Limited and full are independent of chroma sampling. However, you cannot have chroma sampling and be RGB so your TV must be converting to YCbCr. Weather it converts to limited or full YCbCr will be harder to check.

Does exist any utility which can show percent of VideoMemory bandwidth loading on AMD's (particularly, on my HD5450)? I know such utility exists for Nvidia cards definitely, but what about AMD? GPU-Z does not show that parameter for AMD cards...

Hi, i just bought an nvidia gt 750 ti alongside with a smartv 1080p and im having several presentation glitches when i play 1080p movie at 1080p resolution, while i dont see any glitche at all, madvr ctrl j shows many...
The problem dont seem to happen while playing 720p movies upscaled to 1080p wit jinc 3 ar on chroma and luma. Only when i play 1080p movies (which dont need any upscale or downscale) the glitches appear. I use Full screen exclusive mode... Guess if the gpu dont do upscale/downscale, it wont be used and the fullscreen exclusive mode needs the gpu to do something??? TIA |

@xabregas The 750 Ti should be find for 1080p at 1920x1080 with Jinc3 AR for chroma scaling. Have you changed the dithering options or smooth motion? How about using Bicubic 75+AR for chroma scaling? Also try with Full screen exclusive disabled and Windowed Overlay enabled. Which motherboard do you have, madVR likes bandwidth so if you are on something very old there might be an issue there. |

It shouldn't change anything. However even if it did - it would only harm quality, since using DXVA-things drops precision to 8 bit, which leads to banding. I would recommend never using them, unless you're using intel GPU and very limited with resourses. Last edited by vivan; 7th July 2014 at 05:38. |

Hello,
Not sure if this is reported: madVR doesn't work (it only renders first frame and died [not crashing]) for me if I set it to use external graphic instead of integrated graphic in optimus setup. - madVR 0.82.10 - Intel i7-4710HQ (mobile processor) - nVidia GTX850M It work fine if I set it to use integrated graphics only, but that would be a waste. I am on latest nVidia driver (337.88). I used to use Optimus before in i7-2630QM+GT550M and it works fine running in external CPU on same driver/madVR version.

I have just upgraded from 0.8.6.11 to the newest version and am getting GPU driver chrashes.
I use MadVR primarily because I can watch movies and fold at the same time, thanks to the FSE mode. Even though F@H consumes 95-98% of my 7870 I could use Jinc3 AR AND SM on 0.8.6.11 while folding simultaneously. But not so with the newest version: even lowly bicubic causes driver restarts. I do not use image doubling nor error diffusion. Since F@H uses OpenCL, I suspect that it could be fighting with madVR for use of OpenCL resources somehow. So, basically, my guestion is: for which madVR functions is OpenCL used? Apart from NNEDI, ofcourse. Thanks for your answers. |

@kopija:
NNEDI3,ERROR DIFFUSION and under general "use OpenCL to process DXVA NV12 surfaces" the newer version got some tweaks for optimus system could be a problem with that. but is works totally fine with out F@H (what ever that is), right? else: http://bugs.madshi.net/my_view_page.php feel free to add a entry. Madshi is currently working on other things. so it better to add it there to make sure he will look at it later on. edit: @innocenat please try a newer version of MadVR 82.10 is ancient and report back.

