Test Screens and MPEG-4 Format

Test patterns are used to test the clarity and brightness of the created files. The test screens are compared with the images provided on the Pioneer disc, without any kind of conversion. A gradual range of Black to White bands are used, as well as dark and light areas on the screen.

On this page, MPEG-4 based profiles were used (MPEG-4 and DivX). Clicking on the images will reveal high resolution images for better comparison.

Excellent black and white reproduction. Converters are not used to produce images of this quality when MPEG-4 coding method is used. Black areas remained black, and white areas remained white.

Nothing more to say. Again, excellent performance, even at low bitrates.
