I've got an issue with madvr on my new laptop (i5-4210, HD4400 or GTX850M, 8GB RAM):
When watching, I get frame drops after a minute or so. The backbuffer queue (all other queues are full!) is suddenly empty and causing dropped frames till i restart the player for another minute of flawless playback. I tried every option in madVR there is. Using either the integrated HD4400 GPU or the dedicated GTX850M doesnt seem to make a difference either. Exclusive fullscreen mode doesnt change anything either. Overall resource usage is very low while watching and with frames taking merely up to 10ms to render, i doubt raw power is the issue... HELP! |

It sounds like something is going into a low power mode? Check all your advanced power management options or try a "High Power" preset for testing. Try renaming the video player's exe? I don't think this is really a madVR issue, maybe open a new thread so we can discuss possibilities without clogging up this thread with general (video playback) PC support. Maybe link to it from here?

In addition to what Stereodude said; it isn't based off of your screen's refresh rate but the frame rate of the content you want to watch. Also madVR reports the rendering times you need to be below as "movie frame interval" in its OSD.

My guess is that something has disabled NNEDI3 in madVR/MPC (or whatever you may be using in place of MPC...like Potplayer, etc). Have you changed anything in madVR settings recently (like setting image upscaling to DXVA2)?

USA NTSC and ATSC use this weird 1.001 factor, which is why for video playback it's usually better to use 24/1.001 instead of 24, and 60/1.001 instead of 60. Quote:

Indeed it is! And although I don't use ffdshow myself, I wonder if it makes sense to select profile rules based on the upstream filter, or at least based on whether or not the upstream filter is ffdshow, since madVR can obviously detect that

madshi, I've discovered that my iGPU -> 750M problem is resolved when I select "System Default", "VMR 7 (Renderless)", or "Overlay Video Renderer" with "High-performance NVIDIA processor" selected for a renamed mpc-hc.
Strangely, I had only tried EVR and VMR 9 (Renderless) other than madVR and both of the others also gave the same black screen result as madVR. Should I open a bug report for this on the tracker and/or would you need me to provide more information? Thanks. |

Furthermore, when madVR or any other unsupported renderer (EVR/VMR9) is selected then no activity is shown for the 750M in GPU-Z. While the other mentioned renderers utilize the 750M. |

don't know if it's a bug or something that I missed, I'm using version 0.87.10. I wanted to play my video at its native 24fps, but turning deinterlacing off in madvr's setting doesn't do anything, the video still plays at 60fps.

madVR 0.87.4 + MPCHC (Windows 7 SP1 64-bit)
Chroma upscaling: NNEDI3 (32 neurons) Image upscaling: Jinc (3 taps) + anti-ringing filter Smooth motion: enabled Trade quality for performance: all unticked except "use random dithering instead of OpenCL error diffusion" Exclusive mode: enabled AMD R9 280 3GB GPU (940 MHz / 1250 MHz) with Catalyst 13.12 drivers. I'm playing 1080p24 10-bit videos and rendering times hover around ~ 22 ms with GPU usage ~ 50% (~ 70ms with error diffusion and ~90% GPU usage). It is normal that I can't use error diffusion with this GPU? There is tons of dropped frames. Rendering times are correct for this GPU?

I thought it was latest. Now I'm using 0.87.10 version.
0.87.4 I'm playing 1080p24 10-bit videos and rendering times hover around ~ 22 ms with GPU usage ~ 50% (~ 70ms with error diffusion and ~90% GPU usage). 0.87.10 I'm playing 1080p24 10-bit videos and rendering times hover around ~ 19 ms with GPU usage ~ 43% (~ 20ms with error diffusion and ~47% GPU usage). Well, I guess that noticeable difference with error diffusion Thanks for correcting this simple mistake

I am currently experimenting with my Panasonic ST60 plasma and MadVR, contrast ratio is superb (above 10,000:1), and colors are perfect (sub 2 dE with built in CMS).
First, with this particular model the madLevelsTweaker does nothing, but on my other displays it has effect; It appears the the GPU outputs 0-255 no matter what (like PC mode) when it detects this TV, In RGB or YCbCr444 modes (nVidia card). I also use the "Pixel Direct" to get 4:4:4 Chroma. To get a band-less picture I have to use the RGB Limited setting on the TV, and output 16-235 from madVR, this clips the OS shades but it does't matter for me. When using the RGB Full setting & 0-255 with madVR, the TV creates minor banding like its compressing the incoming 0-255 to 16-235 then stretches back to 0-255. Its' definitely not MadVR or Nvidia that creates the banding, it appears that the TV's processor only accepts 16-235 steps for bandless picture. All in all, I preserve BTB and WTW using the RGB Limited on the TV & 16-235 with MadVR, and without any banding. In effect madVR use one less dithering step because the image does not need to be stretch to 0-255, it stays at the native 16-235. Bottom line is: 0-255 is not always best; it depends on the display device. I use the Greyscale Ramp from the AVS709HD disc, and engage the "Reduce Banding Artifacts" in madVR for maximum smoothness, then I select the setting on the TV that looks smoothest/bandless. I suggest you do the same, to know what's the native range the TV processor expects at the input; it may accept 0-255 and show all shades perfectly but create banding as a side effect. One question remains; Can madTPG use 16-235, or is it locked to 0-255?
