Tool to transcode Canon PF24 MTS files to native 24p?
The usual tool recommended for this is JES Deinterlacer, which apparently has an adaptive method of finding and removing the 'smear' frames. I haven't used it myself.

The reason this is an issue is that the field cadence used for PF24 is (stupidly, IMO) different from the typical telecine cadence, which is what most 'inverse telecine' algos detect and remove. So applying standard inverse telecine just adds another layer of mess-up to the video.
