I'm running ROHQ with madVR (Jinc 3 taps with AR both on chroma and on image). I have problems with dropped frames for some DVDs when madVR activates deinterlacing. The average time then goes up from approx. 16 ms to 30 ms (14 ms deinterlacing). Automatically activate deinterlacing (if in doubt deactivate) is enabled by default in madVR. Why does deinterlacing kick in for some DVDs and not for others? Everything seems to work fine, when I disable automatically activate deinterlacing. Are those DVDs interlaced or not?

The stats above with deinterlacing are in fullscreen windowed mode which is default. Changing it to fullscreen overlay mode reduces the deinterlacing time to < 5 ms and everything is fine again. Any disadvantages with fullscreen overlay mode?

I have a NVIDIA GTX 650 OC card. Should use inverse telecine be enabled in the NVIDIA control panel/Adjust Video Image Settings/Deinterlacing or disabled? I have enabled use the video player settings instead of NVIDIA settings for all other settings.

Using the standard ROHQ settings, particularly with Hardware Acceleration enabled gives me poor results due to the settings that they use.

With an Nvidia card in my system, Hardware Acceleration seems to use LAV Video set to use CUVID decoding. This is bad for two reasons:
1. CUVID forces the graphics card into the highest power state at all times - my GTX 570 is more than fast enough to handle decoding and scaling in the medium power state.
2. CUVID seems to cause madVR to incorrectly detect progressive videos as being interlaced.

I am unsure about whether you need to have a separate LAV Filters install or not, but if you change Video Mode to Advanced - Custom, you should be able to add LAV Video as a decoder, and then configure it to use DXVA2 Copy-Back instead. Don't touch any of the other settings, and make sure you are using Copy-Back rather than Native.

Deinterlacing works a lot better for me with DXVA2 Copy-Back than CUVID, and it allows the card to drop down to the medium power state if it doesn't need the card to run at full speed.


I also never play back any video-type DVDs on my system - only films. If that is the same for you, in the madVR settings, you might want to disable automatic source type detection and force film mode. This stopped a number of problematic titles from either dropping frames, or losing resolution from being detected as video content by mistake.

This is often caused by improperly detecting the video type, or losing cadence lock in my experience.

Some DVDs are really just progressive video and don't require deinterlacing.

Fullscreen Overlay should be faster, but you can't take screenshots with it running via the PrtScn key, and I found that transparent elements of the MC18 UI don't look good with it. Otherwise, you should be fine using it.

Fullscreen Exclusive should perform even better, but doesn't play nicely with the MC18 UI, because any time the MC18 UI is brought up, it kicks you back to Windowed mode.

Thank you!

I don't use Hardware video decoding acceleration. My i7 3770S is fast enough, I think.

I will play around with force film mode.
