Topic: madVR and SVP

I m going to give SVP another try because I hate the motion stutter on my JVC RS-25 projector. I installed everything I need and it works almost perfect exept for madVR in combination with SVP:

My projector supports 1080P23, 1080P24, 1080P50 and 1080P60. I ve set my desktop resolution in my NVIDIA control panel to 1920x1080@60 and SVP to frame rate to screens refresh rate. The problem is that I get a lot of dropped frames in madVR (one dropped frame every 2 minutes reported my madVR). I can understand this (I think) because madVR needs an exact match of the fps of the content that is playing (or a double of that I think). So without SVP i set my NVIDIA control panel to EXACTLY 1920x1080@23,976 (when running a Blu-Ray movie) and I get 1-4 dropped frames during a 2 hour movie which is great. When using SVP it of course has no sense to use it without setting my NVIDIA output to 60Hz. Will I not be able to use madVR and SVP?

Re: madVR and SVP

While I think that one dropped frame of 2*60*60=7200 is acceptable for 99.9999% of users wink you still got two options:
1. ReClock, or
2. Check "Frame blending to screen refresh rate" option in profile

MAG79, please correct me if I'm wrong  hmm

You are right cool

Re: madVR and SVP

Chainik
what do you mean exactly? I get one very noticable 'hickup' (dropped frame) every two minutes during a movie so that s far from ideal if you ask me.

ReClock is no option for me because I need digital output (for my D-Box system).
What does the frame blending option do exactly?

It does ConvertFps().

It adds ConvertFps() to the end of processing chain to convert from 23.976*5/2 to the exact measured refresh rate of the screen.

BTW, I hope the projector is one and only active screen in Windows? Or at least the primary one.

my projector is the primary screen.
Checking the frame blending option tops out my cpu usage to 95-98% which of course causes troubles. Do I leave the setting 'framerate change' on 'to screen refresh rate'?

OK, new plan big_smile
Open text file %appdata%\SVP\Ini\SVPMgr.ini and somewhere near 40th line change "maxden" to, for example, 2000 and "FPSDifference" to 0.02.
Restart SVP.

Then after opening video check the AVS script used. It should contain some big numbers in "multinum" and "multiden", not the usual 5 and 2.
And finally take a look at the file %appdata%\SVP\Ini\MediaInfo.ini:
- "FPS" - source video frame rate
- "num", "den"
- "Fres" = FPS*num/den
- "MonFreqD3D" - measured screen frame rate

What do you mean with 'check the AVS script used'?

Re: madVR and SVP

"show" - "avs script from last play"

yeah I know that current English translations're just awful  big_smile

And I don t have a Mediainfo.ini file in my Ini folder sad

It just can't be.
Are you sure you look into "C:\Users\sander\AppData\Roaming\SVP\Ini", NOT "C:\Program Files (x86)\SVP\Ini"?
And  SVPMgr.ini should be edited there too, not in "Program files".

To avoid mistakes use SVP Manager system tray menu: Show - Hidden Settings (in Expert Interface)

It opens right SVPMgr.ini file wink

Re: madVR and SVP

Thxz. I will try again tonight. but what will it actually do? and do i keep the last blending checkbox enabled and set svp to 'to screen refresh rate'?

Re: madVR and SVP

THX-UltraII
last blending checkbox enabled - nope
set svp to 'to screen refresh rate' - yep

what will it actually do?

SVP will choose more precise interpolation rate.

Re: madVR and SVP

Cool.
So frame rate after SVP is 60.022 and your screen frame rate is 60.002.
What's the number of dropped frames now?

  • Thanks: 8

Re: madVR and SVP

Chainik
I still get dropped frames but I think I know the problem:
The input frame rate for madVR needs to be EXACTLY the same as the screen frame rate that my NVIDIA outputs. I get 0 (max 3!) dropped frames whne playing a BR movie (23,976 material) with NVIDIA set at 1920x1080@23,976 (custom profile).

When I want to use SVP I (of course) have to set my NVIDIA output to 1920x1080@60,000Hz. This results in 60.022 which is 'send to' madVR but NVIDIA gets 60,002. This is a difference of 0,020. This seems not much but it s too much when doing bitstreaming like me.
Is there a way to correspond these two values EXACTLY to each other maybe?

for your info, I get the following in ediaInfo.ini with the standard maxden 20 and FPSdifference 0.12 setting:

Re: madVR and SVP

THX-UltraII

OK, let's set "FPSDifference" to 0.001 in SVPMgr.ini

  • Thanks: 8

Re: madVR and SVP

Chainik
just tried 0.00 and now Fres shows 60,001 and MonFreqD3D 60,002 so this seems almost perfect. Can 0,00 not be used and should I give 0.001 a try tonight? What does the value do exactly?

0.00 gives me almost no drops. Tried 30 minutes of playback and only got 3 drops (and where not noticable as hick-up in the picture by the way).

and what does the setting 'maxden' exactly do when changing this from 20 to 2000? Tried 0.00 with 2000 and with that setting I got the 30 minutes-3 drops result (which seems pretty good). Also tried 0.00 with the standard 20 maxden value and got a lot of (not detectable by the eye) dropped frames. So it seems indeed that increasing maxden results in less dropped frames. But how will I know if I need 200, 500, 1000, 2000 etc? And why not use eg. 25000000 to make sure there will be no dropped frames?

Re: madVR and SVP

THX-UltraII
what does the setting 'maxden' exactly do

It's the maximum allowed denominator value in 

<resulting frame rate> = <source frame rate> * num / den

0.00 gives me almost no drops

Good for you wink

There's a little problem with big numbers in "num" and "den" - you've go no original frames in output sequence which means more visible artifacts, while with 5/2 every 5th frame is original.

But we've got your point wink
