"Bicubic" already is present.

We use cubic convolution with a = -0.5.
Code:
// bicubic #define filter_support (2.0) inline float filter(float x) { /* https://en.wikipedia.org/wiki/Bicubic_interpolation#Bicubic_convolution_algorithm */ #define a -0.5 if (x < 0.0) x = -x; if (x < 1.0) return ((a + 2.0) * x - (a + 3.0)) * x*x + 1; if (x < 2.0) return (((x - 5) * x + 8) * x - 4) * a; return 0.0; #undef a }

Ok, it would be nice to have local time on screen all of the time just like remaining time..
Exit out of mpc-be, then go back into mpc_be and start another movie, one has to turn local time back on again.. Whera as time remaning is there permanent.. |

ok it's just a -1.5.
i changed it and build it on my PC. i couldn't figure out how to add one more filter to the list and name it so i just change bicubic a to -1.5. screens: madVR bicubic 150: https://abload.de/img/madvrbicubic150rmjc8.png mpcVR bicubic 150: https://abload.de/img/mpcvrudjok.png source: http://vah.dy.fi/testcard/3840x2160.png my recommendation would be bicubic 60 (same as in mpc-be) and bicubic 150 downscale only so -0.6 and -1.5. another real world example: mpcVRbicubic50: https://abload.de/img/bicubic60n7kpj.png mpcVRbicubic150: https://abload.de/img/bicubic150fvkhe.png source: http://uhd-wallpapers.net/images/ven...canal_542.jpeg |

You are right - 150 is more "Sharper" then 50.

it rings a lot that's why it is only recommended for downscaling while sharp upscaling looks really bad.
of cause there is another one even better algorithm ssim: https://github.com/zachsaw/MPDN_Exte...SSimDownscaler but bicubic 150 should be good enough for most user. |

MPC Video Renderer v0.2.0.658.
tested it, really like it.. Only thing is that it does not support shaders? If i use teh MPC Video Renderer v0.2.0.658 and enable my deband shader it wont work.. is there a reason for that? THX.. |

If you have examples that show the difference between bilinear and bicubic/lanczos chroma upscaling, then I will ask you to provide it to us. MPC VR does not support external shaders.

chroma scaler had been check a countless time in the madVR but i can do you another test with it.
the biggest problem is nvidia right now there DXVA chroma scaler is moving the chroma which can results in a lot of aliasing. this has been tested with EVR and madVR. even a simple bicubic 60 should be far better. |

PS: I talked to users who install madVR, put up heavy settings, and then can’t answer the question "What did not suit you in the standard settings?". They just read one of the stupid instructions from the Internet.
