Transcoding data rate

I bought the new Canon VIXIA HFS10 because it can records at 24 mbps in their MXP mode. When I import the footage into FCP, it transcodes the footage to Apple Pro Res but the data rate is only at 18 mbps. When I record at the lower FXP at 17 mbps, FCP transcodes at 17 mbps. How do I get FCP to transcode at the higher 24 mbps? I am running FCP 6.05, 10.5.6, on MacBookPro (unibody)

You're confusing 24 megabits per second with 18 megabytes per second. Final Cut is doing exactly what you want here.

You're right in that I failed to notice the big "B" vs the little "b". However, why is FCP transcoding the less compressed MXP files to virtually the same rate as the more compressed FXP files?

Because it's transcoding everything to ProRes 422, which has a data rate that averages around 145 Mbps for 1080i.
