madVR - high quality video renderer (GPU assisted)

[iSeries]

@ robpdotcom & iaTa:

In CCC if you have added 1080p24 to the display manager and then choose 23hz for your refresh rate, when you click apply it will show 24hz - BUT it is actually 23.976hz. At least that's how it works for me.

Hi !

For some reason madvr does not go to automatic exclusive mode anymore even if no GUI is shown. I have attached the logfile. Can you see anything in there ? This is with ZoomPlayer on ATI 4770 with Powerstrip, latest 10.7 drivers, Windows 7 x64 on second monitor.

Thanks,
Alex

Thanks for that...this fix "kind of" worked. When I am in windowed mode I can see madVR outputting 23.977, but when I am in exclusive mode, it jumps to 24.001. I assume this is because madVR is trying to match my "display" refresh, which I believe my Onkyo is reporting as 24.001. Any other thoughts?


Thanks,
Santino

A quick update. I was able to come up with a workaround, but it is not ideal. I set up a profile in CCC and set up a hot key to call the profile. Once in exclusive mode I can call that profile and it will change the output to 23.976, but if I go out of exclusive and back, the renderer goes back to 24.001. For now I think I can setup event ghost to do it automatically, but a "force 24p" would be a nice added feature "hint hint".

Did you read the post I mentioned above?
If not, here's the important part:

If you are switching form 23 to 24 or vice versa, it won't switch. You need to switch to something completely different first (like 59 or 60) and then back to 24 (or 23). Same goes for 29/30 and 59/60.

[vladd below points out that it's a CCC problem, you can still change at will with the Windows interface (see his post if you don't know how).]

I did read that, and it does work, but when madVR goes to exclusive mode, it changes the output to 24.001. My desktop is now set to 23.976.

Please disregard. I installed SAF for Media portal, and now magically exclusive mode is now at 23.976. Go figure.

Thanks,

so using ffdshow's deinterlacing filters and dscaler together, is this ok? do I have to disable the inverse telecine mode of dscaler then?

You can forget the DScaler's internal deinterlacing (leave it as auto)

Activate FFDshow's deinterlacing, Yadif preferably, when watching 29.97fps content.

Is it a good idea to upscale in ffdshow via AviSynth tab by doing Spline64Resize(1920,x) (where x = 1920/Aspect Ratio of source video) and then send it to the renderer?

[namaiki]

No, madVR will upscale using a resizer of your choice, including Spline64 if you wish it.

Maybe, if your GPU not fast enough for upscaling math in this case. But it seems like madVR uses better math than ffdshow or that avisynth script.

madshi,

I'm sure now that 0.27 cause "black screen" & freeze while 0.26 doesn't. Note that it happened more but not exclusive to my dual monitor setup. On the other hand, I think the BSOD is not because of madVR.

This is happening for me as well now with a single monitor setup. Randomly I get a black screen & freeze when starting videos.

Still have interlaced videos constantly dropping frames in 0.27 as well. Going back to 0.26 for now.

[Razoola]

I always get the black screen first time I try with 027. It seems to only happen once and hangs the player, I need task manager to end process, then every time after that its fine until I reboot the machine then it will happen again. This situation is very simular to what happened originally with many nvidia card owners with madVR not working at all due to some slow scan line reporting issue I think madshi said it was.

I also get the random dropped frames with 027 what were not happening at all before and have gone back to previous version.

[SantinoSan]

Does madVR output RGB signals? I am trying to set this up so that there is no additional processing done by my video card, so I guess my question is what should my video card output be set to in order to save all the PQ imporvements from madVR? My options are RGB full, RGB limited, 4:2:2, and 4:4:4.

Thanks,
Santino

I also seem to get random dropped(not delayed) frames 10/20 secs after seeking from time to time, this didn't occur w/ 0.26 AFAIK.

But seamless playback is very smooth in PotPlayer when seeking between files w/ different AR, it used to stutter a bit in older versions.

"RGB full" so your graphic card outputs unmolested 0-255 RGB

Thank you for that. I'll have to play around with the rest of the filters in the chain to get them set right. What should madVR be set at? I assume video levels to pass BTB and WTW...is this the case or should I have it set to PC levels?

Thanks,
SAntino

I'm sure there must be something simple I am overlooking here... I've installed MadVR but MPC still shows it as a greyed-out option. How do I get it enabled?

my setup:
Win 7 64bit
madvr v0.27 installed via .bat with admin rights
Media Player Classic HomeCinema (x86/x64), svn 2345 (i've tried the zip build and the installer both, x86 version only)
ATI HD4890 w/ 10.7 drivers

the levels options could be clearer, as they work the opposite way from HR.

the first option means: untouched levels, and the second: TV>PC conversion.

Try installing it in another directory, when you click the batch file it should come up with a window saying The DirectShow filter "madVR.ax" was registered successfully. It should be usable straight away in MPC.

Maybe also try uninstall before re-installing madVR. And, make sure not to delete or move the installation directory.

After you have installed it make sure you do not delete the directoy where you ran the bat file as this becomes the installed directory. I have heard of people deleting the directory after thinking the install bat moves filles somewhere else.
