HQV (Test 4)

Test 4: Waving Flag

From the HQV manual:

Moving bars are a good way to evaluate the quality of motion adaptive deinterlacing and directional filtering, but the ideal test is to use a real-world object with rapidly moving lines at multiple, continuously shifting angles. The flag of the United States of America, with its 13 red and white stripes, is perfectly suited to this test.

As the flag slowly furls and unfurls in the wind, the 13 bars create a natural jaggies test, much like our Jaggies #2 pattern. The cleaner the edges of the red and white bars appear, the higher the quality of motion adaptive deinterlacing in use. Some lower-cost processors intentionally blur the image to mask scan line artifacts they can’t clean up, so pay attention also to background sharpness in this test!

In the ATI screenshot, the jaggies are less noticeable, but the background below the flag is also slightly blurred.  Both ATI and NVIDIA are showing jagged edges where white is overlapping red or vise-versa where it shouldn’t so both cards scored a 5.
