"screenshot proof"? I don't think there is such as thing as a "ground truth" concept when it comes to subjective settings such as sharpening? Otherwise there would be no strength option to those four new features to begin with? What would change your mind exactly? Using a 1080p reference, downscaling it to anything using 960x540 using CR AR LL and then showing differences with 2X SR checked? I just did a whole bunch of A/B comparisons on DVD'ish-resolution noisy movies in .13 with sxbr25+SR(St4/Sh2/R0.66) and I far prefer having 2X SR checked because it does look like double SR filtering to me, I mean I do get double-SR and high motion looks less edgy and a whole lot smoother(30fps@60Hz with Reclock) when the option is checked. You admitted that 2X SR might make sense when other sharpening refinements are checked and it would make total sense to me to have SR pick the best looking frames after every 2X upscale, I think an extra checkbox as to whether the end-user wants SR going 2X as well would make perfect sense. NNEDI3 is the real GPU hog, my HD7850 doesn't break a sweat when 2X SR is enabled and either way the PQ improvement totally warrants the extra GPU load(which is very low anyway). I'm far more convinced by 2X SR than the four new features tbh because SR is just much more technically advanced to my eyes, ensuring that only the best frames are selected instead of trying to polish a turd so to speak. I'm not interested in what "sharpen edges" and "crispen edges" have to offer, "thin edges" might be worth looking into and I'm not sure about "enhancing details" yet but then again I've never been interested in regular sharpening filters, I only like SR because it's a lot smarter than a regular sharpness knob and it looks outstanding in motion. Long story short 2X is totally worth the extra GPU load to my eyes, at least with Reclock on a LCD screen and "thin edges" might allow sxbr to look thin like NNEDI3. |

All I want is some screenshots that show that running SuperRes after every 2x upscaling looks better than running it only once. That's all. No ground truth needed. |

next file is not properly played
When next file in a directory is played then the audio is played only. The video freezes at the previous file. I mean, I have several files in single directory. I use mpc-hc with option to play next file in the directory after playback of the actual file ends. When the next file should be automatically played then the audio starts correctly. However, the video freezes at the last frame of the previously ended file. The same happens when I skip to the next file manually (video freezes at the last played frame of the previous file). I found out that this started with madvr 0.89.13. It is present in all subsequent releases 0.89.14-16. The problem is not present in 0.89.12. I started having the problem while running mpc-hc 1.7.9.190. Now I use mpc-hc 1.7.9.202 and it makes no change. I also use reclock 1.8.8.5. All software is 32-bit, running on Windows 7 64-bit (running geforce drivers 358.91, problem was seen also on 358.50).

We are indeed back at the "it looks more or less the same" argument on your part but again at this rate a lot of options in mVR are redundant, especially when it comes to chroma. 2X SR doesn't look "pretty much the same" by a long shot with noisy SD on my rig and you agreed that it made sense when extra refinements options were enabled so I don't understand why the sudden decision to disable it So if I enable 0.1 "thin edges", I get 2X SR? I guess I could live with that. And we're also back at the argument that I'm big enough to run scripts on my side(lucky me I don't have to justify my VST plugins chain in ffdshow to anyone) and that I'll have to waste time proving my point again when the difference is *very* obvious in motion on my rig and that this option had been there since the beginning for a good reason. Oh well, as a ground truth isn't needed this time I'll try to find noisy material that shows cleaner edges with 2X SR. Last edited by leeperry; 11th November 2015 at 14:03. |

But what can be the difference at the viewer's point? I mean we already modified the gamma on the TV to 2.4. Quote:

why do a double gamma correction that shouldn't even fix issue like that? and don't even assume you get the gamma you setup in a TV. without calibration and a meter you don't know what you get and you can assume you have more of an S curve gamma than anything else. for a dark room you should aim at 2.4 anyway.

