With anti-ringing I like bicubic better than softcubic. From what I remember, softcubic doesn't use the part of bicubic that "undoes" some of the blur but causes ringing. As madishi's anti-ringing works so well there is no reason to use softcubic now imo. Quote:
I hope it is a DDR5 one, if it uses DDR3 it is probably slower than the HD4000. It will not be a significant upgrade from the HD4000. It looks about the same performance. |

Depends on how much you're scaling by, and material.
If there are sharp chroma transitions, you're scaling like 360p or lower to 1080p or higher, differences will definitely be noticeable for some luma upscaling algorithms. Otherwise, to some extent, people are really sweating the small stuff, which may not really make much of a difference in practice. Or it could be next to invisible. IMHO softcubic is better for lower-quality material that may have artifacting and other problems already. You're blurring out problems as well as details. For higher-quality content, I'd take a sharper algorithm, both luma and chroma. I kind of like the chart as well as a general guideline, but I don't like ringing and would never use anything sharper than bicubic 75 on luma (and maybe not even that much) without anti-ringing. Depends on the material though, as always. I don't think any HD 6450 uses GDDR5. |

@trip_let
Personally I don't think using a blurry resize is the best way to PP low quality video but to each their own. I just watch the blocks and mosquito noise. It may be discontinued but: Radeon HD 6450 512MB 64-bit DDR5 But you are right, chances are adhara's is a DDR3 card. Last edited by Asmodian; 22nd February 2013 at 21:01. Reason: added @ |

Yes my Sapphire Radeon HD6450 (40$) is a 1GB DDR3. IMO best fore me is to wait for the new IGP (Hasewell GT3). I read it will be 3x more powerful than the HD4000. |

Of course. But with a properly working smooth motion FRC algorithm you should see neither judder nor ghosting compared to true 24fps@24Hz playback. Of course FRC isn't perfect, but it should achieve at least 95% of the motion smoothness of 24fps@24Hz without any visible ghosting during playback. Of course if you record the frames that madVR draws (e.g. with Fraps) you can see the blended frames and they look awful. But in motion they should not be visible - unless your GPU shows them for 2 vsyncs instead of 1. Quote:

Can I have a sample of that 25i content which doesn't look well for you? Quote:

It probably has more to do with how your display handles image persistence than its motion resolution though - you will probably only see it on LCDs with scanning backlights. Quote:

And if we get enough fine-grained control for madVR LUTs in the future, you can do some neat tricks with CRT for "infinite" contrast. |

madVR v0.86.1 released
http://madshi.net/madVR.zip Code:
* fixed: saving settings failed when madVR couldn't write to its own folder * fixed: sometimes old frames were flashing up when using smooth motion * fixed: seeking in exclusive mode could result in a freeze * fixed: high bitdepth content showed artifacts when using DXVA scaling * smooth motion FRC is now auto turned off for DVD menus * improved exclusive mode presentation timing with jittery audio clock a bit |

2 questions:
1. How do I fix the BTB (grey desktop) problem that the Intel intergrated Graphics 2000 has? 2. How can I make a 23,976Hz custom profile? The default 23Hz profile is 23,972 and I want to aim for 23,976XXX. When I choose Custom Resolutions I can only fill in round number and no numbers like 23,976, only 23/24/25 etc. |

[removed] Okay after I updated to 0.86.1 the bug disappeared, whatever it was causing it is gone now.
Also, could you take a look at this little fellow post. He seems to be having problems with exclusive mode off (windowed I believe) and when you see the youtube video he posted, it kinda reminds me of tearing but I'm not sure. Apparently he changed his monitor refresh rate to 24 hz to match the 24p video to eliminate judder but got that problem instead. Quote:
You also remembered me to put that in my signature to share with others, not many people are aware of that thing.

Will record a longer 60fps video and test that one too. Sample 1 still looks very unsmooth with FRC. I can't say for sure if maybe this has to be since I can't watch it in native 24Hz atm. Download: http://www22.zippyshare.com/v/7254850/file.html With sample 2, watch for the dust between the trees. It looks very nervous/flickering with FRC. Without not. imho clearly an unwanted side effect. Download: http://www67.zippyshare.com/v/94753150/file.html |

Same issue occurs on both Windows 7 & Windows 8. [Edit: Below are a few more with 119.88Hz for good measure] madVR TestPatternSource 23, 24, 59, 60 @ 119.88Hz Deinterlacing to 59.94fps @ 119.88Hz IVTC starting with 2:2 (29.97fps) and going to 3:2 (23.976fps) near the end @ 119.88Hz Last edited by cyberbeing; 22nd February 2013 at 23:13. |

Hello,
I've seen a few recommendations now to use ReClock with FRC. So what settings are needed to make ReClock compatible with FRC? Just slave the reference clock to audio and lock the speed at original? Thanks, ->g. |

@glc650
ReClock is fully compatible with FRC. The settings you suggest will turn off ReClock's audio clock corrections. Why would you want that? (The only benefit then over other audio renderers would be having WASAPI.) |
