madVR - high quality video renderer (GPU assisted)

[fedpul]

Can you send me your exact madVR settings, and maybe a sample video with which the problem occurs? Then I'll try to reproduce it here. Also please let me know which LAV settings you're using (software decoding or copyback or native DXVA or ...).

The madVR settings are stored in "madVR\settings.bin", if madVR has write access to that folder. Or in HKCU\Software\madshi\madVR\Settings otherwise.

madshi, I am very busy this week, I need to study very hard for a really important university exam. Next week I will be reporting the things you asked for.

Thanks in advance.

Quoting myself (again).

Also I think banding is unbalanced, low is almost no-op.
In a 10/10 scale is as if low was 2, mid was 4 or 5 and high 10, Whereas something more balanced could be 3, 6, 10.
I suggest to raise "low" one notch, and "mid" one or two notches above.

Also thinking out loud here, but could it be possible to add some "software" based anti-strobing effect, I mean I see how I could use it for "cinema mode". I know some Smart TV's have the option but it is actually hidden, not very self explanatory nor very accessible for the daily use, so having it set in madVR software with rules could be a nice addition. This would involve inserting a black frame every other source frame, then the TV changing to this framerate mode (47.95FPS for films). Have I said something stupid or could this actually work?

edit: btw I get constant frame drops when changing from display to another, as if madVR didn't unhooked the video drivers at all. That is watch a movie on TV, close the player, switch to monitor (other resolution, color profile, etc), play a video, major frame drops... it eventually fixes after playing some videos or so but it's annoying.

Having something similar here where second display get frame dropped (render queue report or 0-1 1-2 iirc). That is .8901. Revert back to .8816 and no issue.

I see didn't know it was version dependent, I update periodically (although for now have stuck to 0.88.21) and I seem to always get the frame drops.

[James Freeman]

Can anyone please test for video freezing after pause and unpause several times.
I will try to find in what version this appeared.


EDIT:
Okay, found it.
89.0 introduced it, 88.21 is OK.

Try pause and unpause (space bar) repeatedly and look at the Play/Pause OSD.
The OSD should stop responding, and when you pause the OSD will stay/show "Play" even though the video is paused.
Now unpause and the video will freeze.
Wait 10 seconds and pause and unpause the video, you should see the video speed up to its current position.

I'll take a wild guess and point the finger at this:

* increased seek "black screen protection" to 2 seconds (formerly 1)

EDIT 2:
It happens only in Overlay Mode.
madVR sometimes shows something in RED font and disappears very quickly, I can't read it.
MPC-HC sometimes crashes at opening (without loading a movie).

Firstly, hello.

I've been using MadVR for about 12 months now and I love it, despite my slightly under powered GPU. Good work Madshi.

Last month I bought a 4K monitor and i've noticed 1080p vidoeos aren't quite as crystal clear as they were on my AOC 1080 monitor using Potplayer, and upon using MadVR my GPU went haywire.

I have a Sapphire Radeon R9 270x, so I figured i'll upgrade. Now I was thinking of a GTX 970, but as i'm trying to upscale to 4K, do I need something with a bit more power? I don't game at all, just watch videos. Any recommendations?

I was eyeing the 980ti but that seems extreme overkill (and wallet killing), though I believe MadVR is very taxing on the graphics card.

[huhn]

just change the upscaler. the r9 270x has plenty of processing power.

[bcec]

super-xbr combined with SuperRes 2:0.7 results in hotter gpu (== more fan noise) for me compared to nnedi3@64 alone (no SuperRes). Render times are about 10ms faster with super-xbr & SuperRes combination, so I am not sure why GPU is warming up quite a bit more. Any ideas? This is for a 1080->2160@23Hz upscale on a GTX970 and Win7.

[aufkrawall]

Different shaders lead to different power consumption.
The GPU load display doesn't give information how well certain parts of the GPU are used. A high power consumption is a sign of high ALU load.

