Video Quality Tests Page 3

Still images and MPEG-2/MPEG-1 Format

Still images are used to investigate the behavior of the converter with a wider range of colors. Clarity, distortion and brightness is also investigated. Still images are compared against the images provided on the Pioneer disc, without any kind of conversion. We tried to use dark images as well as light images.

On this page, MPEG-2 and MPEG-1 media files were used (DVD and VCD). The same frame was extracted for every occasion, and the image was zoomed by 400%. Clicking on the images will reveal full sized high resolution images for better comparison.

This is a normal bright image. Although not all colors. were maintained exactly as in the original image, such behavior is rather common in DVD converters. Video quality was excellent, and even at 4Mbps DVD files we could watch good quality images. Of course, VCD video quality was reduced, and best results were observed, as expected, with 15mbps DVD media files. However, it should be noted that at such high bitrates, some video files might produce compatibility problems with some old DVD Players, but this should not worry most users, since most Hollywood movies commonly use 8Mbps or 9Mbps variable encoding.

This is a much brighter image and as you can easily see, brightness is maintained through the produced, converted files. We were surprised to see such good performance with such bright images.
