MPC Video Renderer - interlaced hdtv content is jerky

[bobdig]

I just read that the MPC Video Renderer will be the default renderer on most systems.
I did an update to the K-Lite Codec Pack on my system and thankfully it isn't the default yet.

Now to my problem with it, interlaced hdtv content is jerky forever now on my system with the MPC Video Renderer. No problems with the other renderers.

Upload short sample, show MPC VR options and full screen screenshot with statistics.

[bobdig]

and full screen screenshot with statistics.

@Aleksoid1978 Where to find this option?

[bobdig]

@Aleksoid1978 Anyways, so here is a sample, have fun with it. ;)
Jerky might be a little harsh, but whatever EVR-custom uses is looking much smoother to me.

You can press Ctrl+J to toggle statistics overlay.

You can press Ctrl+J to toggle statistics overlay.

Thank you. So I updated the link above. And what I already can see in the statistics is, that it is saying Presentation:Discard for the MPC-VR one.

[clsid2]

That is normal. It isn't dropping frames if you think that.

[bobdig]

That is normal. It isn't dropping frames if you think that.

No, thought about deinterlacing.
Ok and with that dropping half frames. ;)

[Aleksoid1978]

For me is normal, smooth playback.

1. Try select Swap effect - Flip.
2. Try using DX11 - it's support using LAV Video DX11 Native decoder.
3. Try using fullscreen exclusive.

@Aleksoid1978 So tried this morning again and first I couldn't see the difference myself... but it is still somewhat dark outside.
I then cranked up the brightness on my monitor to a more normal level for midday usage and the much better smoothness for the EVR was visible again. Changing any of the mentioned options did nothing for me. So maybe I am more sensitive to high frame rate or smoothness in general? Although It is only with interlaced material.

@clsid2 Have you tried it? I will stick to the others but I guess I always will be free to select the renderer I like most. For me it is the EVR, no fancy gimmicks I don't need, just works for me. MadVR is also smooth, although it is to complicated for my taste and knowledge. I also stick to the k-lite CP Standard defaults.

[clsid2]

I don't notice any difference. But my monitor is only 60Hz and yours is 144Hz.

I see in your statistics screenshot that the green line is "flatter" for EVRCP than MPCVR. So smoother. Here the graphs are similar (saw tooth pattern).

[bobdig]

@clsid2 So I changed the refresh rate of my monitor to 60Hz and the green line for MPC-VR changes too, now one smaller spike and then one bigger spike, for EVR it stays totally the same.

I then went into render settings for EVR and activated VSync. Now those lines look not so good anymore, but the video is still smoother, so I don't know, if this is really related. As a noob I would guess, that it is just another (in my opinion not so good) deinterlacer, which is used by MPC-VR.

[clsid2]

The deinterlacer should be the same afaik. Both use hardware deinterlacer from your GPU.

[bobdig]

Too bad that it is closed, it is not resolved.

[clsid2]

It is not a bug in MPC-HC, so there is nothing I can do.
