[FFmpeg-user] Detelecine: I got the right result from the wrong command?

[Alex Xu]

I tried running your exact command and got the same result. Dropped frame
173 and a later duplicated frame.

I've attached 15 frames here of the results.

I've attached 5 frames each of the original input, using detelecine, and
using fieldmatch+decimate with your command.

The 2nd frame of the original input was skipped with fieldmatch+decimate.
The frames are similar looking, but the character is a lot more blurry and
the sword is at a different angle.

Specifically detelecine2.png was skipped in fieldmatch+decimate.
