UHD->FHD chroma conversion bug introduced in 0.90.16 (0.90.15 works fine), from OSD:
- scale 0,0,3840,2160 -> 0,0,1920,1080 - chroma -> Catull-Rom Where it shouldn't apply any chroma conversion in this case.

Im using version 0.89.17 and have some questions....
Im playing at 1080p > 1080p and using the JVC RS600 projector, video card 970 1. Is there a page I can look at that has an explanation for every setting please? 2. I play a lot of clips from Youtube which could be 720, 480 sometimes worse.... What are the best settings for getting these to look as good as I can please? Tidy up macroblocking, softness etc etc.... Is this area just in upscaling? Thanks in advance... |

The best you'll get until then is probably this: http://forum.doom9.org/showthread.php?t=171787 If you looked you've probably noticed madVR doesn't have a deblocker (yet?) so you'll either need to preprocess with ffdshow, or make do. Not sure what this really means, but you must have seen the "image enhancements" section by now. |

problem occurs only in windowed mode, all is well in FSE and that's with NNEDI3 luma doubling only as enabling it for chroma as well fixes the problem:
sample video and settings.bin available at https://mega.nz/#!D0IinBxJ!nv5b36Oqk...6YHjeBRh2bMCKc I also got 720p videos that give the exact same problem but only in FSE this time. |

Have had a number of issues changing queues in madVR over the years, this one kicked me out of the desktop and back into the sign in screen under Windows 10 after some graphics glitches
I changed the full screen and windowed mode frames presented in advance from 6 to 16 and the CPu and GPU buffers from 8/12 to 20/16 and then attempted to continue playing the video. I had to reboot because the graphics driver wasn't stable after logging back in. Seems the queues are simply too much for the old HD3000 to handle, those settings force Windows to do as I described every time I try to play something. Setting them to 8/8/16/12 works fine.

I was testing profiles. I made it very simple. The first with sharpening the second without.
But I ran into issues with the hotkeys. First madvr didn't want to accept my shortcut falsely claiming it's invalid, because it used a character with a diacritical mark. On second try I added alt+q and alt+w. Which were accepted but didn't work at all. |

As for the difference between Crispen Edges and AdaptiveSharpen+AB, I think Crispen Edges has the drawback of emphasizing compression artifacts, whereas AdaptiveSharpen makes things look like a watercolor painting at higher strengths (AB does a lot to reduce this effect). I'm pretty sensitive to compression artifacts, at least on still images, so I tend to prefer AS at fairly low strength, but I'm not sure I could find a combination of settings that works well for all (or even a large subset of) the videos I watch. It's fun to play around with for low quality videos though!

When you use Linear Light downscaling, this usually happens.
There is a new "trade quality of performance" option, called "scale chroma separately, if it saves performance", maybe try that?

I have a couple of examples of where anti-bloating removes detail that would be considered valid sharpening.
SD -> FHD super-xbr100 + SuperRes (3) Edit: Updated links to Google Drive. In the first example, search for the headline "Rick Nielsen: no cheap collector" in the middle of the image. SuperRes does a good job of making the original letters more clear and easy to read. While anti-bloating returns these letters to a blurred smear. The rest of the lettering, especially on the lower part of the guitar shows the same improvement and then degradation when anti-bloating is enabled. Guitar Guitar SuperRes (3) Guitar SuperRes (3) + Anti-Bloating 100% In the second example, look at the leather patches on Kata Mara's arm and the black guy. Also, the objects in the shadows (top-right) become obscured when anti-bloating is enabled. SuperRes again slightly enhances the low-res original and anti-bloating effectively cancels this out. Fantastic Four Fantastic Four SuperRes (3) Fantastic Four SuperRes (3) + Anti-Bloating 100% So far, only my original test where SuperRes (3) was combined with crispen edges (1.0) did anti-bloating prove to be an effective countermeasure for SuperRes. I am thankful to see that SuperRes, at the right strength, does not oversharpen the image. This has completely changed my settings preferences.

- 'scale in linear light' under image downscaling is unchecked in the profile (checking/unchecking doesn't make a difference) - if I check 'scale chrome separately, if ...' then indeed chroma conversion vanishes (so maybe this new option brought this bug, if it's a bug) My Zoom control settings for 4k (maybe it also affects something): - 'disable scaling if image size changes by only' checked: 50 lines or less - 'move subtitles' checked: to bottom of the screen/window - 'auto detect hard coded black bars' UNchecked

Superres with antibloat at or above 100% completely eliminates the aliasing/blobbiness/chunkiness SR introduces to low resolution content. Unfortunately, it also makes it appear that superres is doing almost nothing except introduce artifacts on hardcoded subs and similar scene details.
For low-res bad quality content, SXBR AB25 looks quite similiar to nnedi64. There's a bit less sharpness, but similar reduction in source artifacts. Considering the cost, that's pretty damn good. Any higher AB and SXBR starts looking too soft. Using AB on SXBR followed by SR with AB checked can tend to produce odd looking images. I'm not able to take or upload screenshots for a while unfortunately, so I can only leave these impressions here. It'd be really great if someone could try to reproduce and see if they notice similar issues. What quality tradeoffs are present when we check "scale chroma separately"?

Well sounds to me like this option is designed to allow just what you want, scale chroma straight to the target (which in this case is no scaling at all). But madshi can say if it works as intended.
