Jaggies 1 test: out of 5 points

This test simply shows a rotating line in a circle. As the angle changes, interlacing makes the line appear to become stepped. Successful de-interlacing will remove this stepping.

The Jaggies 1 test

Software: 0 points
Most DVD playback software we know of can't cope with jaggies. Cyberlink's PowerDVD scored a zero on this test.

ATI Avivo: 5 points
With hardware acceleration enabled, the ATI cards did a great job of getting rid of them over 10 degrees. According to HQV's criteria, that gives them a full five points.

Geforce Purevideo: 5 points
With hardware acceleration, the Nvidia cards did a slightly better job than the ATI's Avivo, but they all qualified for the perfect five-point score

Jaggies 2 test: out of 5 points

Similar to the Jaggies 1 test, this test shows three small lines moving slightly within an arc. Once again, interlacing makes the line appear to become stepped, and de-interlacing will remove this stepping.

The Jaggies 2 test

Software: 0 points
Similar to the Jaggies 1 test, PowerDVD software without hardware acceleration has no method of eliminating the jaggies.

ATI Avivo: 5 points
Also the same as Jaggies 1, ATI smoothed out the lines well enough to garner a full five points.

Geforce Purevideo: 5 points
Nvidia once again did a little better than ATI, but all results were enough to get a full five points.

Flag test: out of 10 points

This test shows actual video of a flag blowing in the wind. Interlacing makes the stripes and edges appear stepped, while de-interlacing will remove this stepping.

The Flag test

Software: 0 points
PowerDVD can not fix this visual problem without hardware acceleration.

ATI Avivo: 10 points
Avivo did an excellent job of fixing the jaggies on the flag, which made a huge difference.

Geforce Purevideo: 10 points
Purevideo did a good job; I think ATI's looks slightly smoother but it qualifies for 10 points out of 10.
