24p, with 'pitch correction' to compensate.
Thanks, I feared that
They didn't do a bad job of it all being told. I have seen worse. And the pitch correction does go a long way towards compensating, it's *almost* imperceptable. But there are definitely purists out there who'd prefer them to be in their native 50i at least. Alas and alack that isn't gonna happen.
The Blu Rays do benefit from the lack of compression and a lossless audio track, but they also lose out with the 4% slow-down instead of being the speed that they should be. In practice there are both pluses and minuses to upgrading, depending on how well one perceives these things.