I have a Samsung S24D390HL display which has a AD-PSL. The panel is not able to support 8-bit colors natively. It does 6-bit + FRC from what I read.
What am I supposed to choose under "Device->*->Properties->The native display bitdepth is? 6-bit I guess? If this is the case. Isn't there a conflict between madVR's dithering (which obviously is better) and that FRC dithering the monitor does automatically? I also guess I'm not able to deactivate the latter? |

I have an HP Stream 7 tablet that I very seldom use. This weekend, though, I'll be watching a couple of movies on it. The processor is an Atom Z3775G quad-core, and the unit runs 32-bit Win 8.1. I can run MPC-HC using QuickSync for decoding, and madVR works at the default settings (looks pretty good, too). Being a tweaker, though, I won't be satisfied until I see how far I can push this chip.
Assuming I can only make a few settings changes in madVR until I start dropping frames, what changes are likely to give me the most improvement with the least cost? The screen is 1280 x 800 and the movies I'll be watching are SD. Doubling is probably out of the question, so what else should I try to tweak? |

With some old interlaced DVDs I now have some repeated frames (no drops) while using smooth motion since madVR recently introduced automatic switching to DXVA scaling for both chroma and luma when deinterlacing. Does this mean it's a NVIDIA driver bug or still a madVR one?

Smooth motion is really good, and is probably going to give you the biggest boost if your monitor doesn't support 24fps. The jump from SD->1280x800 isn't too big, so jinc AR for luma is probably sufficient and not too different from what doubling would produce. I don't think you can run SuperRes, but if you can, that's the next thing to try turning on. Use bicubic75 AR or jinc3 AR for chroma if you can afford it. Checking on 10 bit image/chroma buffer in trade performance for quality is unlikely to result in any visible difference. Those would be worth using for you as well. Disable linear light for dithering is also fine, but I'd leave linear light on for smooth motion because it makes a big difference there. Ordered dithering is great, and you should use it since it's better than all the alternatives for you. Debanding can help immensely for sources with banding (obviously), but can cost a bit. Depends if you think your videos need it. |

All pictures as a .zip file, using .13 with sxbr25+GL SR(St4/Sh2/R0.66), no other refinement was checked and I didn't try LL. Dithering was disabled. The cleaner edges provide smoother motion, kinda dreaming of 4X SR now tbh and SuperSampling too while we're at it New GPU's will be out soon and I'd happily use them for outrageous SS SR.

Hi all,
I'm experiencing a strange v-sync issue with madVR. In a two monitors setup if I have one or more applications open that use madVR after a random amount of time I start experiencing loss of v-sync in other applications. To restore v-sync I have to minimize or close all the instances of the applications that use madVR. Then, if I reopen some application that use madVR, after some time it happens again. I clearly experience image tearing with applications like VMware Workstation, Outlook 2010 and VLC. Strangely applications that use madVR aren't affected. Below more details. OS The most important thing that I observed is that this started to happen just after upgrading a few weeks ago from Windows 8 N to Windows 8.1 N, both x64. On Windows 8 I had installed the Media Feature Pack but on Windows 8.1 I hoped to do without it so it isn't installed. GPU I have a GTX 680. I currently am on driver 358.50, but I tried various previous versions with no luck. I changed some settings in the Nvidia control panel but this didn't help either. Monitors Initially I had one monitor connected via DisplayPort and the other via DVI (digital dual link). Now they are both on DVI but it doesn't help. Both monitors are 1920x1200 @ 60 Hz. Nvidia control panel shows 60 Hz, Windows says 59 Hz and madVR something like 59.95 Hz. From what I understand this is normal. If I use only one monitor there are no v-sync issues. It doesn't seem to matter on which monitor the applications are shown. Software I'm pretty sure the issue is triggered by madVR because it happens if I have open instances of DVBViewer Pro and/or MPC-HC, both 32 bit and using madVR. Also I tried VMR 7 and 9 with apparently no issues. I can't try EVR because I'm on an N edition of Windows. I'm on madVR 0.89.16. Again I tried different settings and versions of madVR without finding a solution. I also tried using another video decoder instead of LAV Video (32-bit, v0.66) but the issue remains so I really think that this is triggered by madVR. I looked at madVR's OSD both when the issue is present and when it isn't and I couldn't see any relevant difference in stats to get a hint about what's causing the issue. At this point I really think the only things that I could try are to install the Media Feature Pack for Windows 8.1 or get another GPU. I'm not too fond of the first option because I'd like to keep my system as lean as possible. And I'm quite satisfied with my GTX 680. If anybody has any suggestion or wild guesses it would be really appreciated, thanks. |
