what's the difference between low & high motion?

[Archer]

Hi all! I'm new here

What does low & high motion mean?
I think that it is old divx (divx 3.11) and if it so than can divx 5 play fully old divxed movies?

Hi and welcome.
High motion DivX was optimised for, well High motion.
Low motion for optimised for low motion.

In low bitrates the high motion codec will look a bit better in action scenes but in low action scenes it will look terribly. If you look closely at it you'll see a lot of compression errors even in high motion scenes. Since NanDub SBC, high motion has been made redundant.

..if it so than can divx 5 play fully old divxed movies?

Yes. The DivX 5 decoder can.