If you aren't into gaming then a GTX 960 would be a better choice. The GM Maxwell 206 chip has superior decoding capabilities(h265/HEVC at 60Hz 10bit Main Profile). 4k videos works fine with GTX 960 ,no problems comparing to a GTX 970.

[aufkrawall]

He's talking of upscaling to 4k, not playing 4k video.
A 970 would be much faster there than a 960, at least with NNEDI3 or SuperRes you definitely need the performance.

Probably fastest for this task would be a Fury card. But I'd wait first and see if the fix for NNEDI3 NV will also fix the PCIe copyback issue with it on AMD.

[GCRaistlin]

Back to my previously asked question. I need to upgrade my 8800GTX card to something else. I have Epson EH-TW9200W (FullHD projector). The possible choices are:

1. 4870
2. 4890
3. 5670
4. 5750
5. 5770
6. 6770
7. 6850
8. 7750
9. 7770

huhn said that any 128-bit GDDR5 card can do NNEDI3 for SD. StinDaWg said that 7850 is the minimum for NNEDI3 for 720p>1080p upscaling.
Do I understand this right that none of above cards can do NNEDI3 for 720p>1080p upscaling and I may buy any of them to get NNEDI3 for SD?

The GTX 960 is pretty slow, it will not be able to do NNEDI3, but it does support HDCP 2.2 on its HDMI 2.0, unlike any other GPU currently available.

Yes, they will not do NNEDI3 720p -> 1080p. I am not sure about SD but I would trust huhn. However, if "SD" includes 1024x576 DVD rips I would expect some of those cards to be a bit too slow.

Then what to choice from the list? What is the bottleneck for madVR - memory amount, 128-bit/256-bit, core speed, memory speed?

the 128 bit isn't very important for performance using madVR. back in the days card without 128 bit GDDR5 had a very bad price/performance ratio.

i'm pretty sure my old 6770 was able to use 64 neuron for SD upscales and pretty sure 16 worked to for 720 -> 1080 23hz. but i don't use this card anymore.

new cards below the r7 250x aren't worth there money anymore things changed...

7700 and r7 250x are both Cape Verde the r7 240 is all ready down to half the performance and there is at least one r7 240 with 128 bit GDDR5 so i'm wrong to day ^^ but 16 neuron shouldn't be impossible for SD so maybe it still counts...
the 7770 should work.

there is a chance nnedi3 will get a lot faster for AMD cards soon.

[aufkrawall]

But probably not regarding the neuron count.

thank to it you can use more so doesn't matter.

Aren't the Fury cards power hogs? At their price the 980ti seems like better value to me overall. Bit of a shame the 970/980 didn't get the same HTPC features as the 960.

I definitely need to upgrade my 270x though. Using any reasonable enhancement in any of the Chroma options makes my card sound like a jet engine, and on 4K videos it causes huge stuttering. I'm not even sure what it's doing to 4K videos either tbh, they don't need to be upscaled or really improved in quality.

The 980 (non ti) seems the sweet spot for me at the moment. Not too overkill like the Ti but can handle the extra grunt for 4K over a 970. I just don't want to spend money on one of these expensive cards only to find out it struggles at 4K res though, and I know for Gamers no single GPU can handle 60FPS at the moment.

The Fury Nano has 8.2 TFlops@185W TDP.
I could imagine that the theoretical computing performance is not unimportant for NNEDI3 or SuperRes.
However, it's not actually proven yet, so I might be wrong.

Hm, I don't think there's much of a difference between 980 and 970. Also 970 can do 1080p30 -> 4k with 64 neurons and 980 still can't do 1080p60 -> 4k 64 neurons.
I think someone here with a 980 Ti wrote that it would be possible. But probably even Adaptive Sharpen on top of that would be too much again.

This happened last generation too. The mid range cards are newer chips.
Pascal is going to be a big deal so expect at least twice the performance, it's due mid next year, so it's not that far off.