My results with R9 290X and various observations
First I'd like to thank madshi and the community for such an excellent product
I have a watercooled R9 290X that's pretty consistent with its clocks (no overclock yet, stable at 1000MHz) and even this beast of a card can't handle everything without the occasional frame drop. Specs Windows 8.1 (Update 1) 64-bit (Pro w/ WMC) Haswell Xeon 3.5GHz (w/ HT) 16GB DDR3 RAM AMD Radeon R9 290X 4GB GDDR5 AMD Driver version: 14.16 (no difference with 14.14) madVR version: 0.87.10 Software Used: MPC-HC "Lite" (*), MPC-BE (*), LAV Filters 0.62.0, ReClock 1.8.8.4 * - All internal filters disabled. madVR & ReClock Configuration Code:
ReClock - WASAPI Exclusive - Assume source is 30 FPS or Refresh Rate / 2 - Pre-Buffer: 100ms - Quality: Best Sinc Interpolation - Added MPC-BE to ReClock's "load always" since it's not added by default. (all other defaults) madVR 0.87.10 Configuration (If not mentioned, option is disabled.) Deinterlacing: - Automatically activate deinterlacing when needed -- if in doubt, deactive deinterlacing - Only look at pixels in the frame center. artifact removal: - reduce banding artifacts -- default debanding strength: low -- strength during fade in/out: medium Scaling Algorithms (All) -- image downscaling: Catmull-Rom w/ Anti-Ringing Filter + Scale in Linear Light Scaling Algorithms: <=360p -- image upscaling: Jinc, 3 taps w/ Anti-Ringing Filter -- chroma upscaling: NNEDI3, 256 neurons -- image doubling: Always Double Luma, 64 neurons + Always Double Chroma, 16 neurons (*) Scaling Algorithms: 360p<=480p -- image upscaling: Jinc, 3 taps w/ Anti-Ringing Filter -- chroma upscaling: NNEDI3, 128 neurons -- image doubling: Always Double Luma, 32 neurons + Always Double Chroma, 16 neurons (*) Scaling Algorithms: 480p<=720p -- image upscaling: Jinc, 3 taps w/ Anti-Ringing Filter -- chroma upscaling: NNEDI3, 32 neurons -- image doubling: Always Double Luma, 16 neurons + Always Double Chroma, 16 neurons (*) Scaling Algorithms: 720p<=1080p -- image upscaling: DXVA2 -- chroma upscaling: NNEDI3, 16 neurons -- image doubling: (None) * Note: AMD interop hack doesn't seem to make a difference for my tests. General Settings - Delay playback start until render queue is full + delay playback start after seeking, too. - Use OpenCL to process DXVA NV12 surfaces. - Use separate device for DXVA processing. - CPU/GPU queue size: 24 windowed mode settings: - 16 frames in advance - (rest are set to defaults) trade quality for performance: ALL disabled Smooth Motion - Enable smooth motion frame rate conversion -- ...or if the display refresh rate is an exact multiple of the movie frame rate. Dithering (< 720p): Ordered Dithering Dithering (>= 720p): Error Diffusion #2 Monitor HP LP2465 (1920x1200 S-PVA panel) - Properties: PC Levels (0-255), 8-bit (or higher) - Calibration: Disabled + Disable GPU gamma ramps. - Display Modes: (None) - Color & Gamma: 0/disabled - Enable AMD Video Quality features in selected video player applications: UNCHECKED (disabled) - Enforce Smooth Video Playback: UNCHECKED (disabled) 720p Hi10P Average Stats: - Rendering (madVR): 28ms - Interop (madVR): 10ms - Present (madVR): 0.10ms - GPU Utilization (HWiNFO): 58% (*) - D3D Usage (HWiNFO): 23% (*) - Time Spent with very high (>90%) GPU Usage: 28% (*) Note: No dropped frames over this report. (*) I have a super-fancy spreadsheet I made to calculate all of this. I have tried a large number of different settings from suggestions online and in this thread, and so far these have shown to be the best -- however there are plenty of different source material (I'm mostly testing on anime) that trips it up. Here's some especially weird stuff: * My settings don't seem to like ReClock set to 24 FPS (for ~24 FPS source), causing more to significantly more dropped frames. I have two monitors connected in an "Extended" desktop: 24" 1200p S-PVA workstation monitor and a crappy 32" 1080p TN HDTV. Both can support 24Hz natively, especially the 1080p, though I must use CRU to add 24Hz for the 1200p, however, even the 1080p set to 24Hz causes significantly more dropped frames (same with 48Hz). Just to check if it was the case of using Windowed and two monitors running different resolutions, I set both monitors to 1080p@24 and the same problem occurred. But I'm guessing the reason it's totally unplayable if Monitor #2 (1080p, Secondary) is set to 1080p@24 and Monitor #1 (1200p, Focus) is still set to 1200@60 is how Windows handles refresh rate differences like that. * Full-Screen Exclusive Mode gives more to significantly more dropped frames for me, and can introduce artifact errors. Again, note that I can't get EDID for Monitor #2 (1080p), and it's using some generic PnP driver, and Monitor #1 is a 1200p workstation monitor that doesn't support 24Hz (or 48Hz) without hackery. Hence I've settled on ReClock with 30 FPS or Refresh Rate / 2, which requires Smooth Motion enabled or else I'll get significant judder on anime pan & scan. Note on Pan & Scan in Anime: I've found certain sources -- say, HorribleSubs -- often have low bitrate sources that will have problems on pan&scan no matter what you do; only outright frame-doubling really helps here (SVP, CUVID, etc.). On Windows Power Profile: I'd like to stress that you should be using "High Performance" if you're having any sort of trouble, NOT just changing settings under "Balanced". Process Lasso is an example of a program that will set the power profile for you based on what programs are running. Last edited by generalmx; 8th July 2014 at 04:40. Reason: Formatting. |

Reclock flawed at 24hz - madVR workaround
Quote:
My work around was to delete the 1080p24 and 1080p23 display modes from the list of supported display modes in my madVR settings. With it set as 1080p60, 1080p59, 1080p30, 1080p29 Reclock goes to the next closest thing (30hz). I proposed a change to reclock setting options based on another type of 24hz flawed playback experience (detailed at the linked page), but nothing ever became of it. https://forum.slysoft.com/showthread.php?60908-Proposal-for-future-Reclock-setting%28s%29&

Unfortunately I haven't yet found a combination of madVR settings that prevents dropped frames in this situation, though I know it's my madVR settings as using a different renderer (with or without ReClock) works fine...which is a shame, since it's these anime that looks absolutely brilliant with NNEDI3, so I've just been rewinding when it happens (it's not consistent either). |

With "don't rerender frames ..." trade quality for performance option disabled, when madvr detects a fade in/out it drops frames and rerenders them using other debanding setting. If this works as intended you don't even notice it, but if you have maxed out settings and one fade in/out after another in the video you rerender frames almost constantly with different settings. That's why some quality trade-offs are enabled by default In you previous post you have mentioned judder with some sources, are you sure it's not in the source? If your encode or deinterlacing goes wrong you will get duplicate frames, which means judder during pan scenes. Easiest to check by frame-stepping through the panning scene. |

@ generalmx:
For ReClock settings, I have found that the best way to work with madVR is to have every single option un-checked on both the advanced settings and the audio settings. Also is there a reason you are using WASAPI? DirectSound is all you really need to use, unless there is a specific reason. Have you tried using 13.12 AMD drivers? Any of the newer drivers cause performance drops with my 270x... maybe something you should look into as well QB
