madVR - high quality video renderer (GPU assisted)

[Aleq]

I had the same issue as Superb - suddenly (after many minutes of flawless playback) the frames started to be inconsistent - something like 1-2-3-4-...here it start...-2-5-3-6-.... (this does not precisely describe what happend, just my feeling that the order of the frames was suddenly mixed within a consecutive set of let's say 15 frames).

Guys, I must be blind but where do I set the refresh rates/resolution in madVR as I have seen it's recommended to try madVR resolution/refresh changer instead of the one in MPC-HC? Thans in advance.

Don't feel bad, I had the same problem a few pages back cause I didn't see it either. :D

I've noticed more of a problem when ReClock is in the chain combined with a monitor that cannot change it's refresh rate. If I use ReClock and set MPC-HC to change the fullscreen refresh rate of my HDTV I get 0 glitches. Maybe a single delayed frame and a few dropped frames at the beginning. If trying to playback 23.976FPS on a 60Hz only display ReClock will interfere somewhat with MadVR as ReClock cannot match the refresh to the FPS. I guess this is normal. But without ReClock it behaves a little better in that situation. I wonder how many are watching on computer monitors with a fixed refresh rate compared to a HDTV which supports multiple refresh rates. Also I wonder how many are using ReClock. Only using all of MPC-HC's internal filters and no external filters is fair when trying to debug MadVR I would think. Even I forgot to do this (apart from disabling ReClock) when posting my results. Which may make any results worthless.

Saying that however I am getting great results using default settings and only ticking the three sub option boxes (in MadVR) using my HDTV. The only issue I have run into is when some anime videos do a weird framerate change part way through or where there was a scrolling text section and they encoded to 23.976FPS. MadVR goes into this repeating frame judder when that happens. (No idea why the scrolling text would make MadVR bug out like that since it's 23.976FPS throughout the episode).

BTW is there any way to capture the stats display to a file? Or a logging option I have missed? I think it would be far better if people could post their results in a manner where Madshi can see which options were enabled and what the stats were. Not sure why he has not done this rather than asking us to post spurious details that are less objective.

The scrolling text probably bugged up the encoding (nothing you can do about it).

[oddball]

The scrolling text probably bugged up the encoding (nothing you can do about it).

No I don't mean the usual jerking you get with scrolling text sections in some anime. I mean it actually affects playback. If I hit arrow left to go back a bit it does not do it other than the usual scrolling text jerkiness. It's an entirely different effect. MadVR (Or MPC-hC or perhaps a combination of filters I'm not sure) does a weird repeating frame thing like it's bouncing between each frame several times. I've only seen this happening since build 0.61 and the latest MPC-HC and ffdshow (I tend to update them all at the same time for each build).

[oddball]

I'm unable to get the MadVR resolution switching to work correctly. It supposedly overrides MPC-HC's fullscreen modes. I have it set thus.

1080p23, 1080p50, 1080i50, 1080i59, 720p23, 720p50, 720p60

I have 720p60 because I do have a true 60fps video I use to test.

Whenever I playback a 720p 23.976FPS file video it always defaults to 1080p23. However if I play a 720p 29.97FPS video it always defaults to 720p60.

Also when playing back 1080p 25FPS .ts files it plays at 720p60 (even if I use ReClock to PAL speedown).

Am I doing something wrong? I can understand if my HDTV does not support 720p at 24p/Hz but the .ts files are throwing me somewhat.

EDIT: OK changing 720p60 to 720p59 sorts out the .ts problem. But I still have 720p23 ending up as 1080p23. Could that be because my HDTV does not support 23/24 @ 720p?

[djsolidsnake86]

srt support is possible?

[Superb]

srt support is possible?madVR already provides the players with the interface they need to render subtitles. It works well w/ MPC-HC (and probably other players, like PotPlayer).

[djsolidsnake86]

well srt for me doesn't work here
only subs integrated in the file seem

[Superb]

well srt for me doesn't work here
only subs integrated in the file seemIt works perfectly. Tested w/ both avi and mkv files. I'm talking about more than 30 different files. Something is wrong on your end.
Make sure you use the latest (http://www.xvidvideo.ru/) MPC-HC and its internal subtitle renderer.

EDIT: btw, writing "it doesn't work for me" w/o providing us with the details (player? version? filters involved? player's settings?) is not going to help you...

