Intelligent Rendering in VideoFactory

Question: Does VideoFactory 2.0b have "Intelligent Rendering?" If so, how do I access it?

I thought that I saw that it did in the SF marketing literature last August when I upgraded, but I've not been able to find it. Vegas 3.0 apparently has this feature, but it doesn't show up in the VideoFactory/Vegas comparison chart:

Just to be clear, Intelligent Rendering is the ability to render only those portions of video that actually contain new pixels or audio from the original. Then, during a print back to DV tape, the portions of the original file that haven't changed are played at the appropriate moments in time. This saves a huge amount of rendering time in a cuts-only production, and also saves disk space, allowing much larger projects for a given disk size.

It appears that Vegas knows enough to render only the parts of events
that need to be rendered, but Video Factory renders an entire event if
any part of it needs to be rendered. A very simple workaround is to split
the events just outside of the area that needs to be rendered, thereby
creating short events that need rerendering and leaving the rest as a
separate event.

A little clunky, but it works. I've tried it and on some projects it's speeded
up the rendering time enormously! One project went from an 11 hour
render down to about 25 minutes.

Of course, this only applies when both the input and output files are the
same type of .avi format.
