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 second test is identical to the previous one however the addition of a circular white mesh appears just within the circle outline. By including this white mesh the local motion adapticity capability of the video processor is being stressed. In practice this means the video processor has to draw the rotating dial with smooth edges but also has to redraw the mesh without any flickering distortion, jaggies or missing lines and without any additional distortion of the rotating dial.

Dial with Static Pattern (Score either 5, 2 or 0)
Mesh is stable and dial quality is as before. There may be a small halo around dial on the mesh. – Scores 5
Mesh is stable but some degradation of the dial or noticeable artifacts around the dial on the mesh. –  Scores 2
Mesh is flickering or dial quality has degraded. – Scores 0

We noticed that the NVG210 and Intel GMA X4500 suffered from a slight ‘halo' effect preceding the dial as it rotated through the white mesh. This halo while distracting is not classed as a failure in this test. As long as no lines are broken or missing, this counts as a ‘halo' and not an ‘artifact'.

A strong motion detection algorithm will use more fields to minimize the number of weaving artifacts on moving content. Various de-interlacers have different kinds of wake variances behind the objects and some even in front or in both positions. The size of his Halo effect (or motion trail) might be considered better as it often is connected with the number of fields that are used by the motion detection algorithm.

For a perfect score of 5 out of 5 the Mesh must be stable with the dial quality as before.