[Qaq]

But what I'm *really* interested in is whether you still have glitches or not. The purpose of the D3D11 option and all the other new tweak options is to get rid of glitches.
Just tried v.061 with high bitrate 1080i/29 video. ATI 5450, win7, source&display both are 1080/29.
It seems I only have glitches with D3D11 option... enabled. With D3D11 option disabled I found that I need all the other new tweak options enabled to get less dropped frames (present queue reaches 0 in dynamic scenes). Thats for high bitrate 1080i/29 video.
In same time I have zero glitches/drops for low bitrate/resolution video with D3D11 option enabled. So I think D3D11 is a useful feature, I just shouldn't use it for "heavy" video with my little ATI 5450. Sorry for my terrible english, I do my best :)

[pacemaker1000]

Not sure if this is already known or even cared about but in my search to get sd dvd playback with madvr (thanks madshi for the link earlier) i used the qdvd hack for ripped discs. due to the menu problem on Win7 this did not help with dvd discs, although there are some trying to get a non ms dvd menu system working. however in the meantime using anydvd and selecting 'main movie' gets around this and i can now watch my collection using madvr :)

[dansrfe]

madshi, the lock/unlock when madVR is running is a HUGE problem for me...it didn't exist pre 0.54 or something like that. Please look into it if you have time.

[oddball]

Can anyone else with a dual display Nvidia setup confirm that the seekbar appears when they move the mouse cursor to the bottom of both displays please (It should only appear on the playback display when the mouse cursor is on that display only). It did not do it in 0.58.

[pankov]

I've reported the same problem a couple of days ago and madshi said that it's kind of intentional which puzzled me but I decided to leave it for later discussion cause his focus at that moment was on the glitch fix.
Edit:
Sorry for the confusion
I've just re-read his comment and he actually said that he is aware of the problem and the fix is on his to-do list.

[oddball]

Ah OK I must have missed that thanks.

[thuan]

I've just upgraded my GFX card to a nvidia GTS 450 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121415&cm_re=asus_gts_450_dc_oc-_-14-121-415-_-Product) and all my problems with accelerated playback (H.264 and stuffs that I raised in this thread (http://forum.doom9.org/showthread.php?t=159486&page=4)) and rendering glitches with madVR have gone. I don't even need to turn on any glitch hacks. I can even play the girls clip in that other thread which is 1080p/60fps perfectly fine with LAVCUVID. Yatta, I love you guys. The only thing I miss now is screenshot capture in madVR. Patiently waiting :D.

EDIT: Just played an entire anime music video of One more time, One more chance in 1080p/24fps, only 2 glitches when I went full screen. I'm happy.

where is the internal subtile renderer in mpc hc?

in mph hc i don't have any internal filter active, i only use klite codeck pack filters
filters used are ffdshow video and audio

[toomyzoom]

Hi madshi, thank you for your excellent work on MadVR. Now I can change to my custom refresh rate at 48hz which mpc-hc can't do. However, the display mode didn't work together with reclock. Lol, it made me wonder for awhile, thinking the changing refresh rate was a hoax. Then I read this http://forum.doom9.org/showpost.php?p=1497194&postcount=7564, disabled reclock, and the damn thing started kicking. Can you make it displayer mode changer work with reclock? I know I can't live without it anymore after experienced the smooth and synced playback.

P.S.: The 0.61 version work with reclock but I got performance issue with sutter and out of sync for few milisecond. This problem didn't exist in 0.58 with same settings.

[toomyzoom]

Does anyone know how to change refresh rate by framerate token on filename? I don't know the syntax for framerate token.

Madshi. I have been trying out test videoes from this thread.

http://forum.doom9.org/showthread.php?t=159486

I am unable to playback Birds 1080p60FPS smoothly with MadVR. The only renderer that plays back smooth(ish) is Overlay. I am using CoreAVC as the decoder and it puts very little strain on the CPU. However when I play the Girls clip which is 1080p60FPS in a MKV container it plays back smooth as silk. I do not understand this as both clips are 1080p60FPS. Yes I know the MP4 is a different codec and container but it decodes fine in overlay and CoreAVC plays it back seemingly OK. But when MadVR is the renderer it drops tons of frames. Why is it harder to render one 1080p60FPS clip then the other?

