I'm working with some 24pa footage in After Effects and although I've never had this issue before I'm now getting a really odd set of ghosted frames. I only recently noticed the issue after re-installing After Effects but I still have all the proper settings.

23.976 interpreted footage/comp frame rate.
no field dominance
etc.

Has anybody else had this issue with footage in After Effects before?

I've run through every available menu and to no avail I still have this issue, I really need to sort this out and any responses would be greatly appreciated!

I attached a link below of a quick sample of the problem, it's not that visible in this shot just because there's limited motion but it always lasts for about 2 or 3 frames and in the original footage from FCP there is no sign of any issue with the footage, only when imported into After Effects.

24pN creates footage usable at 23.976
24pa creates 24p footage with pulldown frames and should be used in a 29.97 comp

Change your comp to 29.97 or if you need to work in 23.976 then right click the footage, turn off frame blending and then interpret the footage back down to 23.976 with the remove pulldown option checked to whatever cadence it put the pulldown frames.

The blurring you are seeing is the frame blending as it tries to remove frames on the fly.

try exporting your footage from final cut and just watching it, its probably more to do with your capturing then your after effects
i would make sure you captured using advance pull down removal in final cut
if that doesnt work make sure you actually used 24pA instead of 24p, im sure capturing 24p (not Advanced) and removing an advanced pull down would create the ghosting effect by flagging the wrong frames.

and its 24pA that is actually 23.97 fps when the advance pull down is removed during capture
and 24p (not advanced) can be edited as 29.97 fps straight from a normal ntsc dv capture
and can be turned into 23.97 fps by using reverse telecine in cinema tools
