Parts of some shots I need did turn up as 60i fullscreen in the making of the SE doc, and so I'm gonna try and figure out how to IVTC them. Never done so before and there isn't much info out there for Macs, but I hear Cinematools can handle it.
There is also a plugin by nattress (nattress.com) which can try to remove ugly DV color artifacts, which is pretty remarkable, I'd like to have a look that that, but it's for sale rather than freely downloadable, and I don't see it on Acquisition P2P. If not for the DV artifacts this would be a perfect edit. Ah well.