BTW using DXVA with the 40mpbs 1080p60fps VC1 WMV clip from this thread

http://forum.doom9.org/showthread.php?t=156660

I can play smoothly only with DXVA and Custom EVR but I get green corruption all over the place. Not related to MadVR but I find that odd nonetheless.

I have an Nvidia GTX560 which should handle most video (emphasis on should).

Also of note. Windows Media Player plays back Birds and that WMV clip perfectly.

EDIT: Actually I can't get the Devil May Cry WMV to playback smoothly over than with EVR but then I get the green corruption. Haali renderer gives the clearest + smoothest (it does not give green corruption) but still lags somewhat compared to EVR or EVR CP.

[oddball]

The Birds clip gives MASSIVE frame drops. I am going to try a few of the MadVR settings to see if any help. GPU load is 6% using CoreVAC and CPU load is 38% so it's not those that are the problem it would seem. Also MadVR scales the target rectangle to 1920x1080 correctly on the HDTV so it's not that causing the massive frame drops either.

[oddball]

OK here are my findings.

CoreAVC latest build + MadVR = no go on that Birds clip. Stutters and dropes hundreds of frames.

LAV Splitter + CUVID decoder + MadVR = no problems.

LAV Splitter + CUVID + MadVR + ReClock = Mad stuttering as mentioned previously on the Devil May Cry 1080p60fps clip. This appears to be the real culprit in regards the weird stutter effect previously mentioned by me and a couple of other people. Run that Devil May cry clip with ReClock in the chain and it will probably show it to good effect.

EDIT: Nope it's not ReClock. It's still stuttering. Damn! I thought I had it figured too. Please can others tyr the Devil May Cry clip and see if they get weird stuttering.

[6233638]

I have not been able to test those video files yet, but would like to comment.

Right now, I have had to stop using LAV Splitter in my system after just trying it these last couple of weeks, as I am getting random hangs for 10-30s during video playback two or three times throughout the duration of a Blu-ray film. After going back to using the internal MPC-HC splitter (nothing else seems to do as good a job at providing data on Blu-ray streams) this has completely disappeared.

I appreciate the work being done on the splitter, but it doesn't seem like it's quite ready yet, so you may want to try something else. (either the internal MPC-HC one or Haali's)


I have recently started trying LAV CUVID as well, and that seems fine so far. Once I have the time, I plan on testing power consumption to see if there is much of a difference using it or the CPU to decode.

[oddball]

I seem to be having better luck without LAV Splitter too. With LAV Splitter installed playing the Bird MP4 file I was getting 2 frame drops. Without I am getting 0 drops.

[cyberbeing]

oddball, could you try the following with Software vs CUDA decoding with the fixed vsync thread priority madVR 0.61 build (http://madshi.net/madVRvsync.zip) and Haali Media Splitter?

Disable Desktop Composition (Aero), Disable Fullscreen Exclusive, Disable all 'tweaks', Disable 3DLUT.

Set chroma resizing to Bilinear (for testing, in order to essentially eliminate re-sampling GPU load).

Set Windowed mode flushing to the following:

Number of backbuffers: 3
After intermediate render: No Flush
After last render step: Flush
After backbuffer: Flush & Wait (Loop)
After present: Flush & Wait (Loop)

Also try:

Number of backbuffers: 8
After intermediate render: No Flush
After last render step: Flush
After backbuffer: No Flush
After present: No Flush

This is to satisfy my curiosity more than anything else. My brief experience of Fermi + madVR + Win7 is rather outdated at this point.

[oddball]

I may come back to those suggestions but right now I think I have it cracked. Using internal MPC-HC splitter (Haali Matroska Splitter gave me big problems when switching between a FLAC 5.1 audio track and a DTS 5.1 track embedded in an MKV) + CUVID + MadVR 0.61 non-vsync mod gives smooth playback using just the two bottom sub options on preframes (I don't think seperate thread would make much difference though). The Birds clip gives 0 dropped frames and 0 glitches. Same for Devil May Cry clip. All I get are initial dropped, delayed and glitches at the beginning of playback but not after. I am gonna watch a long movie and see though (Makes note of stats).

