I did tests with my footage (DVX100a, 60i) and compared all the different combinations of settings in twixtor with the ones in FCP. For MY footage, my FCP method was better than twixtor. Used a monitor and not just the screen. I think someone needs to test their methods with their own footage. My footage was wakeboarding. The rider is traveling at 25mph past water and trees and sky all while doing fast, twisting flipping motions. the twixtor footage either distorted the rider, or the trees or the water, or blurred areas that moved too far from frame to frame.
