View Full Version : I have some issues using MPC-HC with MadVR

I have an HP 15 laptop which has a MX 570A graphics card. I used the settings which are mentioned in https://www.reddit.com/user/Expensive-Post5578/comments/17evwa5/best_madvr_settings_for_general_usage_rtx_4090/. Also, I forced MPC-HC to use the MX 570A graphics card instead of the Intel graphics card.

I have x265 movies. Most of the movies are smooth when I play them. A few movies are choppy\slow motion when I play them and it's like that from the beginning of the movie. Also, sometimes a movie starts playing smooth and then it becomes choppy\slow motion and if I close MPC-HC and run it again then the movie is smooth again when I play it.

Another issue is sometimes the whole screen is black when I pause the movie.

I want to ask:

1) Is the movie starting smooth and then becoming choppy\slow motion later on is because my graphics card is too weak to handle the settings that I used? If yes then which settings in MadVR do I change so my graphics card can handle playing the movie?

2) Why are some movies started playing choppy\slow motion from the beginning of the movie? Can i change some settings in MadVR to fix that?

3) How do I stop the screen from becoming black when I pause the movie?

these settings are terrible. i highly recommend you to start fresh...

this maybe fixes most of your issues already.

Please make me screenshots of all of your madVR settings.

no i'm not going to do that that sounds like work.

If the videos are 10-bit HEVC that might be why.. most hardware decoding of HEVC is 8-bit.

if you see those settings no. nvidia has 10 bit hardware decoding since day 2 there was a coupel of very old cards that could only do 8 bit hybrid the rest do 10 bit HEVY directly. and this is ampere BTW.

Hardware support does not guarantee software support. VLC for example doesn't have 10-bit HEVC decoding support.

Easy way to see what's happening.. play a problematic video, right-click while it's playing and select filters>LAV Video Decoder and look in the upper right where it says active decoder. If it says "avcodec" it's not hardware decoding.

At least tell me which settings are bad and need changing.

pretty much all adaptive sharpening 10 is just insane adding the other 2 sharpener on top of that at maximum shoudl say anythign that should be said DXVA 2 downscaling is beyond reason. the setting are so utterly insane your GPU is not going to be happy with it and most likely only working at all because you are downscaling.

there is nothing to work with here just someone that preset random stuff in the setting untill he reach the maximum...

try the low setting here: https://forum.doom9.org/showthread.php?p=1709814#post1709814

they are old settings and may need the usual bug fix changes.
don't untick all trade for quality settings there are some that are important to change like the HDR stuff that will make the GPU tank but generally they are selected for a reason.

So you mean that the settings that I am using are too heavy for my graphics card?

Also, I want to ask you why does the screen become black when I pause the movie?

i can only guess with such insane setting. maybe it is DXVA scaling. no one uses horrible setting like that. DXVA dowenscaling with nvidia is known to be the lowest of low quality for years.

i'm not going to reproduce this. this is so far from reality i really don't bother to even check. if you get similar issue with sane settings them we have something to look into but this just no i'm not doing that.

with settings like that i wouldn't be shocked if the driver crashes...
forced super sampling to 8K downscaled by 8 bit nvidia DXVA just no.

You should say whether you're using avcodec or not.

I am sorry. I don't understand what you are talking about. I have zero experience with MadVR.

I found https://www.youtube.com/watch?v=TOHzeUR1xx8 and I made some modifications to my settings based on it.

I did the following things:
1) The guy in the video said not to touch processing. I kept my artifact removal settings under processing as they are
2) https://i.imgur.com/8gZe8aQ.jpeg are the new settings for chroma upscaling under scaling algorithms
3) https://i.imgur.com/zLXNJSO.jpeg are the new settings for image downscaling under scaling algorithms
4) https://i.imgur.com/viySpKA.jpeg are the new settings for image upscaling under scaling algorithms

The rest of my settings are the same. Am I still using DXVA dowenscaling with nvidia or it's gone?

Are my settings better now or they need to be changed? If they need to be changed then please list for me all the things to change.

First I need to know what are the settings for a powerful graphics card. I will buy a gaming laptop which has RTX 4070 and I want to install MadVR on it.

After that I want to reduce the settings so the weak graphics card of my HP 15 laptop can handle it.

How do I check that?

1. reset and only use it when you need it anti ringing is expensive and can damage an totally fine image. same for deband it can damage a totally fine image. and you said not to touch it because he is not insane!
2. you have to check if your GPU is happy with that but he told you how to do that in a very basic way.
3. bit extreme but if it runs.
4. try it out. looks sane.

and does it still black screen i mean it is not supersampling anymore and trying to use DXVA downscaling...
don't forget to change your dithering to ordered. or start from fresh and follow that video. is it perfect no... and that's good so.