[cyberbeing]

If you found settings that worked with Fullscreen Exclusive, don't worry about testing mine. No point in using Windowed mode if you get Exclusive mode working well.

That madVR build isn't a vsync mod, by the way. It just reverts a minor change made in 0.59 relating to thread priority. It doesn't add/remove threads or change any underlying vsync code. If you do end up testing my Windowed Mode settings, please use that build, otherwise it invalidates your results in comparison to mine a year ago. I have ulterior motive, and really am only interested in your Fermi results if you match my old Fermi configuration exactly as described (removing variables). Of course, you don't have to humor me if you don't want to. :devil:

[pie1394]

Hi madshi,

Tried the following combination for many BS system TS files. The interlaced moving scene is not smooth at 1080i59 output w/o deinterlace. But it is ok at 1080p59 ouput w/i deinterlace + frame-rate doubler from LAV CUVID.

It looks similar to judder on quick horizontal moving objects as if 1 field contents of the video are absent.

My TV is Hitachi ALiS PDP and it does not need any deinterlace processing upon 2 following cases for 1080i output signal:

1. No vertical video scaled 1080i image is output to corresponding 1080i output signals (or 1080p50/p60)
2. Output video's vertical pixels are 0.5x or less than original video's.

ps: At the 1920x1080i50/i59/i60 modes, It still shows the refresh rate at 50 / 59.94 / 60 Hz according to madVR OSD info.



OS: Win7 x64 SP1
GPU: GTX 260+ / Forceware 270.61
Player: MPC-HC 1.5.2.3052
Demux: LAV Filters 0.24
VideoDec : LAV CUVID 0.6
AudioDec: LAV Audio decoder
VideoRender: madVR 0.61

Video: 1440x1080 / 1920x1080 type MPEG-2 contents 17 ~ 4x Mbps + LC-AAC / AC-3 / DTS

[Hprd]

Ok Madshi, i have a question reguardling the fps override via renaming, and how the osd interprets that and whatnot. For example if there's a video that's 29.970 fps, and i want to play it back at 60hz (i have a resolution manually set to 60hz in the nvidia console, not the default 59.9) is it better to put 59p in the filename (to preserve the framerate, judging by the osd), or 60p? As if i put 59p, frame repeats happen a bit more often than 60p. And going by eye it looked like the osd wasn't lying, or maybe i was seeing it wrong?

So basically, is there any downside to not having the fps preserved perfectly/does it result in smoother playback, with no side effects? Or is the osd just showing what i'm telling it (and does it mean though that it repeats frames due to this more often?)? :thanks:

And as i said b4, i get no glitches like this anymore (59/60p in the filename) :cool:

[dricks2222]

To obtain a PERFECT fluidity with a LCD monitor and madvr (i have a 226bw), all you have to do is to add a custom resolution with a refresh rate of 47.952 (23.976*2) OR 71.928 (23.976*3)

I'm using a Samsung 226bw (22' at 1680x1050) and it works perfectly.

Here is how to do it using NVidia panel control :

http://www.upl.co/uploads/screen-1.png

http://www.upl.co/uploads/screen-2.png

http://www.upl.co/uploads/screen-3.png

To add a 72hz (71.928) resolution, follow the same step but set the top refresh rate at '72' instead '48', and the bottom refresh at 71.928 instead of 47.952

And voila, have fun !

http://www.upl.co/uploads/avt-small-0.png (http://www.upl.co/uploads/mpchc-20110429-20321801.png)

http://www.upl.co/uploads/avt-small-2.png (http://www.upl.co/uploads/mpchc-20110429-20344676.png)
PS :
Yeah, i still have 1 frame drop every 30 minutes or so at 47.952 and every 45minutes at 71.928 but i think i can live with that ;)

[SamuriHL]

But I can get the same result with 23.978 custom res. :)

[dricks2222]

Of course, i'm talking about monitors that doesn't support 23.976 native refresh rate.

For example, most PC LCD (mine included) doesn't, while they will support 47.952 without a glitch ;)

Also, you can use it to max out your refresh rate. For example, samsung says that the 226bw support up to 1680x1050 @ 77hz.

So i made a similar profile @75hz, which means +25% FPS in high action games. Lovely :D

[SamuriHL]

Ah, I see. Very nice then. :) I use HDTV's for my gaming needs on my PC's so I guess I didn't think of the case where people are using actual monitors for madVR.

