Does madVR v0.85.1 behave differently on your PC? You do not have that 0.5 seconds of transparent window with v0.85.1? Quote:

And colors are alright? FWIW, this way you only get 8bit YCbCr to RGB conversion with the current Intel drivers, unfortunately. I hope this will be fixed with a future Intel driver version. And yes, chroma upsampling is done by Intel/DXVA2 in this configuration, too. Quote:

Not sure if thats a viable alternatve for madVR. Deinterlacing stays the same, but it essentially "drops" half of the frames to reduce the load on madVRs processing.

Hi Madshi
In MPC-HC, I can rotate an image by pressing Alt + Num 1, when using EVR-CP. When I use madVR, the key combination doesn't work. It seems madVR does not allow image rotation. Could you please implement that functionality too? |

The "desired display gamma value" is for setting up your display. You should in theory do that once and then leave the setting alone. The "source brightness" is meant to allow you to improve badly encoded movies. E.g. if one specific movie was encoded too brightly, just increase the "source brightness". madVR will automatically reset the "source brightness" changes you do when you load the next video, so you don't have to remember to reset the controls manually after the movie has finished playing. |

I'm interested to know what kind of hardware can't handle proper deinterlacing to 50p/60p (besides broken Arrandale of course ). A low-end nVidia GT 430 can handle it perfectly well. That'd have to be some ancient Radeon....either that or he's chosen algorithms too demanding for his GPU, in which case it'd surely be better to choose a less demanding algorithm than lose half of the temporal resolution of the image.

BTW, I've just been informed that the new version of PotP that will support PS scripts with mVR hasn't been planned for release yet and that we shouldn't hold our breath for it.....sometimes they release new versions on a daily basis, but when it really matters it might take them forever.....c'est la vie I guess =/
I never keep a keyboard within hands reach, so that wouldn't help...I guess I'll try to make a few PS scripts presets for levels conversions then. Also, the OSD doesn't seem to tell about the custom levels current state so playing around with levels blindly doesn't sound too good to me Good point, and if I keep the .ini file of PotP read-only I can play around with its saturation setting....too bad increments are 1% at a time.

Turn it on and still makes the GPU to send out 1920x1080i25/i30, this does not hurt the PQ (especially vertical resolution to me). For each frame, the deinterlaced field is actually never sent to TV. About this I remembered long time ago when my HTPC was XP + 8800GTS, it worked fine. These MPEG2 HDTV contents can be sent to VMR9 with weaving option (no deinterlace) at 100% zooming case when the output signal is 1920x1080i25/i30. Of course the field-mode-scaling on Chroma components must be used to make a YUV/RGB 4:4:4 field image. Just remembered such kinds of analysis were actually implemented on a product's deinterlacing engine designed by me long time ago. At that time, it needs to handle various NTSC / PAL / SDTV / HDTV input signal devices for interlaced contents. So a source interlaced video frame may not be actually deinterlaced on interlaced CRT/PDP. If video frame is deinterlaced and progressive signal is sent to such TV, the PQ is actually worse. But there are many combinations which need to be considered including source field order, output mode, scaling factor, pausing state, trick play, etc... Quote:

but i think the hd 4000 is a bad reference most people who get a cpu with that card get an extra gpu too. at least thous who watch videos on it the rest will use the cpu for cpu heavy programs. a hd 2000/hd 3000 or a4 apu gpu is maybe a better reference. and how about an audio renderer which works hand in hand with madvr to get rig of the frame drop repeat problem by resampling the audio by upsampling the audio to the max the audiocard supports like 48032 to 96000 so madvr runs 100% smooth without reclock and out of the box. |

You could add a very small wizard that simply asks what the user's GPU is and then set recommended scalars based on that. Might be easier to auto-detect though.

I will revert to the stable Catalyst later, since I can't remember having this problem with 0.85.1 before, and report back. (I should've done this from the beginning. Updating driver and madVR at the same time is obviously a bad idea for testing.) Maybe I will also create a seeking sample to better test seeking in the future, unless something like this already exists. Last edited by sneaker_ger; 5th December 2012 at 15:15. |

BTW going back to the BenQ W1070, these two youtube videos look pretty outstanding and rather enticing:

HD2000 is a useless reference, because it only exists on desktops without an external GPU. Not sure if HD2500 is more popular in HTPCs. |

i have tried this with dvds, xvid, and h264, same result. i'm curious what the issue is there, but the videos are getting deinterlaced using cuvid, so not a huge issue. |

the use of the microsoft decoder, dxva in general, or dxva scaling? |

DXVA scaling on Intel results in 8-bit RGB, AMD and NVIDIA output high bitdepth RGB.
