Moving pictures and MPEG-2/MPEG-1 Format

A DVD converter's performance is most interesting when moving pictures and live scenes are investigated. After all, most end users will use the ADS DVD Xpress to capture moving pictures and not still images. Clarity, distortion and brightness are also investigated. Still images are compared with the images provided on the Pioneer disc without any kind of conversion. We tried to use dark 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 photos will reveal full sized high resolution images for better comparison.

The DVD Xpress has no problems with light enhanced images. There was no distortion and video quality was retained at a high level.

Light effect and color reproduction seems to be as vivid as the original file. However, there was slight distortion and, especially with the VCD format, video quality was greatly reduced.
