Unlike VirtualDub, in Video Enhancer all filters, coders and decoders
work simultaneously in separate threads. For example, if you process your
video with two filters, then at the time coder compresses the first frame
second filter is already processing second frame, first filter is processing
third frame and decoder decompresses fourth frame.
A simple test was made on a Dual Core AMD Opteron 2.2GHz. A DV (dvsd) file
containing 1505 frames 720x576 was processed with a chain of 3 filters
(Asvzzz deinterlace, 2D Cleaner and MSU Smart Sharpen) and compressed with
XviD codec. In VirtualDub it took 184 seconds and only one logical CPU was
really active. In Video Enhancer absolutely the same process took 97 seconds
and all logical CPUs were working. This is 1.9 times faster!

Another test was performed on a Hyper-Threading Pentium 4 3.0 GHz with a
different DV file and same set of filters. VirtualDub completed the work
in 53 seconds while Video Enhancer did it in 46 seconds. That's
15% faster.
