldn't have made much of a difference since they are the same except for the performance hit... I plan on doing some testing of the upscaling refinements myself but work has not let me... and I am about to leave soon for my first Saturday night out in what seems like years! LOL... Hopefully tomorrow, I will have plenty of time to test this performance hit. I'm just glad I'm not the only one who sees it. Although I think I'm the first to report it since I always push the GPU to the max on my 720p content (which is what I mostly watch) and the slightest performance hit will always push my GPU over the edge.
QB EDIT: p.s. Is there anyway to create a debug OSD that will show every setting being used? Even if it covers the entire screen... something we could use to narrow things down for you, and provide more detailed SS's. It could also be useful for hardcore users to tweak their own settings

No screenshots for the OSD for now, but literally everything in it is the same, except render time (35ish -> 45ish) , and the render queue emptying slowly over time.
I have no upscale refinement algo's checked except SR (which is definitely on in both cases), so it shouldn't be that, unless one became forced on regardless of the UI setting. |
