[FFmpeg-user] the trim filter

[Mark Filipak]

Is there some secret to the trim filter?

--filter_complex "split=2[i5][i6],
  [i5]trim=start_frame=481:end_frame=134047[o5],
  [i6]trim=start_frame=138745:end_frame=246719[o6],
  [o5][o6]concat=n=2"

I get "dup=481", instead, and wind up with 20.061708[3..] seconds of black frames preceding the 
segment I want, and the frame rate is 19.181 FPS.

Thanks -- Mark.
