nothing limited to madVR. just the general. impossible to use the xy/vsfilter, some renderer can't display subtitle. nothing that should be part of this in my eyes. just basic stuff like this.

maybe this:
madVR can't accept p010 from DXVA native. i'm not even sure if there is a stable software that is trying to do this.

image up or downscaling isn't used when displaying 1920x1080 content on a 1080p display, correct? I'm asking because i've read that upscaling is used on everything, perhaps i've misunderstood that article.

Its chroma upsampling that is used always, cause 4:2:0 needs to be upsampled to 4:4:4.
1080@1080 doesn't need any image upscaling, but keep in mind that some *1080* videos are not exactly 1080 (1077 or so).

I did some minor updates and corrections and I expanded the calibration section some. yCMS deserves a mention at least.

This is good to know but I am not sure where to put it. Maybe simply as a note near the end?

What about creating the section like "known problems" or "limitations"?

this is only affecting the gtx 960 at the moment no other card can hardware decode 10 bit sources at least AFAIK.

and it was not 100% correct from me to say it can accept it. it simply shows a green/black screen when native DXVA feeding P010 in madVR.

some other limitations i know are:
madVR IVTC can detect a lot of cadences but can "only" handle a couple of them correctly.
it can handle at least 3:2, 5:5 and 8:7 from a 60i source. very rare cadences like 3:2:3:2:2 (25 fps in 30i 60 fields) 4:2:2:2 doesn't work

Quote:
madVR currently always switches to 23Hz when having forced film mode on while playing 59i content. Yeah, with some cadences 23Hz is not the optimal refresh rate. But that's not so easy to solve, especially because cadence detection can be unstable. E.g. what happens if cadence detection switches between 3:2 and between 3:2:3:2:2 all the time? Should madVR then always switch between 23Hz and 25Hz all the time, in the middle of playback? This is a problem I'll have to revisit later, but I don't consider it a "bug" right now. It's as intended, even it might not be the best (or even the correct) solution.

the decimation feature is currently not working the way it should be. see here: http://bugs.madshi.net/view.php?id=1...51e1f417cb10e6

madVR can't do frame packed 3D

and this from the madVR thread

First of all, great guide. It must have taken a lot of work to write such extensive explanations.

You've asked for suggestions, so here are mine:

Technical nuance: madVR looks for tags in the whole path, so both folder(s) and file names.
Pro Tip: put tags in folder(s) name(s) if you have a whole collection of broken rips (files), to save a lot of work (time).
You can even put tags in folders' names on different level for maximum flexibility, for example to get a monster like this:
D:\Movies\TV Rips levels=tv\Broken PAL Rips matrix=PAL\my broken rip from the 90s.mkv

What you've listed is of course correct, but you're missing a few tags and possible values.
Tags with missing values or missing altogether (all taken directly from changelog.txt included with madVR):
Quote:

* added tag "primaries=2020|DCI|709|SmpteC|EBU|sRGB|NTSC|PAL|470M|240M|170M"
* added tag "levels=PC|TV|fullrange|limited|doubleExp|tripleExp"
* added tag "blacklevel=%value%", value range [-50, +50]
* added tag "whitelevel=%value%", value range [-50, +50]
* added tag "contrast=%value%", value range [-100, +100]
* added tag "brightness=%value%", value range [-100, +100]
* added tag "saturation=%value%", value range [-100, +100]
* added tag "hue=%value%", value range [-180, +180]
* added tag "frameRate=%value%", e.g. 23.976, 24.000, 23, 24, ...
As a side note you can use either range=... or levels=... tag for the same effect.

Thanks for the guide and keep up the great work

I agree, we have gathered enough items for this section.

Good info, Thanks!
These kinds of things could take a long time to debug on your own.

Great info! Thanks a lot. Good pro tip, I hadn't thought of using them in folder names.

here is my source for the DXVA native P010 problem:
http://forum.doom9.org/showpost.php?...&postcount=305
it is a green screen. i guess this information is crucial because i can't reproduce this problem on my own. i don't have a hardware decoder for 10 bit HEVC to output p010.

and it looks like you skipped the decimation feature from madVR created for 720p60/720p50 broadcast with 24p/25p film content.
madVR IVTC can decimate progressive streams. just press control + alt + shift+ t to force it on. it has the same limitation like madVR IVTC. in the end it's the same program working.

here the part out of the change log. it is one of the newest feature.
Code:
* added support for decimating 50p/60p movies to 25p/24p

Thanks again, I had missed that decimation feature. I seem to have hit the limit for characters per post so I was unable to add the section. I may edit for reduced character count.

Other Features:
-madVR IVTC can decimate progressive streams such as 720p60/720p50 broadcast with 24p/25p content. Press control + alt + shift+ t to force it on. It has the same limitations as madVR IVTC.

edit: some minor edits for length allowed me to add the Other Features section.

Updated for madVR v0.87.15

Some big fixes. Portrait mode displays (rotated) work! Also Optimus black screen fixes.

There is a bug when picking the color matrix so BT.601 is selected for HD resolution video in some situations. Video flagged correctly is handled correctly as far as I have tested. Most likely a new build soon.

edit: fixed, up to madVR v0.87.17 now.

Updated to v0.87.21

A 64-bit build is now available.

No major changes in the options.

Hey Asmodian,

Maybe we can update the guide for v881? Thanks for the awesome work

Yes, I hope and expect the options change a lot in the near future but I will still attempt an update for v0.88.2 soon. However, it will not cover the fine tuning options for the new enhancement shaders or similar details.

Updated for madVR 0.88.4, as always please offer corrections and suggestions.

D3D11 support allowing 10-bit output and a collection of sharpeners. Another major update!

"present a frame for every VSync: when disabled madVR only presents new frames when needed, relying on D3D11 to repeat frames for each VSync."

Search the last week's pages of the madvr thread about this. He said that we should disable it for more speed if we have certain setups. I don't recall how but I'm in that group, I have an R9 290 on Windows 8.1 64.

Yes, are you suggesting I add a note that it might help performance? I don't seem to have a change in performance with it off or on.

I doubt it's going to be noticeable to most. I guess it's some kind of minor improvement of the kind of 0.1-0.2% or something. He said the option solves problems in some setups but in others it's only some latency.
