As other people commented, they look close enough at least this doesn't explain the amount of dropped frames.
What happens if in both players, instead of using the internal audio renderers, you manually select the DirectSound audio device (Topping?) ? Do the frame drops stop then?
I know this is not what you want, but it's to find out if the audio renderer is the cause.

thank you so much. Everything works as you thought.

I changed the audio renderer:



now MHC-BE is perfect:


I never thought madVR would get swayed by audio. I'm afraid there are no solutions. I would prefer to select "MPC AUDIO RENDERER" but it is not possible.

MPC-HC with its internal audio Renderer is no problem. MPC-BE only

Thanks everyone for the help, much appreciated.

You should post all relevant info regarding this issue over in the MPC-BE forum so the audio renderer can be improved to prevent this from happening.
Wouldn't hurt to try the releases here download the standalone filters packages (x64)
and register it in the system it will then come up as another audio output that you can select in the drop down, then test and see if you can find a version that works without dropping frames.

Hello, I've been using lav filters and Madvr for 3d for 4 or 5 years now with no issues. About a week ago, it stopped working. Anyone know anything about this? I've reinstalled madvr and lav and still it doesn't work, when it does flip into 3d, its like the 3d is in slow motion. I thought it might be my hdmi to ethernet converters screwing something up so I connected the computer to my spare projector with straight HDMI and it did the same thing. I thought it was one specific file as we had literally watched 3d the day before and then realized it was all of them. Anyone have any ideas? I'm thinking a windows 10 update maybe or something broke it. Its a windows 10 machine with I3 processor Skylake with internal intel graphics.

Impossible to say without more information, things do not break like that by themselves.
Under "View update history" in Windows Update settings, you can see exactly what date Windows installed updates, and also uninstall them. Maybe check that. Maybe it installed a new graphics driver?

Tried tonight after days of troubleshooting, reverted to previous version of windows and it works perfectly again, hopefully this helps someone.

[el Filou]

When you say "previous version", was it a monthly ("quality") update, or a full new release ("feature update")? Can you give the two versions before/after the update?

I solved the problem!!!!! In the MPC Audio Renderer settings it was enough to change the DEVICE BUFFER from 50 ms to DEFAULT!
Now I don't lose frames anymore and madVR's OSD is perfect!
Thanks for your help!

Cool thanks for letting us know.

Regarding the screenshot of madVR info - how did you manage to almost set / sync display Hz to video Hz ?

Setting the TV to 23 or 24Hz would that suffice?
Appreciated

[Klaus1189]

23Hz is for 23.976Hz
24Hz is for 24.000Hz

Hi,
I have just downloaded beta 120, is there a way to copy HDR settings for different devices. I want to use the same settings, changing only DPL values. I don't know how to do that. Hopefully somebody can help me, thanks a lot to all of you

[VBB]

@webbo - That's AMD You won't get nearly as close with Nvidia, but it's not too bad right now (about a drop/repeat every 1.07 hours).

Hello! It is madVR that changes the TV refresh rate adapting it to the native one of the movie.

I see a GTX 3050 could be coming. Would 4GB of RAM be enough for proper madVR use? I think GPU power should be plenty enough (but correct me if I'm wrong).

[huhn]

4 GB should be fine with current algorithms and UHD output.

Is madVR or the video driver responsible for the depth information in 1080p 3D frame packed output? I found at least one of my 3D BD's when ripped to .mkv and played back from the PC has intermittent odd depth shifts (like the image will jump forward or backward a bit mid scene). The jumps aren't there when the 3D BD is played from a Blu-ray player.

Hi everyone.

So I got a new LG CX OLED and I have this issue with subtitles using MPC-HC with MadVR :
- with the internal subtitle renderer, no problem with .ass subtitles (I can change their look) but in HDR, subtitles stay bright white whatever my changes
- with xySubFilter, .ass subtitles are out of whack (generally looking extemely small) but I can change the color of HDR subtitles
- with DirectVOBsub, any subtitle in SDR is easy to set up as I want, but then MPC-HC doesn't output in HDR (I guess since DirectVOBsub is not part pf MadVR)

Does anyone know the settings to be able to set the color of subtitles to light gray and with whatever font and size I want, whatever the resolution of the content and whether it is SDR or HDR?

Thanks

[chros]

Do you have issue with ass subs only? If so, upload it somwhwere.

How does madvr detect hdr and where does it get the essential information?
I want to render a not tone mapped 4k hdr stream from a capture card, but madvr does not detect the video stream as hdr. For matrix, primaries and color range it only does a "(best guess)" with bt.709 and limited. When looking at the pin info, there is only VIDEOINFOHEADER set, but no VIDEOINFOHEADER2 with DWCONTROLFLAGS.
Is it possible to inject this information upstream of madvr or force madvr to do a "best guess" with bt.2020?

I hope anybody has an idea. Thank you!

I was wondering if you ran into any favorable results in trying to figure this out. Ive been trying to accomplish this all month.
