Hi everyone,

I switched from MadVr to EVR custom for a few test and went back to MadVR.
But since that time, the lower third of my videos are pitch black, just as if a black banner was added above the video.

Is there a solution to this problem ?

Thanks !

With nVidia drivers 275.xx I could get smooth playback (DX9 - GTX 275 and Win 7 64) by using ALL of the options to prevent glitches.
With 280.xx, it doesn't work anymore, so I have to use Windowed mode (it is perfectly smooth that way). Messing around with the options I can reduce the glitches but I still get them pretty often and playback isn't smooth.

I do miss exclusive mode because of the seek bar and the fact that nothing could possibly disturb the playback. Rendering/presentation times were far better too, but I'm not sure it makes much difference in my case (they are not 'bad' in windowed mode).

There is no P-state change in my case, my GPU is running at full speed 100% of the time.

Huh? 60p is awesome. We don't really even have widespread HD here, (or TV stations worth watching...). Hell, the cheap ass TV stations only just moved to 16:9.

madshi, a nit really, but should the sig for SettingsGetString in mvrInterfaces.h be:

Code:
STDMETHOD_(BOOL, SettingsGetString )(LPCWSTR path, LPCWSTR* value, int* bufLenInChars) = 0;

He expects the caller to allocate the string buffer, so it makes sense as it is.

Yup, I just got it, sorry for the temporary detour...

A bunch of people with nvidia graphics here have this issue. Don't use RGB32 input.

Hi!

I use madVR together with Zoom Player 8, and ZP has a feature to display seek position popup hint over control bar (control bar is called by pressing "space"). ZP can output this interface elements in madVR fullscreen exclusive mode.

There is a hang of the player if I call control bar and move mouse cursor over control bar for some time in fullscreen exclusive mode: video freezes, sound keeps playing, the player is not responding.

Don't worry,it's going to be ok.
Just open the OSD,play any MPEG2 source (Dvd,1080i) with the Dscaler filter and tell us what does the fourth line indicate.
Should be "MPEG2,8 bit,4:2:0 ->[This is the interesting part]"

720p/60 rocks for sports, FWIW.

Dramas are telecined from 24p to 60p so decimate by 2 then by 5 to get back to 24p. Not aware of a reliable way to do this on the PC in real time.

Funny you mention sports, since upscaling the 720p60 US Open tennis broadcasts to 1080p60 is exactly what I'm experiencing the most difficulties with. 1080i60 is even better imo, with good deinterlacing (which is my main reason for considering a new NVIDIA GPU, to get HW deinterlacing along with MadVR).

I would think that an ATI 5750 would handle 720p60 -> 1080p60...

My IVTC filter can do this. Or if you want something stable and maintained, you can just use ffdshow with Avisynth (drop every two frames and then decimate using e.g. TIVTC). Modern PCs have more than enough horsepower to pull this in realtime no problem. It's much faster than doing IVTC on 1080i30.

Mine can, with EVR Custom or madVR in exclusive mode - but only in exclusive mode.

I've never been able to get it to work with 720p60. It always just plays at the original framerate. I know I need to disable soft telecine detection in the decoder options, but is there another setting that could have an effect?

It's also possible that the content I've tried it with wasn't actually telecined... mostly with sit-coms on ABC.

I really need to learn to use Avisynth, if for no other reason than IVTC'ing recorded TV.

its "MPEG2, 8 bit, 4:2:0 -> YV12, 8 bit, 4:2:0" (dscaler can do YV12 and YUV)

Very cool,Thunderbolt8.Thanks again !
I'm going to test Dscaler next week.Wonder why Madshi never spoke about it more emphatically because with this one we have the perfect 4:2:0 output set:
MPEG2-> Dscaler
AVC-> Coreavc 2.0
VC-1-> MS decoder

To be noted that the latest XVID decoder outputs...4:2:2.Sigh.

The only advantage DScaler has is for telecined DVDs. The only reason to use it would be for NTSC DVDs that need 29.97 -> 24p conversion. If you never watch that kind of content, could as well use a faster and more up-to-date decoder.
