My word... It's on my PC at work. How bizare...

[Well, I guess this is what happens when you use an operating system 
made by a company that thinks that PCs are games machines.]

Worship me for I can see the future :-P

Except WMM insists on outputting everything as wmv (or wma) at 25fps  
regardless of input; oh and last time I tried doesn't rotate video  
properly either.

Look up AVIsynth, the POV of video editing :-)

Looks like it might be useful for, say, applying temporal and spatial 
antialiasing. Probably not much use for actual editing though...

Just like POV isn't much use for actually modelling anything in 3D ;-)

Well, depends.

It's quite good for modelling algorithmic things, or things having a 
specific geometry. (E.g., it's much easier to put an engine block 
together with POV-Ray than trying to exactly align stuff with a mouse.)

But yeah, sure, there are plenty of things that POV-Ray won't easily do...

Haha.  Nobody aligns anything with a mouse alone the way you think, there 
are things called "constraints" in modelling packages.  Just select two 
"things" and click constrain, the software will give you the valid options 
for the things you selected (eg mate, align, coincident axis, constrain to 
surface etc).  I hate to think of the math involved in aligning conrods, 
pistons and a crankshaft in POV.  In a modeller it's very easy, the software 
does the math for to rotate/translate once you tell it what you actually 
want.

AVIsynth is like POV.  If you want to type in the exact start and end 
frames, exactly how long to fade, which files to load, exactly how to scale 
and move the picture at each frame, overlays etc then fine, it's possible, 
just like how modelling a room in POV is possible.  It's not a fast process, 
and usually involves trial and error, but certainly possible...

Well, I know this is supposedly how CAD works, but I have yet to see any 
readily available software that offers such power. (I did have a go at 
writing such a thing myself once though...)

I was thinking more that once you write a script to take a sequence at 
250 frames per second, add motion blur, and convert down to 25 frames 
per second, you can then process lots of videos quickly. With 
VirtualDub, I keep having to re-enter those settings. (And not miss any 
out...)
