madVR - high quality video renderer (GPU assisted)

As madshi said this seems to be XySubFilter related, but I happen to recall having a similar issue with ffdshow which could be solved by going to the ffdshow options, then "Subtitles" and then disable everything under "Subtitle sources", in particular "Embedded subtitles". If that doesn't work you should try asking in the XySubFilter thread.

Doesn't matter right now. It(dx12) will ship in late 2015, most probably with win9 (it's usually 3 years between major win releases).

With regard to the external DVD subtitle problem, the behavior that I have observed is:
A subtitle that has to be displayed at time X is not displayed when video is at position X but when playback has been active for X amount of time. Seeking has no effect at all.

this problem doesn't happen with vmr9 renderless, for example.

Can anyone confirm this?

I guess madvr doesn't like dvd navigator filter which replaces lav splitter when playing from dvd.

Windows 8.1, intel hd4600, latest mpc-hc & madvr.

This in know problem with ISR and madVR and how they handle subtitles for DVD or timing in fact. And I totally forgot about it being that I don't watch DVD that much anymore and never with external subtitles

This build should resolve this issue https://www.dropbox.com/s/kifqfx7li1w75az/MPC-HC.1.7.3.119.x86_ISR_DVD_TIMING_FIX.7z I noticed few other (very) minor issues, but I will deal with them later.

Also could we move discussion about MPC-HC to its own thread?

Hi madshi,
A rather annoying cosmetic change has occured between builds 0.87.4 and 0.87.5.
I'm using the vanilla MPC-HC standalone VSfilter v1.7.3 here
In 0.87.4 and all previous versions of madVR (and all the other video renderers), switching the subtitles language while a video is playing "froze" the image for an extremely small amount of time and subs started appearing.
In 0.87.5 and newer, switching the subtitle language while a video is playing has madVR display a black screen (!), then the image comes back with the newly selected subs.
From the changelog between 0.87.4 and 0.87.5, I believe the change responsible for this behavior could be the following?
*exclusive > windowed switch now shows a black frame instead of an old one
Is it possible to revert this change or don't have it active when VSfilter is used?

Great! It seems perfect to me now. Thanks.

For sure. I thought it was a madVR problem since it doesn't happen with other renders but madVR. Sorry.

That worked! So simple yet I overlooked it. Especially so as I had to do a similar thing to disable ffdshow interlacing (set it to "Bypass")

Unfortunately I have hosed ffdshow by updating to the latest 'tryout' figuring it might help. Going back to the previous build left me with issues concerning frame rate (30fps produces a hung image yet status (and audio) tells me it's playing..oh well..something to do Thanks again

Edit: Back in the saddle..yippie!

to madshi: another parallel random number implementation. I know, you've already found one and I don't know how this will perform or if it evenapplicable, just posting it here for info.

That doesn't look like it will give a uniform random number at all, especially when s_uRandSeed is small, and when s_uRandSeed is too large s_uRand won't have enough significant bits. As far as I know the random number generator that MadVR uses is faster and more reliable.

Hello, I have a problem with the full screen mode of madvr.
The default settings deactivate AERO in Windows 7 and my TV say that:

If I deactivate these settings in madVR, I don't get the problem.


I use madVR plugin of MeediOS.
Thank you for this best player. I use it every day

So, regarding my frame drop issues, I have grave news.

I swapped my PSU/motherboard/CPU/RAM and that made no difference. A friend just told me that he got himself a shiny new 780 Ti (so same GPU as mine but the card is from a different manufacturer) so I jumped on the opportunity and asked him to test for this problem. Turns out he had just installed Windows 8 so he had a clean, fresh system to do the testing.

He has *exactly* the same issue, namely frame drops every 10-30 minutes or so (with latest NVidia drivers, madVR defaults except smooth motion on).

This tends to indicate that every single 780 Ti out there has this frame drop problem. IF YOU ARE USING A 780 TI WITH MADVR, PLEASE MAKE YOURSELF KNOWN. Your input would be highly valuable.

This clearly smells like a pure driver issue that has not been fixed by NVidia yet and is affecting most if not all 780 Ti users. Tomorrow I'm going to dig in further and test every single NVidia driver version since the 780 Ti came out (331.93). I highly doubt this will reveal anything since I've already thoroughly tested 321.10 and it has the exact same issue, but one never knows. Does anyone know what would be the most efficient way of reporting this to NVidia?

In addition, it would be interesting if people with closely related GPUs (such as 780, 770, Titan etc.) could comment on whether they are able to achieve long zero-frame-drop playback (as shown in the stats) with madVR and smooth motion on.

I couldn't find the answer to this anywhere...does Nvidia's edge enhancement feature work with madVR. From what I did as a quick test it didn't. Once I switched to EVR it did. Is this a known thing. Sorry if the question is silly.

It does not. madVR intentionally by-passes all GPU processing algorithms.

I will need to retest with the newest madVR but I have used madVR + smooth motion on my Titan for nearly a year now. I usually see 0 frame drops and repeats even after a long movie.

However, I have never been able to use smooth motion + fade detecting de-banding without reported frame drops. I always use debanding with both set to low to avoid fade detection.

madvr doesn't support 3d yet. and if i see this right your tv doesn't support 3d at 60 hz.

madvr doesn't disable aero with default settings.

proud titan owner here, mind you its vbios modded aka boost 2.0 crap disabled , at a healthy boost setting of 1175 mhz on the gpu and a 3500 mhz on the ram at a power boost of 1.21v, with performance set to adaptive in the driver profile so it dont have no dreaded sudden performance drops like the horrible boost 2.0 does wich messed up fps like all hell

so ive noticed dropped frames or stuttering while using NNEDI3 from 16 up to 64 for chroma upscaling but 0 frame drops or stuttering with jinc3ar for chroma upscaling and NNEDI3 image doubling set to 64 for luma doubling and quadruppling and 16 for chroma doubling and quadruppling all set to always enabled , with Error diffusion option 1 and debanding at low and fade in fade out at high and the source was a 1080p/30fps video but does the same on lesser content aka 720p/30 and so on , mind you this

was on the older working opencl drivers aka 314.22 , as the current ones dont support NNEDI3 at all and logically not image doubling as well, hope we can see some improvement in that opencl performance department with fixed drivers , still no news i suppose

Anyone know what API madVR uses to increase the clock resolution? That is, decrease the timer interval from 1.000 ms to 0.500 ms.

I should have tested again before posting, I see no dropped frames even with smooth motion and debanding with fade detection.

edit: madVR v87.7, NNEDI3 64 neuron chroma, Jinc3 AR image, no doubling, smooth motion on, debanding low/high, ED2, no trade quality for performance. 1080p24 (bluray) -> 2560x1440 @ 75 Hz. Nvidia drivers 327.23
