Moving pictures and MPEG-2/MPEG-1 Format

The Plextor ConvertX PX-M402U's performance is most interesting when moving picture and live scenes are investigated. Afterall, most end users will use the device to capture moving picture 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 profiles 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.

We recommend you see the full-sized pictures to investigate video quality. Above we present only the zoomed images, but by clicking on the images, you will see the full sized picture. VCD conversion was the worst of all, but this was to be expected since it uses MPEG-1 coding methods. The colour distortion factor was not as high as before.

Light effect and colour reproduction seems to be as vivid as the original file. Excellent performance. With these moving scenes, the M402U performed better than any other converter we used before. We were amazed to see that this picture that consist of dark and light areas is almost perfect.
