True but I'm a bit weary oof using it for overcrank because the bit rate tops out at 24 and not 36Mbit as it does in normal 60fps overcrank.

Ahhh, I see. Just for your info, this may be true on the AF100 (I don't own one so I don't know for sure) but on the FS100
the bit rate is 28 instead of 24 when you shoot 1080 60p, it's a 'new' format that was added to AVCHD 2.0 I think. So not 36, but
a fair bit better than 24. The rational I heard behind it was that since there are more frames, there is less motion between
frames, thus the 'motion prediction' in a Long GOP format isn't working as hard, so even though it is only 28, it is 'roughly'
equivalent to the 1080 24p at 24Mbit. Of course that could all just be marketing speak for all I know. The 1080 60P at
28Mbit on the FS100 looks pretty good though. I use it all the time for speed ramping exactly like what you were talking about
doing.
