Now that we moved on to Image Refinement, may I ask - what exactly is the different between LumaSharpen, FineSharp, and SuperRes? I assume they deal with increasing sharpness, which is a bit odd because AFAIK madVR was all about making the image as soft as possible. I guess overwhelming popular requests for these options made them possible, especially the LumaSharpen option.
I tested default settings LumaSharpen (Image Enhancement) and default settings FineSharp (Image Enhancement) with both HQ and MQ content, but I did not like either at all. Both features made dithering, noise, blockiness, banding, or artifacts more obvious/visible/emphasized in MQ, LQ, and even moderately HQ content. Its like these settings canceled all the madVR's image improvement through softness. LumaSharpen and FineSharp were only helpful in absolute best HQ content (full BD's, not rips). I have not tested LumaSharpen and FineSharp Upscaling Refinement. SuperRes as a Chroma Upscaling filter and as Image Refinement option seem to improve overall image quality, making it slightly sharper, but without emphasizing the blockiness, noise, dithering, artifacts, or banding in LQ, MQ, and HQ content. I wish I knew exactly what SuperRes was doing (without getting too technical) so I could look for those specific effects. |

SuperRes is very expensive on the GPU so I definitely can't run it more than once. For me, it's only working on 288p videos with 1 pass, and I have to say I love the result. it greatly enhances the image of low-quality videos. If quadrupling resolution, would it be better to run SuperRes twice with 1 pass or once with 2 passes?
The TV already has image enhancing features so I'm disabling those when the output is the TV, except SuperRes for 288p videos. When displaying on the laptop screen, I like LumaSharpen but find FineSharp too strong. This is useful for low quality videos and low quality videos often have bad artifacts. Sharpening amplifies the artifacts. Again, I love SuperRes but it is expensive to run, and somehow it is much more expensive than it should on 480p videos.

With 88.11 mpc-hc the queues emptying and will NOT filling back up after I seek, thus the videos stuttering after seeking.
I need to pause or exit full screen (not FSE) to "refresh" the queues. EDIT: Sometimes it happen all by itself without seeking. EDIT2: *On secondary screen only!

here my founds about superres so far.
superres can make bilinear into a ok resizer. i never saw a picture where anti ring even at 1.0 would harm the picture. i totally love it! anti aliasing can create out of place pixels when set over 0.30. i'm not a huge fan of it. finesharp: i don't like the results of it. it is simply not neutral on my test even at weak strength. lumasharpen: lumasharpen can create ringing/holoing when the radius is over 1.0. but i think it is very useful at radius 1.0. i currently use these settings upscale refinement: LumaSharpen: S=0.70 C=0.035 R=1.0 no limiter SuperRes passes 1 quality medium (i never saw any benefits from high) strenght 0.40 sharpness 0.25 softness 0.25 anti-aliasing 0.20 anti-ringing 1.00 upscaler is currently jinc 3 LL AR. |

My thoughts about SuperRes and LumaSharpen under upscaling refinement.
LumaSharpen at default setting works real well , gives video a bit more pop. SuperRes works well, especially with upscaled standard definition vidoes and I currently have it set to medium with the following...: passes 2, strength .40, sharpenss, .25, anti-aliasing .25 and anti-ringing at 1.0 Setting SuperRes to high shows a slight improvement in picture quality but at a high cost of around 10-12 milliseconds in rendering time so I just keep it at medium. |

For AMD users who have slower NNEDI3 with the drivers newer than 13.12, put these two dlls in your MPC-HC x64 folder and see. They're from 13.12 package I stored before moving from it to 15.5 beta.

I honestly am not noticing much debanding in the videos.
Shiandow's debanding algorithm seemed more to be an image enhancement than a debanding algorithm. It was doing a pretty good job without being expensive, but I'm not sure what it was actually doing. Shiandow produces a slightly sharper image in a way that looks more natural and neutral than FineSharp.

That being said SuperRes works quite well with good 480p and up material. With a good DVD (Friends Box Set) it can improve the image quality rather nicely even at default settings. (EDIT)I forgot to add that SuperRes works quite well for Chroma with Jinc. It makes the colors crisp and distinctive without adding any artifacts I can see regardless of the resolution. Also when upscaling I actually prefer using SuperRes each time the image is doubled. It seems to improve perceived sharpness better that way.(EDIT) I've pretty much stay away from LumaSharp because for me it tends to introduce too much aliasing at strengths it looks like it is doing any good to me. MadVR's version is no exception. Not to say LumaSharpen is bad by any means. I use it a lot for video games . It just doesn't do it for me with video. Finesharpen is actually pretty nice for me with scaling 720p to 1080p. It adds just enough subtle sharpening to make a difference. This is all for upscaling. I prefer not to use any sharpening for downscaling on the rare occasions I have to downscale.
