Hi,
Been using madVR from the start but decided a year ago to switch to a Dune player. This still does not satisfy me so I decided to switch back to HTPC. After a clean install of my system and installing all lastest drivers, MPC-HC, ffDSHOW and madVR some first questions are here: 1. what pixel format output do I pick at the ATI CCC settings? yCbCr 4:4:4 Pixel Format yCbCr 4:2:2 Pixel Format RGB 4:4:4 Pixel Format Studio (Limited RGB) RGB 4:4:4 Pixel Format PC Standard (Full RGB) 2. the ATI CCC got some new function I see. There is 'Brighter Whites' which can be enabled/disabled. I can imagine this will be important to set this on or off. What to choose here? 3. Dynamic range can be altered in the ATI CCC settings Just leave this off? 4. PullDown detection and Smooth Video Playback in the ATI CCC. On or Off? 5. FFdshow: only check output YV12? 6. madVR. I see that madVR got decoding options! Check all and use ffmpeg software decoder? Or is ffdshow decoder still better to use? 7. What are some good algorithms settings to use? Looking for some (basic) settings that can be used for all type of movies that do not cause too much artifacts. 8. See a lot of new rendering options since the first versions of madVR. Is there a guide somewhere to find out what they do/which make quality better? Maybe more questions will come but I think this is enough for now Thanks! EDIT: And of course my setup: HTPC (w7 x64) with ATI 5450, Core2Quad Q9550 oc, 8gb DDR3 1333. JVC RS25 projector Last edited by THX-UltraII; 1st October 2011 at 12:07. |

And if you need a limited range display, you can set the display to limited range in madVR. Quote:

I have found the other algorithms (other than Lanczos and Spline) don't produce a sharp enough result for luma upscaling, but softness is fine for chroma.

How do I set madVR to Limited range and why exactly should I do that? Are those LAV filters new? Never heard from them. Where can I get them and is there a guide somewhere how to use them? |

Just run the installer, it *should* take care of everything.

What about the LAV Output Formats setting? Check only RGB? Athe RGB Output Levls? Is it best to set it on 'untouched' (as input)? |

As for the RGB output, just use full range.

In addition, both LAV and madVR support 10-bit properly, while ffdshow doesn't - it only supports 8 bit formats, so the decoder dithers the input down when playing a Hi10P file. Normally, this wouldn't be a problem, but it doesn't dither correctly either, so you'll get image artifacts. It's mainly a quality and performance issue, not an issue of crashing.

1. Use LAV Video decoder to decode and dither down to 8-bit (it does this properly unlike ffdshow) 2. Use the ffdshow *raw* video filter to host avisynth scripts That way you can use flash3kyuu in realtime. You won't have 10-bit textures but the difference will be very minimal. Just make sure you dither back down to 8-bit using proper levels in avisynth (don't let ffdshow take care of *any* dithering). Set the ffdshow video decoder to “block” and the raw video decoder (aka raw filter) as “prefer”.

Can I use MPC-HC, madVR and LAV filters for the best PQ? |

You'll need a very strong CPU to do color space conversions, gamut mapping, debanding, dithering etc. in realtime, but if you can handle it then by all means skip madVR and just output RGB32 from your avisynth chain.

Now if madvr has avisynth support my dream media setup is complete, but that's asking a bit too much I guess. |
