v0.86.11 works with all settings, memory usage is 1660 MB in FSE (LL on) and 1630 MB in FSW (LL on).
Same settings as above, defaults plus: LL downscaling 24 GPU buffers (28 CPU) Sorry I edited my original post with more details. Edit: GPU buffers at 10, back buffers at 8 FSW, 1175 MB (LL off), 1325 MB (LL on) Last edited by Asmodian; 27th January 2014 at 01:41. |

0.87 added a new debanding filter and fixed a bug leading to frame drops. Most of the problems 0.87 introduced should be fixed in 0.87.3, and the OpenCL options won't affect you unless you enable them. Last edited by Ver Greeneyes; 27th January 2014 at 01:52. |

I have a question about image doubling(which also applies to the scaling factor requirement). Does doubling mean doubling the total amount of pixels, or doubling both the height and width (quadrupling the total pixels)?

@Ver Greeneyes
Here are the results of the discussion as understood by Niyawa: As I understand their preferences 6233638 prefers less ringing to a bit sharper which is why they prefer Mitchell-Netravali to Bicubic 75. This is of course perfectly reasonable. I hope I am correct as to your reasoning, 6233638. Quote:
@madshi Another note, using v0.87.3 with my normal settings (everything on ) watching 1080p on 1440p I see 2624 MB of video ram used when in FSW. Last edited by Asmodian; 27th January 2014 at 04:51. |

Hardware for deep color
Hello!
For about one month I'm trying to send video, from my HTPC, with more than 8 bits per color to my projector. I have tried Nvidia, Ati and Intel graphics (basic models) but without success. I know my projector is 12 bits capable because I test it with a BD player and works. I think the problem is the graphics card or the drivers. My SO is Windows 8 and my favorite player is MPCHC with Madvr, of course. Can you tell me some cards, with moderate price, to get 10 o more bits? Very thanks. |

Is the problem with dragging the screen to another monitor fixed? It would stop playback and you'd have to open the file again with the player on the second screen for it to play, or it would just stay stopped no matter matter. Pausing and Playing did nothing.

I think the performance of error diffusion is quite poor on my computer (Radeon HD 6850 with Catalyst 13.12). Here is a little comparison:
720p50 to 1080p50:
It seems that also Vyral has these performance issues with 6850: Quote:

A bit of background... I mostly use MPC-HC, MadVR, LAV, FFDshow (raw), Reclock, AviSynth and AC3 Filter. Viewing/testing consists of analysis of video sample quality utilizing AviSynth(MT) based utilities - I don't watch movies or TV but I love to tweak :-). These samples often exceed 1080P (1920*1080/29.976 progressive) - going up to 4096*2304 DCI-P3. For the past few weeks I've focused on AviSynth OpenCL variants - notably nnedi3ocl. In my estimation the current MadVR release (87.3) performs similar (within 15% or so) to what I have seen via AviSynth. My take on this particular usage of OpenCL is that it facilitates load balancing across the GPU/CPU while nnedi3 can certainly improve up-scaling quality - you can work wonders with low-rez porn clips :-). It isn't a free lunch. And it's very heavily GPU dependent - resolution is everything. Up-scaling 854*480P to 1080P vis Interframe2 and/or SVP is about the practical limit on my rig before encountering occasional dropped frames. Note that I simultaneously employ video smoothing (frame interpolation) utilizing frame doubling, sharping and the like as needed. YMMV :-) I offer-up a sincere thanks to all involved. And Madshi..you are the bomb! :-) Last edited by MistahBonzai; 27th January 2014 at 06:47. Reason: missing HTML tag. |

Using v0.87.3 my system works if I use the defaults with 8 back buffers in FSW, FSE off is the only other thing I have changed. Everything looks great in all these tests. 4K->1440p 30p v0.87.3 queues 16/8/3 LL On 1683 MB LL Off 1525 MB queues 16/8/8 LL On 1787 MB LL Off 1617 MB v0.87.3 queues 16/9/8 LL On 1823 MB LL Off 1654 MB 16/10/3 (worked this time? ) LL On 1779 MB LL Off 1609 MB V0.86.11 queues 16/8/3 LL On 1639 MB LL Off 1511 MB queues 16/8/8 LL On 1704 MB LL Off 1537 MB I the process of making this list I found something very odd. Queues 13/13/8 works (good picture) but 13/12/8 gives black screen. 14/13/8 and 15/13/8 give black but 16/13/8 gives a good picture. This seems to be true with LL on or off, 24/22/8 LL Off (2295 MB) works but 23/22/8 doesn't, 23/20/8 does. Very odd; and these exact queue sizes seem to change. Sorry for the lack of good data. I have tried restarting the player (Zoom Player) between setting the queues as well as restarting the computer but something may be wrong with my testing methodology for this. Please let me know if there is anything I can do to help. Last edited by Asmodian; 27th January 2014 at 06:29. |

