Moving pictures and MPEG-2/MPEG-1 Format

A DVD converter's performance is most interesting when moving pictures and live scenes are investigated. Afterall, 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 form 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.

Again, when the VCD format was investigated, image shapes looks different from the original source, but light effects and brightness were retained. This is the more demanding scene investigated, and DVD Xpress performed very good, comparing with other converters on the market.

The ADS DVD Xpress showed its teeth with this moving scene test. We observed high quality images even at low bitrates, but again, the VCD format loses greatly in quality. In general, when using moving scenes, we observed very good reproduction of the original movie source. Excellent performance again.