[Mark_A_W]

Ah, I see. Very nice then. :) I use HDTV's for my gaming needs on my PC's so I guess I didn't think of the case where people are using actual monitors for madVR.

Yeah, I use a CRT projector and a CRT monitor running off a video switcher, so I had to find a resolution that worked for both.

The projector is in the Home Theatre room, and the PC is on a desk in the next rooom with cables running through the wall. I'm typing this on the PC now - it's my general use PC. So I do all my cuing up of movies, and madVR testing on the monitor (and watch TV too), then walk into the HT to watch a movie.

I hope/plan to move to an LCOS/SXRD 3D projector soon, but again, I'll need to split the signal with an HDMI splitter. So I need to find a PC monitor that will run 1920x1080 24p at the very least - not easy as far as I can tell.

[oddball]

I guess it's OK if you like flickervision. btw MadVR reports direct3d failure at that rate on my LCD.

[Mark_A_W]

LCDs don't flicker. Plasmas do (mine runs 24p at 48hz and there's still a slight flicker).

Perhaps I should have said "accepts" 24p, and runs it at a clean multiple (not 60hz!!).

[oddball]

Yeah my HP LP2375w flickers slightly at 48Hz. Not that I use it for viewing HD movies anymore. I would have liked to get 72Hz out of it though but could not find a way to do it. If I forced to 72Hz it looks all garbled and I don't know if there is a custom timing to fix that. If you know of any custom setting to try and get 72Hz I'll give them a go.

[Thunderbolt8]

To obtain a PERFECT fluidity with a LCD monitor and madvr (i have a 226bw), all you have to do is to add a custom resolution with a refresh rate of 47.952 (23.976*2) OR 71.928 (23.976*3)

I'm using a Samsung 226bw (22' at 1680x1050) and it works perfectly.I've got a 226CW, but an ATI graphic card. do you know what I need to do here to achieve the same effect?
no matter what I seem to do, madvr always keeps telling me my display Hz is 59,88 all the time :(

[Mark_A_W]

It flickers at 48hz? Obviously I withdraw my comment about LCDs not flickering.

[6233638]

It is almost impossible to get a perfect 24/1.001 out of a PC to sync up with files (even though many are 24.000 on the disc) so Reclock is essential for smooth playback anyway.

Yeah, i still have 1 frame drop every 30 minutes or so at 47.952 and every 45minutes at 71.928 but i think i can live with that ;)Any frame drops during film playback are obvious and unacceptable.

I hope/plan to move to an LCOS/SXRD 3D projector soon, but again, I'll need to split the signal with an HDMI splitter. So I need to find a PC monitor that will run 1920x1080 24p at the very least - not easy as far as I can tell.My recommendation would be to go for a D-ILA projector. SXRD has longevity issues, and I have never seen a high-end device using "LCoS". (typically cheap pocket projectors or budget models these days)

I have had a 3DTV for about 6 months now. I don't feel that 3D is worth it. Most pre-baked 3D content is not tuned well I feel (wrong convergence/depth) and while I can play games in 3D at 60fps on my new system, after a couple of days of building it and buying the 3DTV Play kit, I haven't gone back to it. By all means buy a projector that supports 3D, but don't choose a specific model for 3D.

I only have a 3DTV because I had to get one to get an LED backlit LCD rather than edge-lit. It was a nominal fee to add the 3D glasses, which is the only reason I have a pair.
LCDs don't flicker. Plasmas do (mine runs 24p at 48hz and there's still a slight flicker).

Perhaps I should have said "accepts" 24p, and runs it at a clean multiple (not 60hz!!).All good displays flicker. For me, plasma flicker is worse than CRT at the same refresh rate. Even 100Hz plasma is unwatchable to me.

I had a CRT running at 48Hz for quite some time without too much trouble. (but after a long day, I didn't want to watch it)

High end LCDs also flicker using backlight scanning. This is the least intrusive flickering of a display that I have seen, but even then I will sometimes disable it if I feel a headache coming on. (it's rare, but happens maybe once or twice a month)

Actually, most LCDs also have a habit of flickering when you turn the backlight down. It was not a problem with older models, but they do it differently now to save more energy, which results in it flickering. (and a slight buzz from the display many times)
