What I'd really like to know is if we can have nnedi performing it's 2x enlargement and then it being further upscaled with Jinc/Lanczos etc.. that would be something. Something quite taxing for the GPU I would guess too.. Time to move into mid range graphics performance. Last edited by ryrynz; 22nd January 2014 at 02:48. |

implementation of "display <refresh rate>" in CTRL-J stats
How is hte actual display refresh rate measured as reported at the top of the CTRL-J stats box? Is this a directx feature, or is it something more portable?
Forgive me if this has been asked before, but it didn't show up in preliminary googlings. |

From what I've seen image experts would class the nnedi upscale to be of higher overall quality, performing a first stage upscale with nnedi in this case should yield improved image quality (colors, aliasing etc)
Perhaps Madshi could show us some screenshots for comparison? Last edited by ryrynz; 22nd January 2014 at 10:04. |

If my memory is correct, it was first introduced on XBR2 / KDL-X2000... one of Bravia PRO 1.0 functions. Last edited by pie1394; 22nd January 2014 at 07:21. |

It's custom code based on polling the current GPU vsync scanline position once every millisecond and doing some math on that, plus some extra code which "connects" these measurements over long periods of time, so that the refresh rate estimate gets more exact over time. |

Its the first time that I encounter this NNEDI resizer, but after a bit of googling I can conclude: It is one of the best looking realtime upscalers I have ever seen. Moreover, there is no hardware player that uses this method, so we get absolutely the best PQ over any Blu-Ray/DVD Player. Again, thank you madshi for making our HTPC experience much much better.

Ouh, very impressive indeed
I thought NNEDI was only a deinterlacer, but wrong I was. Will it run on the GPU or CPU? Will it be a resource hog? I've got a bunch of 360x288 videos that do look nasty when upscaled to 1080p, I'm ready to expect the unexpected |

Now that I just upgraded my laptop to a discrete gpu again, I'm looking forward to this weekend. |

Yes, finally profiles support (at the very top of my wish list, since the start of madVR), thanks a lot madshi!
I´m wondering though, by looking at your teaser screenshot, is there a reason why it only shows 24fps and 60fps for SD and HD respectively, but no 25fps, 29,970fps, 30fps and 50fps options? |

A little early to tell but I guess that the new "Image Doubling" algorithm is more optimized than NNEDI3 (maybe even GPU optimized), hence faster.
This function will be very useful in the near future when 4K monitors arrive to scale HD to 4K, hope we'll enough juice by then. I have experimented with NNEDI3 (in Avisynth) and a 720x480 24fps DVD video, and found it was using a lot of power from a i7 3770K 4.5GHz with x2 factor. With x4 its not usable because its too slow and unable to render 24fps each second, MadVR buffers where empty (maybe I was doing something wrong?). Indeed NNEDI3 eliminates aliasing almost completely. We'll have to wait and see how MadVR's "Image Doubling" behaves and how much power it takes. |

By the look of it, It'll be highly customizable. Last edited by James Freeman; 22nd January 2014 at 13:22. |
