 If i want to transcode a file from progressiv to interlaced,
 the timecode will not be be the same.
 It doubles the last frame.

 Example:
 Original File 10:20:15:7
 After transcode 10:20:15:14




 {{{
 ffmpeg -i "%%i" -vcodec dnxhd -b:v 120M -q 1 -flags +ildct -vf
 "fps=50,format=yuv422p,scale=1920:1080,interlace,fieldorder=tff"
 -map_metadata 0:s:2 "coded\%%~ni_1080i50.mov"
 }}}


 many thanks
 Tim
