This video (or film) has 2:3 pulldown (it's 29.97) as shown by stepping thru it with separatefields. However, the 23.976 result after using TFM/Tdecimate shows duplicate frames. It's not just at scene changes. I tried all the modes/pp settings for TFM, and the one that worked for this clip (mode=7, pp=7) produced a frame drop later in the video (not in this clip) which was normally deinterlaced or field matched. I'm wondering if a threshold setting would work. I'm assuming that using another command in Tdecimate (I tried sundry) to remove extra dupes would also reduce the framerate, so that doesn't seem like the correct approach. Seems like it's TFM not outputting dupes in a correct order for Tdecimate.
