This really is a matter of preference. I’m assuming HDCAM is not actually 24p, correct? And you won’t be doing a film out?
The extra frames are your pulldown cadence, so when you capture 24p,you are stripping out the pulldown and left with just the whole frames (resulting in smaller file sizes). But, if you have to go back to 59.94 or 29.97 for final delivery, you are going to have to add back in that pulldown though at some point (through a Kona card for example).
Personally, since I have the storage space and can handle the bandwidth of 59.94 that’s what I edit at. For a more “passionate” discussion, read Bob Zelin’s posts in the AJA Kona forum on the subjet.
