The 2nd screenshot definitely looks too red.

Try resetting MPC-HC settings to default. Maybe the saturation slider got set too a non-neutral value?

I've tried to reset mpc-hc, unfortunately without change.
I forgot to mention that i have the same prob with mpc-be + madvr.

Thanks

Can you make a small sample which contains the 2nd screenshot (the one with the man lying on the floor)?

The sample can be *really* small. Just needs to contain the 2nd screenshot, so we can compare result on your vs my PC.

This looks like a bad user encode to me.

The h264 bitstream contains the field "colour_primaries = 8". Which according to the h264 spec means "Generic film (colour filters using Illuminant C)". And if you look into the madVR OSD (Ctrl+J), you'll see that madVR detects this properly and renders the video with the appropriate colors.

It's all the other video renderers which do it wrong, only madVR does it "correctly". madVR looks bad because the video bitstream probably contains wrong information.

Press Ctrl+Alt+Shift+P multiple times to switch to BT.709, that should work around the problem. Or add the text "primaries=bt.709" to the file name.