For the madVR 0.87.x debanding with angle-detection along with Jinc3AR mode, it seems to make the X-RealityPRO XCA7 engine's super-resolution processing more stable on quick motion object's edges. |

Madshi,
Can you please add a "Stop cadence search", "Lock cadence" keyboard shortcut, or "Stop search once 3:2 found" option in Proccessing->Deinterlaced->Film Mode. The reason is even in a known 24p telecined to 29.97i content ivtc still breaks cadences sometimes. I don't know if it is appropriate to compare to other software, but I will for reference. I own PowerDVD 13, in which Film Mode is completely automatic, when it detects soft telecined 29.97i it will switch to 24p and stay there. For PAL DVD's it just stays at equivalent Video Mode. Maybe its done with "Flags" or what (I'm not well read about that matter), but it just works, no cadence breaks and no resulting micro stutter. Thanks.

Hi, 1) My app is not free, so can I ask for a free license or do I have to pay license fee ? 2) Still I can not make it to work : Here the code I use. I can see the madvr window inside my CView pane, and something that is moving (like a video playback) with flickering. Code:
//Initialize madVR hr = m_pMadVR->QueryInterface(IID_IVideoWindow, (void **)&m_pVidWin); if (SUCCEEDED(hr)) { m_pVidWin->put_Owner((OAHWND)m_hMediaWindow); m_pVidWin->put_WindowStyle(WS_CHILD | WS_CLIPSIBLINGS); hr = m_pMadVR->QueryInterface(IID_IBasicVideo, (void **)&m_pBasicVideo); if (FAILED(hr)) { ReportError(_T("Failed to initialize IBasicVideo (madVR)."),hr); AMLOGINFO(_T("Failed to initialize IBasicVideo (madVR). errorcode=%s."),GetErrorCode(hr) ); return FALSE; } } else { ReportError(_T("Failed to initialize IVideoWindow (madVR)."),hr); AMLOGINFO(_T("Failed to initialize IVideoWindow (madVR). errorcode=%s."),GetErrorCode(hr) ); return FALSE; } //At my resize method BOOL CGraph::Resize() { ................ if (m_RendererType == MADVR_RENDERER) { GetClientRect(m_hMediaWindow, &wndRect); m_pBasicVideo->GetVideoSize(&size.cx, &size.cy); m_pBasicVideo->SetDefaultSourcePosition(); m_pBasicVideo->SetDestinationPosition(0, 0, wndRect.right, wndRect.bottom); m_pVidWin->SetWindowPosition(0, 0, wndRect.right, wndRect.bottom); } ........... } |

Thanks for 0.87.3 madshi, working great on my system. Letīs hope you can get the OpenCL stuff to work on NV, as I really want to test the new NNEDI3 for instance. Still having a lot (and I mean A LOT) of lower resolution movies (DVD) and videos where this could make a lot of sense.
So C++ isnīt a "proper" language in your world then? Ok, I donīt think we need to discuss this further. |

I did.
The video has multi-cadence parts so madvr keeps switching between them. I just want to stop cadence searching, and freeze on a certain cadence. EDIT: madshi, Have you ever thought about adding a smart DeNoise & Sharpen algorithms? I use the ffdshow "Blur & NR" -> denoise3d, for removing compression noise/grain and artifacts. A little goes a long way (no need for strong settings), almost looks like its twice the bitrate with no apparent PQ/Sharpness loss. There is a problem with ffdshow: its 8-bit, and any change destroys madvr 16-bit workflow. With Dithering + DeBanding we currently have in MadVR, DeNoise from ffdshow, and MPC-LumaSharpen (from SuperFX, the best one yet) sharpening, I get a better picture from a full 50Gb blu-ray than it can ever have. Almost Digital Cinema quality in terms of noise and PQ with these together (DCI is almost 300-500 Gb for a single movie). Do you have plans to further add quality filters into MadVR like you did with NNEDI & Debanding?
