Did you try resetting madVR to default settings, and see if the problem still exists? Have you scanned your system for corrupt/mislinked filters/codec using something like the codec tweak tool? If not do so, fix any errors it finds, and to be on the safe side you can also tell it to associate default codec/filters. Sometimes disabling decoders/filters/codec doesn't really stop them, so you may have to uninstall the strongene decoder you reported installing.

video chain question, again......
Is this the best (and even more imporant: correct) video chain when my main purpose is Blu-Ray movie playback: Blu-Ray .m2ts file Device properties in madVR on PC levels (0-255) the native display bit depth on 10 bit (or higher) LAV filters video settings: RGB output on untouched (as is) display device (Epson TW9200 projector) on EXTENDED |

best is pure PC level if your end device supports PC level properly. i only heard that some panasonic supports PC level but the results are bad with banding for what ever reason. |

Interestingly, my ST50 doesn't have banding issues at PC levels.
About chroma scaling: There are very few scenes / movies where I can actually see a difference. One of these is the following example, where the chroma coding is atrocious (don't ask how it turned out to be like that). I think this demonstrates the potential in Bilateral quite well. Interestingly SuperChromaRes makes about no difference here (And neither does Bicubic vs Jinc, softcubic does make aliasing better but at 100 it starts to bleed out of edges too). |

I reported an issue a while back with duplicate frames being displayed after "excessive jumping" in MPC-HC with madVR used as renderer but nobody else seemed to have experienced it. Now I have pretty much pinpointed the issue: it is caused by madVR's smooth motion and for me it is 100% reproducible with AVI and WMV files (doesn't seem to happen with MP4 and certainly doesn't happen with MKV). When I jump through a video multiple times consecutively using MPC-HC's built-in jump backward/forward shortcut keys and then stop, sometimes after less than a second some, frames are displayed that are clearly from a different scene. Disabling smooth motion eliminates the issue regardless of container. This doesn't seem to be decoder/splitter-dependent since I can reproduce it with every combination of ffdshow/LAV as decoder and Halli/LAV as splitter. This also isn't hardware-dependent since I experience this issue both on my laptop with GTX 850M and my desktop with HD7950. OS is Win 7 SP1 x64 with madVR and MPC-HC x86.
Steps to reproduce: 1. Play a WMV file with madVR used as renderer and smooth motion set to "always". 2. Start jumping back and forth in the file using MPC-HC's built-in shortcuts 3-5 times and wait for one second or two between each jump (jumping forward seems to work best). 3. Stop jumping and watch the video carefully. 4. After 1-2 seconds you should see some random irrelevant frames on the screen that last less than one second and might repeat again after a few seconds.

Is debanding suppose to be so performance intensive? With it off, my rendering time is 10ms. With it on high/high (or even low/high), rendering time is at 30-31ms. Enabling 'don't analyze gradient angles for debanding' drops the rendering time to 20ms.

Also, what is the recommended hardware decoder to use with madVR in LAV video settings? Last edited by SecurityBunny; 5th July 2015 at 09:46. |

DXVA2(native). Or NVIDIA CUVID. DXVA2(copy-back) I only use for 10bit h265 60Hz videos ,which is not the case for your card because it doesn't have full hardware decoding for h265/HEVC.
I have GTX 960. NVIDIA CUVID is working the same as DXVA2(native) in terms of CPU usage(very low on both) but somehow it gives weird colors ,for instance skin color tones are a bit reddish and less detailed. Edit:For Kepler cards 347.88 is still the best driver. The last drivers seems to work good(well ,some of them) only for Maxwell cards. I have a gt 640 on another rig and the latest drivers(since 350.12) are causing issues of all kind. Last edited by edigee; 5th July 2015 at 10:09. |

But why would you want to do this? The GPU should choose a higher clock fast enough. Quote:
However, maybe you don't want to enable it for 4k since the Kepler VPU isn't fast enough for 4k with high bitrates. |

cuvid does technically the same as dxva copyback it just force the GPU in high powerstate which totally beats the reason to use a harware decoder and to be honest i think CUVID is totally worthless these days. and the reddish would be a bug do you have a screen with OSD ? |

I don't recall having this problem with the GPU throttling a few months back. Quote:

Is there much of a difference between native and copy-back? Quote:

One final question. Is there a list of what 'trade quality for performance' options are safe to check that have little to no impact on the actual quality? Last edited by SecurityBunny; 5th July 2015 at 12:20. |

If you don't get any dropped frames, I don't see how throttling would be an issue. I get almost 32ms render times with powersaving and the playback is rock solid with 24fps videos, smoothmotion enabled. If you're using LAVFilters (also MPC-HC's built-in codecs), the decoder falls back to software for formats that your hardware can't decode, that includes 10bit videos on almost all GPUs. |

software is still the best way and most save way to decode videos it simply has better error handling. hybrid h265 decoding looks like a bad joke. i wouldn't use it. Quote:
the performance impact from copyback on nvidia system is totally meaningless copyback is just more flexible. |

Please post screenshots that show where/why you like NEDI better than super-xbr. Thanks. Quote:

FWIW, you could simply try using the default settings and check if they work alright. If they do, you can play with the settings (e.g. image upscaling or doubling) and check if your GPU can handle them and if you can see a difference or not. Quote:
OS? GPU? Quote:

Possible. I had implemented a few smaller performance improvements. And "high" deband got slower, see above. The performance improvements were really small, though, nothing dramatic (other than super-xbr and FineSharp). |
