madVR - high quality video renderer (GPU assisted)

[tp4tissue]

Use 8bit 444, there's no reason to go down to 422 for 10bit. 444 is way more visually impactful than 10bit, and that's assuming the device actually does 10bit properly.

The only thing 10bit is visually useful for is smooth gradients, which don't come up often in movies. Whereas 444 flat out gives you better texture detail, and this is across the board.

I don't know how that device behaves for color but it shouldn't clamp saturation based on bit-depth, unless it's suppose to be kicking into an sdr/hdr mode.

The Nvidia control panel only has a choice of 8 bit or 12 bit for some reason, so I'll just use 8. Where do I choose 4:4:4 for 8 bit though?

Does anyone think madVR will work in Windows 11 ok ?

[huhn]

i know it does work.

Not strictly madVR related, but this thing happens with Kodi DSPlayer using madVR... I repost from Kodi forums, hoping that with so many video enthusiasts here my chances of a solution might increase.

I want my Kodi GUI at 60Hz. I start from my desktop at 60Hz. Kodi starts at 60Hz. When I play something it switches refresh rate correctly. I stop the video. I exit Kodi. As soon as the process is terminated (Kodi.exe, I mean), the screen switches to 50Hz.

Anything comes to mind as to why this could be happening? If I don't use the refresh rate functionality, it doesn't happen.

I have tried launching in portable mode, same thing. This happens both with Kodi 19 and Kodi 17.6 DSPlayer (which switches through madVR). So I'd be inclined to say it's not strictly Kodi dependent. But if I play back a video with MPC-HC, it switches refresh rate correctly but when I exit the player nothing happens, it goes back to 60Hz and stays that way.

What does Windows say the default resolution of your monitor is? What does your graphics card say it is? What does Kodi say it is? I suspect there's a discrepancy there somewhere.

Is there a “default” resolution in Windows? Where do you see that? Same for the GPU… if there is one, I guess it’s 2160p60, that’s how drivers set up the resolution when newly installed.

Kodi always starts at desktop resolution/refresh.

I found with DSplayer, I have to let kodi do the refresh rate switch, otherwise I get that same problem you have described - just my experience.

A display device 'tells' this to the GPU driver and the OS in its EDID.
You can read the EDID with e.g. EDIDViewer and there you'll see a 'preferred' timing mentioned.
This is the one that is used when installing a new driver.

Solved it! In Kodi System/Display settings, under resolution, there were two 3840x2160p resolutions. One for 50Hz and one for 60Hz. For some reason, the 50 Hz one got chosen. And that was messing things up.

Oldpainlesskodi, I have madVR handling refresh switch and it works correctly (now).

I'm using Kodi with DSPlayer too. Have you noticed when you start a video, that you get a black screen for 5 seconds, but you do get audio?

@ashlar42 - seems that was my issue too. Thanks.

That depends on how quick your TV is in switching refresh rate, I suppose. Regular Kodi has an option to delay the start of playback to accomodate that. I don't remember if that worked for DSPlayer with madVR or not. The new TV I'm using is almost instantaneous in switching, so I haven't thought about that.

Oh, wow! Glad to have been of help.

Sorry all for the semi-offtopic, btw.

[ashlar42]

One question I have. I ended up going back to old, trusty Reclock (thanks to redfox for making it Win10 compatible). I forgot how easy it is to get perfectly smooth results with it.

Since that exists only in 32 bit, am I missing something in madVR by not using the x64 build? Or in LAV filters, if you know something...

Everything seems to be working perfectly but I might be missing something.

[HillieSan]

Why did you install reclock? Didn’t madvr work for fine after a fresh install? It worked fine for me.

@ashlar42

Reclock is a good audio renderer, I've been using it for years. I don't think you will miss something at 32 bit.

[nevcairiel]

32-bit will be limiting you sooner or later. Software decoders are significantly slower on 32-bit, and hardware decoding won't engage for very high resolutions due to memory limits (> 4K, I believe, its driver-controlled). It might work today, but it does not have a future.

Some of us are still using reclock, and that is why we stick to 32 bit, the other 64 bit alternatives are not so good.

I installed Reclock not to have to worry about precise refresh rates. I hate dropped/repeated frames. I always notice them when watching video content. And I wasn’t managing to keep 10 bit when creating custom resolutions.

Sure, but I just bought a 4K TV, won’t care for 8K content for a long while (if ever). If I don’t miss anything up to 4K HDR content, I’m not missing anything. Having said this, I have checked, a RTX 3070 supports VP11 which includes "maximum resolution of up to 8192 x 8192 pixels (8k resolution) for all HEVC and VP9 profiles", up to and including Main 4:4:4 12. I think I'm covered on that front.
