Maybe if you have a source which was encoded in a weird way, using the source contrast control could be used to make it look better. For a properly encoded movie, none of the source color controls should be used. Their only purpose is to give you some room to play with badly encoded movies... |

I don't know if that's really necessary or even useful. Chroma upsampling alone is relatively cheap. Using DXVA for only chroma upsampling would require me to follow up the DXVA processing with some added processing steps on my own, so I don't know if using DXVA for chroma upsampling would even bring any performance benefit.

Ah yes, I remember. But I don't remember having read that disabling the "use a separate device for presentation" option might help with Optimus systems. That was news to me. Or maybe I just forgot about it, don't know...

I didn't really see how you could just play around blindly with saturation, but OK some movies might look undersaturated and that'd be a quick fix...but setting up the levels conversion blindy? A real world scenario for my custom levels filename tagging is movies that went through several successive PC>TV conversions for instance, I currenty use this script in avisynth: Code:
SmoothLevels(preset="tv2pc") #SmoothLevels(input_low=30,input_high=218) #SmoothLevels(input_low=42,input_high=204) #SmoothLevels(input_low=52,input_high=192) So the real world solution for me to "fix" those movies w/o relying on 8bit avisynth processing will be to add levels conversion PS scripts using those very values. Otherwise, they could also be used via those new mVR settings you were mentioning....playing around with custom levels blindly might be possible for black level but hard to calibrate for white IMO, so at least a visible indication of where you are currently standing might help Last edited by leeperry; 8th December 2012 at 01:47. |

@madshi
i have some TS files like this↓ sample - 36 Sec.trimmed with Avidemux when seeking ,MPC-HC crash.[madVR + Lav DXVA2 native] If I use LAV Decoder in "software mode" the video plays fine. EVR CP + Lav DXVA2 native,no problem.

Hmm. Probably not worth it though - the only advantage really is probably being able to have anti-ringing on both chroma and luma, in exchange for probably a significant decrease in battery life.

madshi,
Is there a way to use MPC-HC, madVR, and LAV Filters on unix, OSX specifically? Possibly a way to port it? I don't think there's anything that can be done but thought I'd ask since a friends of mine who uses osx likes the setup with madVR, MPC-HC, and LAV Filters that I showed her. I was wondering if it might work well in a Windows 7 virtual machine as a possibility. Would madVR, MPC-HC, and LAV Filter be able to perform well/appropriately in a virtual machine? The macbook pro is from 2010 mid-level specs. i5-520M, 4GB DDR3, GeForce GT 330M w/ 256MB VRAM. Thanks! Last edited by dansrfe; 8th December 2012 at 03:19. |

Some VM software like parallels offers 3D support, but I suspect it is not going to work well with madVR. The easiest solution would definitely be dual-booting, and I would recommend Windows 8 due to its low price, and much quicker boot times.

Hello everyone-my first post here!
Id like to thank you for all the work you did to make madvr possible. I've got a few questions about it,tho: First of all,my pc is winxp 32bit,amd phenom II x2 3,1ghz,and radeon HD4870(latest drivers),and i got 4gb of ddr3 ram. Deinterlacing-activating deinterlacing on any type of content (from dvd to 1080i) makes my pc to drop half of the frames. Why is that so? Is my pc lacking resources to deinterlace PAL dvds? Also,i noticed that deinterlaced video is brighter and got somehow more vivid colors,why is that so? I'd also like to ask what exacly are delayed frames,they usually happen a lot when im watching hi10p anime (720p),but it rarely drops any frames (at end of playback you can have like 1000 or more delayed frames),if that helps,im running dell 2209wa on 76,416hz using powerstrip. Is it possible that 720p hi10p video needs more resources than full hd material that doesnt drop or delay any frames during the playback? Im using LAV decoders and splitter(im streaming audio through s/pdif) ,and Haali media splitter for mkv files (i tried to increase its buffer size to 192000,but didnt help in anything i think). Id be glad if you could answer me,also keep up good work,this is awesome renderer! edit:im using latest mpc-hc |

BTW, those numbers confuse me slightly. The formula to expand is "newValue = oldValue * 219 / 255 + 16". So if we do the math, we should end up with this: fullrange: 0 - 255 limited range: 16 - 235 double expanded: 29.74 - 217.82 triple expanded: 41.54 - 203.07 quad expanded: 51.68 - 190.40 Quote:
Make sure you don't force anti-aliasing, anisotropic filtering and that kind of 3D stuff in the GPU drivers. That might help. Quote:

here is the OSD after 5 seconds of playback with deinterlacing on. without it there would be like 0/0 dropped/delayed frames,you can imagine the stuttering! Quote:
ive been trying to force 72hz on this screen for fluid playback of hd 23,976fps materials,but it will take me some time to figure right values in powerstrip :3 (this panel is capable of such refresh rates,it doesnt drop frames) edit: i just upgraded from v0.85.1 to v0.85.2,deinterlacing still looks bright and shiny Last edited by konakona; 8th December 2012 at 14:06. |
