choppy motion
I just got a new 7d. Unfortunately I’m editing on Final Cut Express 4.0. I’m shooting 1080/24p. The footage looks great when I dump it onto my hard drive. I’m using MPEG Streamclip to convert it to AIC. I can’t use ProRes because I have FCE. So, it still looks great even as an AIC codec when I play the clip in quicktime. Here’s the problem: I import the clips into FCE, and fast motion (i.e. a car driving by) becomes slightly choppy. My hypothesis is it is due to the fact that I am editing in a 30p timeline. Is this accurate? I plan to get Final Cut Pro to resolve me editing issues, but I just wanted to make sure this is what was happening before I did so. Or if there is anything else I should be aware of. Perhaps it has something to do with the fact that FCE only supports 1080i footage in either 60 or 50p? Or a combination of all of the above? Any help is appreciated. Thanks!!

I don’t know FCE, but if you drop a 24p clip into a 30p sequence in FCP, it won’t play properly. Canon is about to release an EOS plugin for FCP that will allow easy transfer of DSLR files into FCP.
You didn’t mention if the camera was panning to follow the car, but if it was, there are definite speed limits for panning in 24p beyond which the image will stutter. If you look in a copy of the American Cinematographer Manual, there are charts/graphs that show you the proper pan speed for a given frame rate. If you exceed it the image will stutter.

Hello Jon,
You got it figured out. FCE will not work well with 24p. It will try but it will drop frames or become choppy. That is why I had to go to Pro. I was handed 24p material, and FCE would not cut it.
