snipped from the changelog:

"Version 1.3.0 released on 01-06-05
Added support for multiple processors; this should result in a significant speed increase for those with such systems. Check the "Use Multithreading" box to enable.
Added an option to save a reduced resolution version of the video (and reduced colorspace - YV12); this is VERY lossy and intented for video editors that use 'bait-and-switch'."

Im gonna start testing on my dual opteron and smp and Hyperthreaded systems, keep ya all posted!

edit1:
P4 3,6GHZ HT mode : 1,7GB RGB avi -> non-multithread, 51sec (not io bound)
P4 3,6GHZ HT mode : 1,7GB RGB avi -> multithread, 53sec (not io bound)
2xOpteron 2ghz : 1,7GB RGB avi -> non-multithread, 53sec (could be io bound)
2xOpteron 2ghz : 1,7GB RGB avi -> multithreaded, 56sec (could be io bound)

2Go of yv12 720*576@25fps:
dual athlon 2000+:
no multithread = 1min07sec
multithread = 47sec

=> a big boost but it realy depend of the source file, dependig of the source file i got form 70 to 90 % gain.
