12. Conclusion: Fast Motion Is Very Efficient, But Not A Universal Solution, Continued

In summary, it can be said that MPEG-4 is currently one of the most efficient compression procedures, as illustrated in the table below.

Compression Resolution Average Data Rate Quality
MPEG-1 352 x 288 Pixels 172 kB/s satisfactory
MPEG-2 352 x 288 Pixels 250 kB/s very good
MPEG-4 352 x 288 Pixels 80 kB/s very 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.
