A couple of things; can you confirm the strength and number of passes you used for SuperRes and super-xbr strength please? I presume defaults but can't see it mentioned in your post. Also, is SuperRes only really intended for upscaled content or can it be used as a mild sharpener for HQ 1080p material on a 1080p display to help bring out fine details? |

That's much more complicated/difficult, I fear. E.g. Bilateral and SuperRes for chroma both look at the luma information, too. And studios might use anything from Nearest Neighbor Downscaling to Lanczos for chroma downscaling. |

I've been following this thread closely to see if any of the new algorithms could allow me to replace the Darbee. SuperRes looks like the best so far but I'm not sure if it works to improve the perceived sharpness of the projector like the Darbee does. Perhaps a touch of AS on top? |

I can't really say for sure. Just play with the various options and let your eyes be the judge. And please report your findings here, would love to hear how you like SuperRes, AdaptiveSharpen etc compared to what the Darbee does.

BTW at this radius, strength does very little 4 is a touch sharper than 1 and I prefer it at 4. Comparison sample upscaled using a 2x pixel resize. ORIGINAL NNEDI-256+SR-STR4-R0.66 NNEDI-256+SR-STR4-R0.20 Much more accurate to the source using SR at a radius of 0.20, lots of extra detail here all over. I have a new high standard... Having something is better than nothing.. might not be 100% accurate but *shrug* work with what you got. Last edited by ryrynz; 21st July 2015 at 10:46. |

I have one question: super-xbr and nneedi116,32,64,128,256 are only available in image doubling. If I use image doubling, downscaling image is obligatory used for my display (I don't have movie with exactly 50% display resolution). If I use jinc (jinc is only avalaible in image upscaling) in image upscaling, no need to use donwscaling image. Even with downscaling, is it better to use superxbr or is it better to use jinc withtout downscaling? |

http://madshi.net/clown.png I fear we may have to increase the radius to a value *higher* than 0.66 to get rid of aliasing problems. Sad but probably necessary... Quote:

Does an image that small really fit the bill as far as being comparable to typical use cases? Quote:
I do prefer the edges when using a higher radius but I'd rather have that detail there. I wonder if Shiandow could focus his attention on this particular area at all, a high radius SR utilized for edges only.. I dunno. Ugh, that's horrible. Last edited by ryrynz; 21st July 2015 at 12:33. |

Anyone is able to run CUVID Acceleration from LAV Video Filter with MADVR and not freeze and crash ? None and Write-Back works fine, just the mixed with Madvr + CUVID .

Using super-xbr, it's no more resource hungry either. |

Thank you madshi for taking time to write such a detailed post. It not only shows how good SuperRes is but also the ideal approach to do the testing. The confusion which I had about the absolute best upscaling method in madVR, given there are so many choices now, is cleared up.

I think so too.
on another topic. Anyone knows if random dithering in madvr 86 was with coloured noise? With madvr new versions if i untick colour noise i can see banding in the skin of a person in a scene. With madvr 86, evr and wd player that banding is not there. Last edited by David; 21st July 2015 at 12:41. Reason: I dont remember right know if it was with evr +16 bit processing and i am not at home to check it |

hmm , I don't know, I prefer the CUVID, I am just used to it. I have the issue when I use madvr+cuvid and only with madvr is the issue , EVR Custom present + Cuvid works fine |
