madVR - high quality video renderer (GPU assisted)

If you do see a difference in madVR, can you please make a screenshot showing the difference, please? Thx.

Screenshots:

If your retest confirms your first impressions, can I have a sample, please, with which I can reproduce the smoothness difference? Thanks. After reading robpdotcom's comment (see below) maybe you should try installing 10.11 drivers?

Why 10.11 drivers? Did you mean 11.10? I'm already using 11.10 which are the latest non-beta.

Can you try this sample with my filter set.

PotPlayer 1.5.29996
(1) Haali Media Splitter 1.11.288.0
(2) LAV Video Decoder 0.38
(3) Madshi Video Renderer 0.78
(4) Audio Codec/Transform
(5) DirectSound Audio Renderer

MadVR Settings




Also you should switch audio processing only in full screen mode.

Yes it does. Potplayer decoder with "DXVA without rendering" option turned on can use hardware accelerated playback with madVR. Mostly I use CUDA decoders, but for ATI users that can be an option. I've tried Cyberlink(HAM), another decoder which supports hardware accelerated video decoding with madVR, works fine, but madVR deinterlacing is not working.

At this point, it seems that Windowed Mode just doesn't kick the thing into gear, so to speak. Everything works and looks great in FSE mode (higher clocks), but Windowed mode doesn't. I'm really not sure what's going on here all of a sudden. I tried the "profile trick" mentioned above, that had no effect. I'm on the 11.10 drivers and I'm going to try locking the clocks to see what happens.

I was having the same issue as you on my 5750 - the deinterlaced video simply was not smooth. 10.11 was the newest driver that worked for me. Then, there's this:

I have that one installed, chose the new interface. And i use Realtek's ATI HDMI driver. All is fine since, and i have never updated till now, since i see no reason for it and there are now important features added or important bugs removed since then. They only seem to work on game related stuff that doesn't interest me.

My HD5770 has worked like a charm with this driver, so im not eager to upgrade :-)

For me, 10.12 had the same problem as the newer drivers, but 10.11 was perfect. And like GMC said, most changes to drivers are game related, so unless you play games, you probably don't need the newer drivers.

Also, using the revamped CCC had problems for me - one being that it wasn't showing the option to change the dynamic range to 16-255 (limited), as well as a lot of other options in the video "enhancements" menu. 10.11 with the old CCC has no problems, so I'll stick with that. I am, however, using the latest AMD HDMI audio driver - the older versions had issues with outputting Windows sounds (such as the sound you get when you click on a folder).

It's just as smooth as EVR; but it's madVR, so it's even better.

Here's the sample. If you want more, just ask - I have lots of them.

Seems to work mostly as intended for Intel HD3000 but I've only tested with a MPEG2 60i SD source so far, MPC-HC DXVA decoder used.
Some unexpected behavior: When i hit ctrl+shift+alt+d I see no combing yet the annotation says de-interlacing is off.

- TV is doing the deinterlacing?
- Source video, despite being 60i, is not really interlaced (i.e. both fields have no temporal differences between them)?

MPC-HC DXVA decoder used

Is it really being used? I suspect MPC-HC's internal software decoder which does some deinterlacing by itself might be being used (check the Play-> Filters menu).

EVR might be cheating. It has some auto-magic to reduce deinterlacing quality when it notices your GPU is hitting its limits. It sadly doesn't let you know when it does it.

It's done in the driver. For Radeons, it's an option called 'enforce smooth video playback' or similar. Turn that off and it wont down grade the deinterlacing.

No, thats not it. EVR has the same functionality, it can go down from 50/60p output to 25/30p, as well as use a different algorithm if the driver offers one.

The ESVP option is not done at runtime, afaik, its only decided based on your GPU which algorithms are active - not if it actually manages to do it, just if a developer thought it would.
Note that the EVR option is not always 100% successfull, especially if the driver forces some options to be active.

No, I'm viewing through a computer monitor. Just tried FFDShow for decoding and the behaviour is unchanged and futher motion is very jumpy regardless of field order setting via ctrl+alt+shift+f.

Yes it was really used per Play>Filters. BTW how do activate the Intel decoder? I ticked the boxes in MadVR setting and added the seperate dll to the MadVR folder.

EDIT:Tried MPCHC decoder again and noticed motion became jumpy after cyling de-interlace on and off.

I doubt that's the case.
It looks perfect both with test samples from AVS and with live sports. It's the same quality wise as madVR and LAV CUVID with High-Quality Processing turned on.
The load difference is similar if use lighter samples which leave a lot of headroom on my video card.
Nev, you are using a pretty decent NVIDIA card, right? Do you see the same performance difference?

[whitestar999]

i am having an unusual problem.some 1080p videos run fine on my laptop c2d 2ghz mobilty radeon 4570 with screen resolution 1366*768(60hz) but when i try to run the same video from laptop through hdmi on a 1080p(60hz) LG LCD TV there video lags with frames dropping continuously.backbuffer & render queue are almost always 1-3/8 while decoder & other queue are full.as i understand playing 1080p video on a 1080p screen should be the easiest case scenario or am i missing something.

[namaiki]

whitestar999: How much video ram does your card have? Also, if you make the video window smaller while connected to the 1080p screen, does it still lag? Try check with GPU-z or similar program if the GPU core or memory is being maxed out.

[whitestar999]

@namaiki,card ram is 256mb & yes there is a difference when i make video window smaller.gpu-z shows card load at ~70% when window is resized to ~480*360.how can i see the gpu-z window in full screen video playing?

[namaiki]

You could try put GPU-z on the other monitor or only just maximize the player window instead of fullscreen. Have you checked if the GPU clocks are at full speed?
256MB is just on the limit. My computer with a 9600M GT 256MB before it died was only just enough for madVR at 1920x1080 30fps.

You don't need to see it, just enable 'log to file' and 'continue refreshing'.

[diizzy]

Thanks for all the hard work you've been putting into madVR, I do seem (?) to have some issues with the new DXVA2 deinterlacing feature.

At least on Intel HD Graphics (1st gen Core iX-CPUs) it doesn't seem to work at all, it just says "deinterlacing failed". It does work with Microsofts DTV filter on the other hand...
While I do realise that I have hardly the most optimal hardware for madVR I have to say that it works pretty well with some minor adjustments and doesn't provide slideshow performance when going above 1920x1080 which EVR CP and other renders do (1920x1200 makes it crawl for some reason).
If you want me to do some kind of debugging please let me know.

As for the posts above at least on this computer windowed mode needs much more processing power when exclusive (full screen mode), I do need to adjust the scaling algorithms somewhat otherwise I get noticable frame drops even in exclusive mode. Using Softcubic as algorithm instead of lanczos (default) seems to do the trick on my "low-end" GPU at least so it may be worth a try. I'm sure madshi can provide information on which algorithms requires less processing power than others.

Best regards,
Danne

Curious, it says "VideoProcessBlt failed (8007000e)", and thats the HRESULT for Out of Memory. How much memory did you allocate your IGP?
