After some thorough testing a few months ago, my optimal settings for example turned out to be 6/20/20. Less or more than 6 didn't work properly and increasing past 20 didn't bring any added benefit (while 18 on the other hand was a tad too low). Now I never get unexpected drops after the playback has started. Last edited by Uoppi; 16th May 2016 at 15:45. |

double checked on aways 2x supersampling and aways when upscaling is needed, the image doubles, downscale but not apply the refinements no image changes and no render times changes even if check all the refinements on high remember you said one time that supersampling only actives upscaling refinements if screen resolution was the same as movie resolution... still not activating on my situation... i trie restore default settings uninstal, and copy the new version and begin from 0 but still the same behave by the time i have to use with only image enhacements with no supersampling, its preety good but has some distortions with ab enabled... thanks for your atention and again sorry for bother you and the others with this situation

Actually ringing is an artifact of sharpening of downscaled images.
For upscaling (chroma or luma) I don't think more than Bilinear is needed for accurate results. Anyone disagree and why?

So is image doubling not activating for you, if you select "supersampling" in the image doubling section? Or does it activate, but upscaling refinement doesn't activate? Quote:

Smooth motion FRC does need a moment to activate properly. That's just the way it is atm. It should only be a very short time, though, not a couple of seconds. Maybe your settings are too high so that the GPU has trouble keeping up? That might be partially responsible. Try lowering your madVR settings a bit to give the GPU more room to breathe. That might already fix the problem. Quote:

Yeah.
A simple interpolation is all that it takes for upscaling. You can't ADD detail that is not there, can you?

OMG, are you serious? Why don't you take a nicely sharp photo, scale it down to 25% with a good downscaling algorithm, and then scale it back up with madVR to 100%. Then compare Bilinear to the more sophisticated algorithms. If you think that Bilinear is producing the best quality (or comes nearest to the original image), then you need to go visit an eye doctor, and very quickly.

No offense of course, just some speculation.
Interpolation is for interpolation which always starts with nearest neighbor, sharpening and anti-aliasing comes on top of that if wanted or needed.

Nearest neighbor, linear and bicubic (and its variants) are interpolation-based, but upscalers like SuperXBR and NNEDI3 work quite differently.

and bilinear is pretty good at making the image extremely unsharp so it is not that "accurate". spline 3 is know to have pretty high psnr or was it gaussian? what so ever PSNR is just math and not subjective. i mean x264 can be used to achieve the highest possible PSNR but this usually doesn't result in a better subjective visible results. it is off by default for a reason. doom9 was down so i guess i'm a little bit late. |

Why do you feel the need to speculate at all? It's so easy to test it. Please do yourself (and us all) a favor and do the test I suggested in my previous comment. If you do that, you'll quickly see that your speculation is way off.

madshi, very small issue I have after every upgrade. I just want to get your opinion on it, as to whether to register it as a bug or not on madVR bug list.
After I upgrade versions, if I then launch a movie and go to fullscreen. If I then open the madVR properties via right click mpc-be window and open madVR properties, some sort of permissions dialog box appears behind the madVR window but I actually can't get to the "Edit Settings" section. Its like as if mpc-be and the "Properties" dialog are in some sort of modal setup where no combination of clicking Close / OK / Cancel / Alt-Tab can get me out of it. I have to kill with task manager or if I can't get to it which is the case right now, I have to reboot. Just not sure if its anything that be made so that it doesn't appear on each upgrade. EDIT: OK I reproduced in non full screen mode, and its Windows Smartscreen pop up thats saying its an unknown application. (Windows 10 64bit) Last edited by mark0077; 16th May 2016 at 20:54. |
