Moving pictures and MPEG-4 Format

The Plextor ConvertX PX-M402U's performance is most interesting when moving pictures and live scenes are investigated. Afterall, most end users will use the device to capture moving pictures and not still images. Clarity, distortion and brightness are also investigated. Still images are compared against 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, the MPEG-4 based profiles were used (MPEG-4 and DivX). 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.

This dark moving scene is best comparable when the full sized image is viewed. Again, slight colour distortion was introduced.
