OK, thanks for the hint.
The strange thing is, when I switch to EVR CP I get much smoother playment, so I'm wondering if it's because MadVR doesn't handle 24P well?

I think Beliyaal was trying to use Reclock in bit-perfect mode over his EVR CP(but Reclock was hiccuping from time to time from what I read)...I never tried either 24Hz playback or his EVR CP, but getting butter smooth video playback w/o Reclock is illusional IMHO(except if madshi strikes back! )

That explains, the old version of MPC-HC which doesn't have Sync render works fine for me.

greetings,

could anyone let me know if there is a known issue with madvr and directx 11? I recently installed a new game, which I believe updated my directx version. up to that point, madvr was working seamlessly. I found someone with a similar issue here (w/o any resolution).

In mpc and zoom player (or in graphstudio), the graph will connect, but the file will not play. until the program stops responding.

I'd sincerely appreciate any suggestions on how to troubleshoot this - i'm really missing the awesome madvr pq.

-jeff

Seriously, can we at least lock the guy out of this thread?

As far as xvYCC goes, now thats very interesting, it can only work on windows 7 and you'll need a hdmi 1.3 videocard.
What it does is increase the number of colors available within the existing rec709 limits, suddonly instead of 255 reds you have 40xx reds, which could result in a much more realistic picture.
madVR could use this to not only actually display very accurate video but maybe even dither the existing values to look even more realistic phycovisually(at the cost of pure mathematical accuracy ofcourse).
Very cool, man... thanks for the info.

I did go ahead and calibrate to a wide-gamut, and while my custom LUT brought everything within a reasonable accuracy, it offered no visual improvements and even seemed to introduce a touch of banding. Definitely seems that, if you can enable a standard gamut on your display, just stick with that.

Ah, but I'm excited to hear that xvYCC actually could improve things. My whole display chain is xvYCC, but, like a previous poster mentioned, I'd been baffled as to how to enable it. Good to know that it's solely a DirectX feature. Also, I imagine Deep Color would be similarly beneficial...? Do any current renderers take advantage of this stuff?

I am using a 7300LE in my office. Maybe it is a bit "low-end", but still shows the problem.

What resolution and how much video ram do you have? Use GPU-z 0.3.8 to check how much is actually being used. If you are trying to play a resolution that requires more video ram than you have, then there will be major lag.
704x480@30fps -> 853x480
Memory Used:
33M (w/o 3dlut) 153M(w/ 3dlut)

It does that, but what is the effect/problem/issue?
Video turns black before showing next frame.

It might appear/be that way because there is a 4 frame queue/buffer of some sort.
Why is madVR doing this? There is no such problem with other renderers. It may also bring A/V async.

Try use GPU-z 0.3.8 to find out how taxing each scaling algorithm is on your GPU core and GPU RAM/bandwidth.
I tried every algorithm. Only bilinear gives smooth playback. Well, even Overlay Mixer gives bilinear scaling.

Was the problem the black flicker or something else?

Video turns/flickers black and the video keeps on playing?

I'm pretty sure most Video Renderers have a render queue.

It *sounds* like that card is not fast enough to renderer the 30 or so fps while doing the processing for image scaling. If your card is not fast enough, then perhaps MadVR might not be an appropriate video renderer for your setup.

What I think could be possible bottlenecks: CPU usage, GPU Core usage, GPU RAM speed/usage...

My 9600M GT does around 10% for no scaling, 40% for 540p-> 480p, 30% for 540p->720p on MadVR's default settings. It is smooth like.. smooth.

Has anyone tried to use MadVR with new MPC-HC release with sync renderer?
The movie playback becomes laggy, I'm wondering the new release might break something in MadVR

After how long? What should I be looking for? I'm going to try MPC-HC 1557 32-bit right now..

edit: 1557 with MadVR appears to be the same for me... compared to 1281 ^^;

From the very beginning of the movie, and I can see judder all the time during the movie. The funny things is, when I turn on info, I can see there is NO frame lost/delayed......
Please give a try and let me know the result. It's more noticable when I play 24P on 23.976HZ device

My laptop only does 62Hz.

Try use ReClock.

Short story shorter, it says 60Hz, but ReClock picks it up as 61.8Hz and adjusts the video framerate so the refresh rate can be divided cleanish-ly by the number of frames per second of the video. 23.976FPS -> 24.8FPS

OK, if you use ReClock everything should be smooth.
I just don't like the idea to do audio decoding in order to make ReClock work.
My problem is, I want smooth 24P playback on 23.976HZ monitor.

since the material is 24p, can you change the refresh rate of the monitor to be a multiplier of the framerate (24, 48, 72, 120hz)?

For 24P the FPS is 23.976 (24/1.0001) which matches my refresh rate 23.976HZ, and I assume the playback should be smooth at least during the most time of the playback, however it's not the case with MadVR and the new MPC-HC.

So, if you revert back to an older MPC-HC the judder goes away?

Not tried yet, but I remember before I upgrade everything works fine. BTW, I also upgrade my graphics driver to 9.12, it could also be the driver issue.

Everything works fine on my desktop computer. I installed the same software versions (Win7 x76, MPC-HC, FFDShow, madVR) on my notebook (T6250, 8600M GT with forceware 195.62) but I cannot open any movies with madVR.
MPC-HC works well with EVR but it can't to open any files with madVR. (I tried to disable every possible madVR features but MPC-HC always crashes during file openings.) It shows a gray screen and one of the CPU cores is fully loaded but nothing happens. (I tried to wait some minutes). Nothing happens until I click somewhere on the MPC-HC window and Windows ask me about what should it do with this... Any ideas?
