HQV Benchmark 2.0 Analysis – ATi, nVidia and Intel

Overview:
The first section is based around Video Conversion tests, followed up by a long series of Cadence related tests and lastly we get to examine colour upscaling errors.

Notes:
These tests stress the video processors ability to process data accurately, and is based around both stationary and moving elements within specific scenes. If the processing is successful and high quality the images will be rendered crisply and in a very clear manner. On the other hand, if the processing is poor then jaggies and artifacting will appear on the edges of moving objects.

Scoring:
The third test uses four sets of rotating bars, which range from bright white to dark gray. To score well in this test it is imperative to clearly see all four sets of bars to make a good final call. The monitor must be correctly calibrated to give a good judgement in this specific test.

Gray Bars (Score either 5, 3, 2, 1 or 0)
No artifacts on all gradients and all bars. – Scores 5
Artifacts only on darkest bars. – Scores 3
Artifacts on second darkest bars. – Scores 2
Artifacts on third gradient level bars. – Scores 1
Artifacts on brightness gradient levels. – Scores 0

This test exposes weaknesses with some deinterlacers in that they will not perform consistently at all brightness levels. It shows issues between foreground and background seperation brightness variables. This means the end result can show weaving artifacts, jaggies sometimes appear on darker bars, as they did with many of the lower end solutions on test today.
