Thanks for all the feedback on this. We had a meeting which went well but, guess what, they'll go for a 1080/50i online before standards converting to 720/59.94p. Their archive is almost completely PAL and it will save quite a lot of money by going this route.
Shame though. But it's good to be aware of the other workflows.

I completely agree with Jef.
If you can shoot 720p/59.94, do that - then master to it as well. Both the Ukon and Teranex can go from 720p/59.94 to either 525 or 625 very easily for your SD deliverables.

I have been through this calculus before. Tough.
I generally push towards Mastering in the Format of Delivery. Now on a
show that is sold in both PAL and NTSC, if it is SD I would choose PAL
-better standards convert. UNLESS the majority of archive is NTSC.
Then, by the end of the process, you would have double converted a lot
of the show. Hi expense, bad quality.
One trick you can use is NOT use a high end conversion during offline.
Use one of those cheap multi standard VHS machines. Make window dubs of
source (say it is NTSC) onto a PAL vhs (or beta, depending on deck
availability). Load this crappy window burn into the offline system.
When picture lock is reached, use the window burn info to have high
quality conversions done of only the footage actually needed. This can
save TONs of money for a production like this.
Same with up converts. Only up convert during the online.
Bottom line, I try figure out which production path/post path will have
the least amount of "conversions" during online. This will be the
most cost effective AND best looking show.
My opinion.

That would cost quute a bit, and then there's the cost of the S&W or terranex box as well. The final quality would probably be better that way though, rather than standards converting it at the time.

They are also planning to shoot interviews and reconstructions at HD. They haven't yet decided whether to shoot at an NTSC rate or a PAL one. If PAL they will have to do a standards conversion later on.

It also appears to be impossible to conform any 1080i material into a 720p sequence. Our HDCam deck will only give out a 1080 signal when upconverting the Beta SP material.
