If exporting QuickTime movies gets improved along with the QT rewrite, then encoding to any format will be generally faster. The 64-bitness of the G5 won't improve encoding small movies. iMovie and iDVD are not "Pro Apps" and most likely aren't 64-bit-aware.
Also, iMovie and iDVD, and specifically the encoding routines, are AltiVec accelerated, and AltiVec doesn't do 64 bit arithmetic. So regardless of whether the apps do take advantage of a 64-bit address space, the speed of the encoding routines will only get faster to the extent that the AltiVec unit gets faster.
i'm not really sure what youre addressing, but i'll try...
the pro video apps are already 64 bit, so all the people that use them already greatly benefit from having a G5 since its 64 bit.
if youre talking about my reference to the number of people using the pro video apps, all i can say is that my local production house, which teaches classes and is extremely hardcore Avid & PC based, is now considering adding Final Cut Pro b/c it is gaining a decent marketshare.
edit: we do some pretty big things (not just local stuff)
how are they already 64 bit and how are they already greatly benefitting from the G5 since its 64 bit? By the looks of it, the only benefit they get from the G5 is from the increase in clockspeed, and huge bus bandwidths. Not the fact that it's 64 Bit.
I just don't see how the pro video apps have needs that would be addressed by 64 bit as of now.

I was under the impression that apple made FCP HD and DVDSP3 64-bit earlier this year at NAB. 64 bit would come in handy when dealing with multiple HD video streams in real-time.
That would be great. (If FCP HD and DVD Studio Pro are 64 bit). I don't know how much that is going to help me in particular though. I am going to do some basic stuff with FCP HD and DVDSP3.
It only makes sense they would convert everything to 64 it as soon as possible to me. Any performance gain should lead to an advantage and more customers. At least, that is how I percieve it.

Hm. I'll have to be careful on this one, since I don't pay much attention to the video stuff. I don't think they're 64-bit apps, they've just optimized it to take advantage of the G5 architecture (I assume bus/memory related). They were "G5-optimized" last year... press release:
In addition to the real-time performance, Final Cut Pro 4.1?s rendering is now almost twice as fast at 32-bit floating point render jobs on a Power Mac G5 when compared to a Power Mac G4.
Odds are I could be way off base on a lot of this, I assume someone who knows more could point it out.

(And no, 64-bit AltiVec is not at all likely.)
