Smooth motion mode with present several frames in advance doesn't seems to work consistently for me. Sometimes it keeps flickering between the current and past frames, it happens even when video is paused. The OSD also flickers.
Maybe it's the same problem reported when seeking, but for me it also happens when starting playback on fullscreen exclusive mode or switching from overlay to full screen. It seems to get better after a while, but I still get some random flickering. But yeah, it looks very good when it is working. Thanks madshi! Edit: Disabling "Use separated device for presentation" seems to fix it. Edit2: But it does seem to cause random framedrops =/ Last edited by shimaflarex; 21st February 2013 at 19:48. |

For those of you who can't change settings:
Please do *not* change the madVR folder permissions. Well, of course you can do that, and it will "fix" the problem, but it's not really the intended solution. I've not had the time yet to check whether I can reproduce the problem, but just in case: Please check "HKEY_CURRENT_USER\Software\madshi\madVR\Settings". The settings should be saved there even if madVR can't save "settings.bin" into the madVR folder. So I'm really confused why changing the settings doesn't work. Writing to the registry to HKEY_CURRENT_USER should always work, even with limited access right accounts! So please check if that registry key and value exists. Just as an explanation: Win7 and Win8 have a "VirtualStore" folder where they automatically store files if applications try to create a file in a folder they don't have write access to. So basically the madVR "settings.bin" file was written to the VirtualStore by the OS whenever madVR tried to create it in the madVR folder. This was not intended by me, so v0.86.0 now checks whether it can write to its own folder before trying to create "settings.bin". As a result the file is never stored into the VirtualStore, anymore. If madVR can't write to its own folder, "settings.bin" is not written at all. I thought this shouldn't harm because the settings are always also written to the registry - and that should always work. |

(Standard) LastSettingsKey Settings (shouldnīt this be a subkey? itīs a binary value with "0 0 0 0") ShowOsd ShowOsd_ So it seems there is something definitely going wrong if madVR doesnīt correctly write the settings there. Just FYI, I have full access rights to that folder! EDIT: It looks like madVR doesnīt create a Settings subkey but instead it creates a Settings binary value (see above) and thus madVR cannot store and read-back any values. Should be easy to fix for you! Last edited by iSunrise; 21st February 2013 at 20:20. |

To summarize, it seems I must have the use a separate device for presentation enabled to stop the dropping of a vast amount of frames, and then turning the AR filter off even further reduces the amount of frames dropped to a very very little amount. |

1) madVR listens to the upstream filter, ie ffdshow outputting 48hz for example? AND 2) madVR smooth set to "only if there would be motion judder without it..." should help with the slight differences between refresh rate and output rate even if its tiny like 0.06~hz difference? Thanks again. |

The image is somewhat smoother, but still judders, and has noticeable ghosting from the frame blending. It reminds me of the old NTSC > PAL transfers we used to get back in the 90s, but not quite as bad. I was checking with the Casino Royale Blu-ray, as that is my go-to disc for testing anything, as it includes scenes for just about anything you need to evaluate on a display/video processing. As I said though, maybe I am just really sensitive to it, or maybe it depends on how good the motion handling of your display is. If your display is already blurring everything with motion, maybe you won't notice the blended frames. A quick example: I think I prefer the judder to less judder plus ghosting. |

When my ST50 receives a 24p signal and my ST50 converts 24p to 60Hz, motion is smooth, but bright panning objects cause a flicker effect (easy way to see it is on scrolling end credits on a black background). Before the FRC option, this is what I used and I lived with the flickering artifacts. It was either that or output 60Hz and have my HTPC convert 24p to 60Hz, but this wasn't as smooth... until now.

Sorry if this has been asked already, but why does smooth motion conversion not work if display is at 60Hz and video has 29.97 or 59.94fps?
But MANY thanks for that new feature, it's really kind of salvation. Will test if I still experience my frame drop issue with 60fps videos and provide logs if true. Edit: Issue still exists, here is the debug log: http://www.mediafire.com/?ikqkbswscavjjay Last edited by aufkrawall; 21st February 2013 at 20:50. |

"only if there would be motion judder without it" should cover it imho. |

I use my HTPC for both videos and live tv through WMC. By default, the video card is outputting 24Hz. When I switch to WMC or when I play 60p content, accordingly, the output changes to 60Hz but it causes a blackout for couple of seconds while my AVR and TV resyncs. Kinda annoying. If I can stay at 60Hz output and still get judderless playback of 24p content, then I'm very happy. |

Would it be possible to add an option to temporarily disable FRC during seek as well as window->fullscreen, and delay re-enabling by a couple seconds to allow the render queue and vsync readings to stabilize (preferably independent from the existing delay playback options). Something like this seems like it's needed to avoid the temporary FRC instability and severe blurring artifacts in these cases.

If I move the settings.bin file out of the madVR folder, the behaviour is the same (won't save settings in the registry, or in settings.bin) |

madshi, nothing new to 0.86.0 but for me, even with delay playback until render queue is full checked, I usually get 1-2 frame drops on playback start, or if I have mpc set to repeat a sequence, after the sequence restarts, I can see the queues drop to 0 and I again will get 1-2 drops. Just thought I would mention it as I had a clip on repeat this evening testing something, and noticed lots and lots of frame drops in the stats, all coming from the each start of the sequence. I'm not sure if madVR waits for all queues to fill up before starting playback or just some?

Madshi, FRC's overhead is enough to make it detrimental on low-end cards (nvidia gt520 for example), is it possible to make FRC smart enough to auto-disable itself (even when enabled in the settings) if it detects GPU loads of 99%?
As you are probably aware, with FRC enabled at 100% GPU load frames appear out of order. Seeking might also trigger the out of order frame glitch, I'm not sure if it requires 100% GPU load to trigger. I know you can disable FRC, but there are cases where it's beneficial when automatic, for example: When you only play video, you GPU can handle the load, but if someone also uses a GPU accelerated browser on the second monitor at the same time, out of order frames appear constantly. |

I guess this might not be a madVR issue, but let me describe my issue please
I use K-lite Codec Pack for my multimedia needs. I have the latest version installed (9.7.5), and it comes with MPC-HC v1.6.6.6517, LAV Filters v0.55.2-16-gd6e6c1f and madVR v0.85.8 I use the LAV decoder filter for almost all of my video streams, and madVR as the video renderer. I have an nVidia GTX 670 with the latest WHQL drivers (v314.07), and Win7 x64. When I playbak a DVD using this decoder-renderer combination, no subtitles or subtitle overlays (menu highlights, etc) are displayed. But when I use MPC-HC internal MPEG2 decoder and keep using madVR as the renderer, the subtitles and overlays are displayed just fine. Now here's my doubt - is this a LAV issue, such as: it doesn't feed the subtitle stream correctly to the madVR renderer; or is it a madVR issue, such as: madVR isn't compatible yet with the way LAV handles subtitle streams? Thank you all for your attention, and have a great day, Brotoles |

As madshi already commented on before, screenshots will always look rather bad with blending, you need to compare and judge from moving images, and not from individual screenshots, so these serve no real purpose, but spread FUD, imho.
