MPEG-2352 x 288 Pixels250 kB/svery good
MPEG-4352 x 288 Pixels80 kB/svery good

MPEG procedures in comparison: with reference to attainable quality with a low data rate, the MPEG-4 is the best compression procedure.

All the MPEG-4 videos incorporate these properties. The picture shows the features of a test sequence with a 500 kBit/s data rate.
