Test 8 t/m 16: Cadences
The following tests in the HQV suite are meant for the American standard of NTSC, and are of less importance for the European market. The film detail test checks if the 3:2 pulldown is operating as it should. To convert a movie shot in 24 frames per second in to an NTSC format some fields are used twice to produce the 30 images per second, and 3:2 Pulldown is responsible for recognizing these fields and delete them so that the 30fps NTSC video is converted back to fluent 24 fps video. 3:2 pulldown is extreme important for viewing all kinds of movies on NTSC DVD's! Both ATI and nVidia are very good in producing the correct images in this test.
After this test more cadence tests are being run, that test several rare authoring methods for NTSC-DVD’s. We will not describe all the cadence tests, as the need for this technique will be very rare in real life situations. A description of all these tests can be viewed at the HQV website, www.hqv.com. It is worth noting that the ATI card does recognize all the different varieties of the cadences, and the nVidia card does not. According to the HQV scoring table we had to award 5 points for every test completed, which results in a total of 40 points for ATI in these tests, and only 10 points for nVidia.
Test 17/18: Scrolling text / credits
The final two tests show a combination of interlaced credits on a non-interlaced video. The decoder should recognize both parts and deinterlace the correct parts while leaving the other parts as they are. Again a lot of standalone DVD players are not able to perform this action properly, but both ATI and nVidia score a decent 5 on the first test and a perfect 10 on the second.
