Dropframed video auto correction

Hi, my first topic

we have material from Blackmagic Pocket Cinema Camera fully covered by drop-frame problem. Looks like we had ignored warning message (!) during recording and few hours need to by manually corrected. Footage has regular frame rate, just often frames are doubled, tripled and so on. Does any plugin for FPCX has possibility to detect exact frame and next frame and cut doubles off? I do understand that result will be jumpy, but this solution is the best one which i got in mind for the moment.

thanks for reply
