[John Heagy] "Which Canon records h.264 at 45Mbs? "
I believe that most (all?) Canon DSLR's shoot @ 45Mbps. Both of my 7D's shoot that when recording video. The 5DMarkIII I just rented shot around there as well.
Stephen - I generally transcode to ProRes422 as it holds up well through multiple recompressions - vfx, color grading, final export, etc. LT is pretty good, but it can break down quicker if you end up going through multiple generations of a file. However, if you're just strictly cutting it and are done after that then LT might just be all you need to use.
