Hi Jason,
The “Show Duplicated Frames” indicator only seems to work with FCP digitized video that has a true timecode track. After Effects renders are ignored by the indicator. After Effects renders don’t have a true timecode track. If you go to the FCP pulldown Modify>Timecode and add a source timecode track to your file then the duplicate frames indicator should work.

Jason,
Did you email me with a FCP question? I saw an email from “Jason Spencer” in my bulk email but only after I had hit delete all. If it was you, could you email me again.
Thanks
