De-Interlacing Quality: Jaggies Pattern 2
"Motion adaptive de-interlacing is just one step in cleaning up scan line artifacts. The video signal processor should also employ directional filtering to catch rapidly moving shapes that may change direction, speed, and angle.

In the second jaggies test, you'll see a cluster of three equally spaced white bars of the same thickness, rapidly moving up and down between a 5-degree and 35-degree angle. If all three bars appear to have jagged edges at all times, the video processor does not use directional filtering to smooth the images. If all three bars are smooth throughout the test, the video processing earns a passing grade."
NVIDIA has the clear advantage in this test, as ATI's de-interlacing shows jaggies in all three bars, while NVIDIA's leaves only the bottom bar with jagged edges.

Scoring Description
5 ALL THREE BARS HAVE SMOOTH EDGES AT ALL TIMES
3 THE TOP TWO BARS HAVE SMOOTH EDGES, BUT THE BOTTOM BAR DOES NOT
1 ONLY THE TOP BAR HAS SMOOTH EDGES
0 NONE OF THE BARS HAVE SMOOTH EDGES

    One thing about the guitar strings... Are you sure that they are artifacts and not the texture of the guitar strings? I do agree with one thing, they kinda look extreme...

    It is an acoustic base guitar and those do tend to use some pretty massive copper wound strings, but yeah I don't see anything that looks like interlacing artifacts in those shots.

    Regardless, thanks for the update Anand and I'll check back to see how things turn out. The next card I buy will most likely be for my media center so de-interlacing quality is on my priority list.

    I don't follow, the text at the bottom which the test askes to be compared defiantly doesn't show any interlacing artifacts in the posted pics while compression artifacts are mostly in the top right of the image and on the hands. The text does look a bit sharper on Nvidia, but best I can tell that is just from appling a sharpening fliter as that seems to be pretty obviously the case in the last shot with the fingers on piano keys and the slight shifts in geometry than can be seen there.

    Also, since the compression artifacts only appear in the first ATI shot, I can't help but wonder if that came about from downsampling as the jpg to under 40mb which nearly a quarter of what a full quality jpg of that resolution would be. Regardless, I am curious to see any further explnation of de-interlacing issues with the new r5xx chips as I would hate to try and upgrade my media center card only to wind up with worse de-interlacing than on my current r420 based card.

    The text itself is fine, it is the background image where the interlacing artifacts are seen. I'll see if I can get a better screen grab tonight.

    Take care,

    Apparently ATI isn't seeing what I'm seeing, so the issues may have been a driver problem, I will update you guys as soon as I have a driver/fix for the situation.

    Take care,

    I would if I could. Quit teasing us and give as the real deal, lol.

    INQ has benchies already. Not a surprise. Cards are matched.

    GRAKK!

    Interesting. Here's hoping that ATI improves on what they've started. Looking forward to the comoing months and what they bring.
