Sorry,it just does not look good on real time rendered content that already doesn't have good AA before downscaling. It's going to bring back the aliasing that a good resampling filter should remove. TW3's built in AA is poor, and 1080p to 720p is only a 2.25x factor so it's not going to look the best anyway. Quote:
Bad reconstruction because of a poor source file (Brings out the existing compression). I would have to imagine if the source was lossless it wouldn't happen. Having lossless SD content in a non-interlaced format is a pipe dream though. Last edited by MrBonk; 14th February 2016 at 10:21. |

And yeah, superres is likely screwing up the image because the source is bad, but even on pretty clean sources (2gb BR rips down to DVD resolution... though encoding settings and actual source may be much less good), I tend to see the same problems. |

0.90.9 seems to have introduced a new SSIM related bug at least in my system (Win 10 x64, Radeon HD 6850, Catalyst 15.11.1). When video deinterlacing is on and downscaling factor is such that, instead of downscaling the whole image, only luma is downscaled, something strange happens.

stuttering issue
Hi, ive noticed an issue that has appeared since i upgraded to the 90.x version: for HEVC decodes when i go full screen and match the content frame rate (to 1080p23) the video starts stuttering. This does not occur when the video is in a window and desktop is at 50Hz, and does not occur for x264 content.
I have noticed it in x265 videos ive watched previously (before upgrade) that didnt have this problem, but now do. Im using MPC-HC. Has anyone else seen this type of issue? |

madshi, bug report for you:
Using a 3DLUT, I'm getting some pretty bad clipping on particularly bright colors, and I think it's due to some precision loss in madVR. I say that because I turned off the 3DLUT, saved a screenshot, then loaded it up in MPC-HC and turned the 3DLUT back on, and the clipping is gone! I have all trade quality options disabled, though I did notice that enabling the "use 10bit" options shifts the clipping around slightly. Could you please take a look? Here's an archive containing the 3DLUT, a sample video, and several images to show what I'm seeing. With the 3DLUT enabled, I see clipping on the sky - the wrong colors look like the colors without the 3DLUT. I took a screenshot of frame 256 with ("video-frame-256-with-3DLUT.png") and without ("video-frame-256-no-3DLUT.png") the 3DLUT enabled to show the clipping. "saved-image-with-3DLUT.png" shows what I see if I open "video-frame-256-no-3DLUT.png" in MPC-HC with the 3DLUT enabled. I'm testing this in windowed mode, but I see the clipping pretty much regardless of the settings. It's visible regardless of chroma doubling, superres, D3D11 versus D3D9, the native display bitdepth or trade quality options. My graphics card is an Nvidia GeForce GTX 970, with the 361.75 drivers, and I'm on 64-bit Windows 10 (using 64-bit MPC-HC and 64-bit madVR). I'm using the latest version of madVR, but I've been seeing this for a long time - it's just different every time I do a new calibration on my monitor.

And can you please try to find out which exact madVR build introduced the problem? You can download old builds here: Quote:

Try adding this custom shader: Code:
sampler s0 : register(s0); float4 main(float2 tex : TEXCOORD0) : COLOR { return saturate(tex2D(s0, tex)); } Quote:

True, I tried to upload it but kept running into size caps and gave up. I can try compressing it a little more (or putting it on Mediafire / Mega) if you'd still like to see it.

Does the media player still react to mouse and keyboard events? Then a debug log may help. If not, a freeze report might help. |

Okay, I applied a quick dirty fix to the collink source. I'll see if it works, then post to the ArgyllCMS mailing list or something (my fix is very ugly, but also very simple, so it shouldn't be hard for Graeme to address if my fix works).

A little comparison for those interested in hardware, I recently acquired 980ti and a full unlocked fury(think furyx). They fury(x) is slightly faster(about 1ms render time, avg ~14 vs ~15ms) for one of my 1080i60 clip upscale to 4k with following setting.
980ti 1460hz Fury 1060hz 3dlut , banding on, order dithering Chroma : lanczo ar Luma nnedi3 32 Chroma doubling ( image upscaling used when nnedi3 chroma doubling is not used) Lanczo ar Upscale refinement, SR str1. Realistically, the performance difference won't matter for 24 or 30fps content, but 60fps content is really tight on performance. If anyone want test other comparison, please let me know, before selling off one of the cards. Sent from my SM-T700 using Tapatalk |

Actually, is a file format specification of madVR's 3DLUT files available anywhere? I'm a bit confused by some of the things in the collink source (in particular, are output values supposed to be stored in the range 0x0000 - 0xff00? I would expect a range of 0x1010 - 0xebeb for video levels, but that probably just shows my ignorance).

Anyone have an image preference? 720p to 1080p
