Thanks! Quote:
Well, you could still switch scaling to "Bilinear", that is done by the graphics card "for free". Doing that might push you under 40ms. But of course then you have lost many advantages of madVR. So I'd say with your graphics card using madVR does not really make that much sense, unless you want to use madVR for gamut&gamma correction... Quote:

But is it really visible inside of text lacking movie scenes? I never saw it. On the other hand if you look at these shots from the same movie you can see much less aliasing on the inner side of the mirror (very annoying in moving scenes), but no additional ringing. Lanczos2: Lanczos10: And if we analyze the picture a bit closer with the h-sweep pattern and a waveform analyzer: Lanczos2: Lanczos10: It is obvious that the higher frequencies are transported better with Lanczos10 and that this algorithm acts as a better low pass, because beats (aliasing) gets less. The h-sweep looks cleaner and very slightly more detail is visible. Of course if you look at the sides of the h-sweep (hard edges, square wave) there is additional ringing introduced by the scaling algorithm. But these areas content high spatial frequencies which movies *usually* don't (or as I learned only rarely), because of the necessary low pass filtering. Anyway, you are right. Because everything is just a big compromise it is just a matter of preference. Less aliasing and more detail (Lanczos8) or less ringing (e.g. Catmull-Rom).

I see two or rather three circles (light, dark, light) around that ear ring with Lanczos8. (This is still My Fair Lady, the scene directly after the intro.) Have you tried SoftCubic50? Yeah, it's not as sharp as Lanczos, but it's just as aliasing free as Lanczos (I think) and adds no ringing at all. |

Hi mashi, yes i tried lowering the scaling filter and was able to get a lower GPU time, now its fully usable!
I Don't have to use point, the next one up works too! Trade quality for speed options lower 10ms, however the different scalers can make a difference of up to 40ms. I know my card is not very fast, but it has no problems with Fallout3 @ 1920x1080, with most settings at low |

Madshi
The tearing on the secondary monitor of my HD2600XT has been fixed by Version 0.4 (or 0.3...I was too slow for that one). I have to pause/unpause to get smooth playback without jitter (similar to Haali, but not so smooth for now), but it's good, really good. Thank you very much! My stats: display 95.90361 Hz (3s) movie 23.976 (says source filter) frame queue 16/16 movie resolution 1920,1080 target rectangle 0,0,1920,1080 vsync interval 10.43ms movie frame interval 41.71ms avrg gpu rendering time 14.08ms max gpu rendering time 20.59ms avrg present wait time 4.35ms Is everything ok with the numbers? As (nearly) always, I am doing no scaling, watching 1920x1080p 23.976fps at 1920x1080 interlaced at 95.904hz on a CRT monitor/projector.

anyway, I've tried numerous mobos/graphic cards...never had any tearing on XP or Vista. a little while ago, a guy posted all his BIOS settings on the Reclock forum....I gave him a few hints and the tearing he had in HR apparently went away http://forum.slysoft.com/showpost.ph...8&postcount=18 that'd be pretty cool to get perfect colorimetry in mVR, hope you can work it out!

Btw in terms of bandwidth Catmull-Rom looks like Lanczos3, but with a bit less of ringing and a bit more of aliasing. I still prefer Lanczos8 when watching DVD's. On a big screen any aliasing or lack of detail becomes clearly visible. In my eyes the inherent ringing of most DVD's covers the little additional ringing caused by the scaling algorithm. Just my two cents. |

don't u agree that spline36 is prefered for down or upscaling? this thread seems to convey this idea(and so do my eyes in ffdshow) : http://forum.doom9.org/showthread.ph...30#post1266030 Quote:

If lanczos where ringing free would it be the best scaler? |

Thing is to achieve somehow a "soft" reinitialisation of the renderer in the event of posting to a different monitor. Even HR has a noticable lag when you move the window, where video disappears for a second or so. Same with VMR9. madVR is the only one amongst usable renderers which doesn't do this and this is a definate bonus. Please note that there's also a partial case, when half of the video is shown on one monitor, half on another In such cases, haali and VMR9 still output as normal and call for reinitialisation when about 2/3 of the video enters to a different monitor.

Looks good to me. Your graphics card seems to be plenty fast. Quote:
You may want to search for threads started by me... Quote:
(1) Use a good media player, e.g. MPC HC or Zoom Player. (2) Select whatever renderer you want to use in the media player settings. (3) Configure the media player and renderer to match your device setup and your personal likings. Done. Quote:

For upscaling I always found that Spline in ffdshow (is it spline36?) looks very close to Lanczos3. And because it s not parametric for tweaking ringing/alising I always used Lanczos. @tetsuo55 Quote:
But there is already a thread from madshi with this topic. |

so what settings do you recommend exactly? what do u mean by "tweaking ringing/aliasing"...the number of taps? Last edited by leeperry; 14th April 2009 at 19:29. |

@madshi:
feature request: - support for the built-in subtitle engine (like Haali's Renderer) (important !!!) - if possible:built-in shader support - if not possible: sharpener scripts (eg. complex sharpen2) after the resizer (or customizable shader support ???) question: isn't dxva support available at all by design ? (I tried CoreAVC CUDA, and it works, so it's not a big deal for nvidia users) Thanks

Seems though when enabling fullscreen it first shows it as entire screen, and only then applies aspect ratio correction. |
